Does your organization have data integration requirements, like migrating data from Amazon S3 to Snowflake? You might have found your way to the right place. This article talks about a specific Data Engineering scenario where data gets moved from the popular Amazon S3 to Snowflake, a well-known cloud Data Warehousing Software. However, before we dive deeper into understanding the steps, let us first understand these individual systems for more depth and clarity.Prerequisites You will have a much easier time understanding the ways for setting up the Amazon S3 to Snowflake Integration if you have gone through the following aspects: An active account on Amazon Web Services.An active account on Snowflake.Working knowledge of Databases and Data Warehouses.Clear idea regarding the type of data to be transferred. How to Set Up Amazon S3 to Snowflake Integration This article delves into both the manual and using LIKE.TG methods in depth. You will also see some of the pros and cons of these approaches and would be able to pick the best method based on your use case. Let us now go through the two methods: Method 1: Manual ETL Process to Set up Amazon S3 to Snowflake Integration You can follow the below-mentioned steps to manually set up Amazon S3 to Snowflake Integration: Step 1: Configuring an S3 Bucket for AccessStep 2: Data PreparationStep 3: Copying Data from S3 Buckets to the Appropriate Snowflake TablesStep 4: Set up automatic data loading using SnowpipeStep 5: Manage data transformations during the data load from S3 to Snowflake Step 1: Configuring an S3 Bucket for Access To authenticate access control to an S3 bucket during a data load/unload operation, Amazon Web Services provides an option to create Identity Access Management (IAM) users with the necessary permissions. An IAM user creation is a one-time process that creates a set of credentials enabling a user to access the S3 bucket(s). In case there are a larger number of users, another option is to create an IAM role and assign this role to a set of users. The IAM role will be created with the necessary access permissions to an S3 bucket, and any user having this role can run data load/unload operations without providing any set of credentials. Step 2: Data Preparation There are a couple of things to be kept in mind in terms of preparing the data. They are: Compression: Compression of files stored in the S3 bucket is highly recommended, especially for bigger data sets, to help with the smooth and faster transfer of data. Any of the following compression methods can be used:gzipbzip2brotlizstandarddeflateraw deflateFile Format: Ensure the file format of the data files to be loaded matches with the file format from the table below – Step 3: Copying Data from S3 Buckets to the Appropriate Snowflake Tables Data copy from S3 is done using a ‘COPY INTO’ command that looks similar to a copy command used in a command prompt or any scripting language. It has a ‘source’, a ‘destination’, and a set of parameters to further define the specific copy operation. The two common ways to copy data from S3 to Snowflake are using the file format option and the pattern matching option: File format -Here’s an example : copy into abc_table from s3://snowflakebucket/data/abc_files credentials=(aws_key_id='$KEY_ID' aws_secret_key='$SECRET_KEY') file_format = (type = csv field_delimiter = ','); Pattern Matching – copy into abc_table from s3://snowflakebucket/data/abc_files credentials=(aws_key_id='$KEY_ID' aws_secret_key='$SECRET_KEY') pattern='*test*.csv'; Step 4: Set up Automatic Data Loadingusing Snowpipe As running COPY commands every time a data set needs to be loaded into a table is infeasible, Snowflake provides an option to automatically detect and ingest staged files when they become available in the S3 buckets. This feature is called automatic data loading using Snowpipe. Here are the main features of a Snowpipe – Snowpipe can be set up in a few different ways to look for newly staged files and load them based on a pre-defined COPY command. An example here is to create a Simple-Queue-Service notification that can trigger the Snowpipe data load.In the case of multiple files, Snowpipe appends these files into a loading queue. Generally, the older files are loaded first, however, this is not guaranteed to happen.Snowpipe keeps a log of all the S3 files that have already been loaded – this helps it identify a duplicate data load and ignore such a load when it is attempted. Step 5: Managing Data Transformations During the Data Load from S3 to Snowflake One of the cool features available on Snowflake is its ability to transform the data during the data load. In traditional ETL, data is extracted from one source and loaded into a stage table in a one-to-one fashion. Later on, transformations are done during the data load process between the stage and the destination table. However, with Snowflake, the intermediate stage table can be ignored, and the following data transformations can be performed during the data load – Reordering of columns: The order of columns in the data file doesn’t need to match the order of the columns in the destination table.Column omissions: The data file can have fewer columns than the destination table, and the data load will still go through successfully.Circumvent column length discrepancy: Snowflake provides for options to truncate the string length of data sets in the data file to align with the field lengths in the destination table. The above transformations are done through the use of select statements while performing the COPY command. These select statements are similar to how select SQL queries are written to query database tables, the only difference here is, the select statements pull certain data from a staged data file (instead of a database table) in an S3 bucket. Here is an example of a COPY command using a select statement to reorder the columns of a data file before going ahead with the actual data load – copy into abc_table(ID, name, category, price) from (select x.$1, x.$3, x.$4, x.$2 from @s3snowflakestage x) file_format = (format_name = csvtest); In the above example, the order of columns in the data file is different from that of the abc_table, hence, the select statement calls out specific columns using the $*number* syntax to match with the order of the abc_table. Limitations of Manual ETL Process to Set up Amazon S3 to Snowflake Integration After reading this blog, it may appear as if writing custom ETL scripts to achieve the above steps to move data from S3 to Snowflake is not that complicated. However, in reality, there is a lot that goes into building these tiny things in a coherent, robust way to ensure that your data pipelines are going to function reliably and efficiently. Some specific challenges to that end are – Other than one-of-use of the COPY command for specific, ad-hoc tasks, as far as data engineering and ETL goes, this whole chain of events will have to be automated so that real-time data is available as soon as possible for analysis. Setting up Snowpipe or any similar solution to achieve that reliably is no trivial task.On top of setting up and automating these tasks, the next thing a growing data infrastructure is going to face is scaling. Depending on the growth, things can scale up really quickly and if you don’t have a dependable, data engineering backbone that can handle this scale, it can become a problem.With functionalities to perform data transformations, a lot can be done in the data load phase, however, again with scale, there are going to be so many data files and so many database tables, at which point, you’ll need to have a solution already deployed that can keep track of these updates and stay on top of it.

Amazon Redshift is a fully managed, distributed Relational Data Warehouse system. It is capable of performing queries efficiently over petabytes of data. Nowadays, Redshift has become a natural choice for many for their Data Warehousing needs. This makes it important to understand the concept of Redshift Sortkeys to derive optimum performance from it. This article will introduce Amazon Redshift Data Warehouse and the Redshift Sortkeys. It will also shed light on the types of Sort Keys available and their implementation in Data Warehousing. If leveraged rightly, Sort Keys can help optimize the query performance on an Amazon Redshift Cluster to a greater extent. Read along to understand the importance of Sort Keys and the points that you must keep in mind while selecting a type of Sort Key for your Data Warehouse! What is Redshift Sortkey? Amazon Redshift is a well-known Cloud-based Data Warehouse. Developed by Amazon, Redshift has the ability to quickly scale and deliver services to users, reducing costs and simplifying operations. Moreover, it links well with other AWS services, for example, AWS Redshift analyzes all data present in data warehouses and data lakes efficiently. With machine learning, massively parallel query execution, and high-performance disk columnar storage, Redshift delivers much better speed and performance than its peers. ​AWS Redshift is easy to operate and scale, so users don’t need to learn any new languages. By simply loading the cluster and using your favorite tools, you can start working on Redshift. The following video tutorial will help you in starting your journey with AWS Redshift. To learn more about Amazon Redshift, visit here. Introduction to Redshift Sortkeys Redshift Sortkeys determines the order in which rows in a table are stored. Query performance is improved when Redshift Sortkeys are properly used as it enables the query optimizer to read fewer chunks of data filtering out the majority of it. During the process of storing your data, some metadata is also generated, for example, the minimum and maximum values ​​of each block are saved and can be accessed directly without repeating the data. Every time a query is executed. This metadata is passed to the query planner, which extracts this information to create more efficient execution plans. This metadata is used by the Sort Keys to optimizing the query processing. Redshift Sortkeys allow skipping large chunks of data during query processing. Fewer data to scan means a shorter processing time, thereby improving the query’s performance. To learn more about Redshift Sortkeys, visit here.

Types of Redshift Sortkeys There can be multiple columns defined as Sort Keys. Data stored in the table can be sorted using these columns. The query optimizer uses this sort of ordered table while determining optimal query plans. There are 2 types of Amazon Redshift Sortkey available: Compound Redshift Sortkeys Interleaved Redshift Sortkeys 1) Compound Redshift Sortkeys These are made up of all the columns that are listed in the Redshift Sortkeys definition during the creation of the table, in the order that they are listed. Therefore, it is advisable to put the most frequently used column at the first in the list. COMPOUND is the default Sort type. The Compound Redshift Sortkeys might speed up joins, GROUP BY and ORDER BY operations, and window functions that use PARTITION BY. Download the Cheatsheet on How to Set Up High-performance ETL to Redshift Learn the best practices and considerations for setting up high-performance ETL to Redshift For example, let’s create a table with 2 Compound Redshift sortkeys. CREATE TABLE customer ( c_customer_id INTEGER NOT NULL, c_country_id INTEGER NOT NULL, c_name VARCHAR(100) NOT NULL) COMPOUND SORTKEY(c_customer_id, c_country_id); You can see how data is stored in the table, it is sorted by the columns c_customer_id and c_country_id. Since the column c_customer_id is first in the list, the table is first sorted by c_customer_id and then by c_country_id. As you can see in Figure.1, if you want to get all country IDs for a customer, you would require access to one block. If you need to get IDs for all customers with a specific country, you need to access all four blocks. This shows that we are unable to optimize two kinds of queries at the same time using Compound Sorting. 2) Interleaved Redshift Sortkeys Interleaved Sort gives equal weight to each column in the Redshift Sortkeys. As a result, it can significantly improve query performance where the query uses restrictive predicates (equality operator in WHERE clause) on secondary sort columns. Adding rows to a Sorted Table already containing data affects the performance significantly. VACUUM and ANALYZE operations should be used regularly to re-sort and update the statistical metadata for the query planner. The effect is greater when the table uses interleaved sorting, especially when the sort columns include data that increases monotonically, such as date or timestamp columns. For example, let’s create a table with Interleaved Sort Keys. CREATE TABLE customer (c_customer_id INTEGER NOT NULL, c_country_id INTEGER NOT NULL) INTERLEAVED SORTKEY (c_customer_id, c_country_id); As you can see, the first block stores the first two customer IDs along with the first two country IDs. Therefore, you only scan 2 blocks to return data to a given customer or a given country. The query performance is much better for the large table using interleave sorting. If the table contains 1M blocks (1 TB per column) with an interleaved sort key of both customer ID and country ID, you scan 1K blocks when you filter on a specific customer or country, a speedup of 1000x compared to the unsorted case. Choosing the Ideal Redshift Sortkey Both Redshift Sorkeys have their own use and advantages. Keep the following points in mind for selecting the right Sort Key: Use Interleaved Sort Keyswhen you plan to use one column as Sort Key or when WHERE clauses in your query have highly selective restrictive predicates. Or if the tables are huge. You may want to check table statistics by querying the STV_BLOCKLIST system table. Look for the tables with a high number of 1MB blocks per slice and distributed over all slices. Use Compound Sort Keys when you have more than one column as Sort Key, when your query includes JOINS, GROUP BY, ORDER BY, and PARTITION BY when your table size is small. Don’t use an Interleaved Sort Key on columns with monotonically increasing attributes, like an identity column, dates, or timestamps. This is how you can choose the ideal Sort Key in Redshift for your unique data needs. Conclusion This article introduced Amazon Redshift Data Warehouse and the Redshift Sortkeys. Moreover, it provided a detailed explanation of the 2 types of Redshift Sortkeys namely, Compound Sort Keys and Interleaved Sort Keys. The article also listed down the points that you must remember while choosing Sort Keys for your Redshift Data warehouse.

Apache Kafka is a distributed message broker designed to handle large volumes of real-time data efficiently. Unlike traditional brokers like ActiveMQ and RabbitMQ, Kafka runs as a cluster of one or more servers. This makes it highly scalable, and due to this distributed nature, it has inbuilt fault tolerance while delivering higher throughput when compared to its counterparts.But, tackling the challenges while installing Kafka is not easy. This article will walk you through the steps to Install Kafka on Ubuntu 20.04 using simple 8 steps. It will also provide you with a brief introduction to Kafka install Ubuntu 20.04. Let’s get started. How to Install Kafka on Ubuntu 20.04 To begin Kafka installation on Ubuntu, ensure you have the necessary dependencies installed: A server running Ubuntu 20.04 with at least 4 GB of RAM and a non-root user with sudo access. If you do not already have a non-root user, follow our Initial Server Setup tutorial to set it up. Installations with fewer than 4GB of RAM may cause the Kafka service to fail. OpenJDK 11 is installed on your server. To install this version, refer to our post on How to Install Java using APT on Ubuntu 20.04. Kafka is written in Java and so requires a JVM. Let’s try to understand the procedure to install Kafka on Ubuntu. Below are the steps you can follow to install Kafka on Ubuntu: Step 1: Install Java and Zookeeper Step 2: Create a Service User for Kafka Step 3: Download Apache Kafka Step 4: Configuring Kafka Server Step 5: Setting Up Kafka Systemd Unit Files Step 6: Testing Installation Step 7: Hardening Kafka Server Step 8: Installing KafkaT (Optional) Simplify Integration Using LIKE.TG ’s No-code Data Pipeline What if there is already a platform that uses Kafka and makes the replication so easy for you? LIKE.TG Data helps you directly transfer data from Kafka and 150+ data sources (including 40+ free sources) to Business Intelligence tools, Data Warehouses, or a destination of your choice in a completely hassle-free automated manner. Its fault-tolerant architecture ensures that the data is replicated in real-time and securely with zero data loss. Sign up here for a 14-Day Free Trial! Step 1: Install Java and Bookeeper Kafka is written in Java and Scala and requires jre 1.7 and above to run it. In this step, you need to ensure Java is installed. sudo apt-get update sudo apt-get install default-jre ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. Kafka uses Zookeeper for maintaining the heartbeats of its nodes, maintaining configuration, and most importantly to elect leaders. sudo apt-get install zookeeperd You will now need to check if Zookeeper is alive and if it’s OK telnet localhost 2181 at Telnet prompt, You will have to enter ruok (are you okay) if it’s all okay it willend the telnet session andreply with imok Step 2: Create a Service User for Kafka As Kafka is a network application creating a non-root sudo user specifically for Kafka minimizes the risk if the machine is to be compromised. $ sudo adduser kafka Follow the Tabs and set the password to create Kafka User. Now, you have to add the User to the Sudo Group, using the following command: $ sudo adduser kafka sudo Now, your User is ready, you need to log in using, the following command: $ su -l kafka Step 3: Download Apache Kafka Now, you need to download and extract Kafka binaries in your Kafka user’s home directory. You can create your directory using the following command: $ mkdir ~/Downloads You need to download the Kafka binaries using Curl: $ curl "https://downloads.apache.org/kafka/2.6.2/kafka_2.13-2.6.2.tgz" -o ~/Downloads/kafka.tgz Create a new directory called Kafka and change your path to this directory to make it your base directory. $ mkdir ~/kafka cd ~/kafka Now simply extract the archive you have downloaded using the following command: $ tar -xvzf ~/Downloads/kafka.tgz --strip 1 –strip 1 is used to ensure that the archived data is extracted in ~/kafka/. Step 4: Configuring Kafka Server The default behavior of Kafka prevents you from deleting a topic. Messages can be published to a Kafka topic, which is a category, group, or feed name. You must edit the configuration file to change this. The server.properties file specifies Kafka’s configuration options. Use nano or your favorite editor to open this file: $ nano ~/kafka/config/server.properties Add a setting that allows us to delete Kafka topics first. Add the following to the file’s bottom: delete.topic.enable = true Now change the directory for storing logs: log.dirs=/home/kafka/logs Now you need to Save and Close the file. The next step is to set up Systemd Unit Files. Step 5: Setting Up Kafka Systemd Unit Files In this step, you need to create systemd unit files for the Kafka and Zookeeper service. This will help to manage Kafka services to start/stop using the systemctl command. Create systemd unit file for Zookeeper with below command: $ sudo nano /etc/systemd/system/zookeeper.service Next, you need to add the below content: [Unit] Requires=network.target remote-fs.target After=network.target remote-fs.target [Service] Type=simple User=kafka ExecStart=/home/kafka/kafka/bin/zookeeper-server-start.sh /home/kafka/kafka/config/zookeeper.properties ExecStop=/home/kafka/kafka/bin/zookeeper-server-stop.sh Restart=on-abnormal [Install] WantedBy=multi-user.target Save this file and then close it. Then you need to create a Kafka systemd unit file using the following command snippet: $ sudo nano /etc/systemd/system/kafka.service Now, you need to enter the following unit definition into the file: [Unit] Requires=zookeeper.service After=zookeeper.service [Service] Type=simple User=kafka ExecStart=/bin/sh -c '/home/kafka/kafka/bin/kafka-server-start.sh /home/kafka/kafka/config/server.properties > /home/kafka/kafka/kafka.log 2>1' ExecStop=/home/kafka/kafka/bin/kafka-server-stop.sh Restart=on-abnormal [Install] WantedBy=multi-user.target This unit file is dependent on zookeeper.service, as specified in the [Unit] section. This will ensure that zookeeper is started when the Kafka service is launched.The [Service] line specifies that systemd should start and stop the service using the kafka-server-start.sh and Kafka-server-stop.sh shell files. It also indicates that if Kafka exits abnormally, it should be restarted.After you’ve defined the units, use the following command to start Kafka: $ sudo systemctl start kafka Check the Kafka unit’s journal logs to see if the server has started successfully: $ sudo systemctl status kafka Output: kafka.service Loaded: loaded (/etc/systemd/system/kafka.service; disabled; vendor preset: enabled) Active: active (running) since Wed 2021-02-10 00:09:38 UTC; 1min 58s ago Main PID: 55828 (sh) Tasks: 67 (limit: 4683) Memory: 315.8M CGroup: /system.slice/kafka.service ├─55828 /bin/sh -c /home/kafka/kafka/bin/kafka-server-start.sh /home/kafka/kafka/config/server.properties > /home/kafka/kafka/kafka.log 2>1 └─55829 java -Xmx1G -Xms1G -server -XX:+UseG1GC -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35 -XX:+ExplicitGCInvokesConcurrent -XX:MaxInlineLevel=15 -Djava.awt.headless=true -Xlog:gc*:file=> Feb 10 00:09:38 cart-67461-1 systemd[1]: Started kafka.service. On port 9092, you now have a Kafka server listening. The Kafka service has been begun. But if you rebooted your server, Kafka would not restart automatically. To enable the Kafka service on server boot, run the following commands: $ sudo systemctl enable zookeeper $ sudo systemctl enable kafka You have successfully done the setup and installation of the Kafka server. Step 6: Testing installation In this stage, you’ll put your Kafka setup to the test. To ensure that the Kafka server is functioning properly, you will publish and consume a “Hello World” message. In order to publish messages in Kafka, you must first: A producer who allows records and data to be published to topics. A person who reads communications and data from different themes. To get started, make a new topic called TutorialTopic: $ ~/kafka/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic TutorialTopic The kafka-console-producer.sh script can be used to build a producer from the command line. As arguments, it expects the hostname, port, and topic of the Kafka server. The string “Hello, World” should now be published to the TutorialTopic topic: $ echo "Hello, World" | ~/kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic TutorialTopic > /dev/null Using the Kafka-console-consumer.sh script, establish a Kafka consumer. As parameters, it requests the ZooKeeper server’s hostname and port, as well as a topic name. Messages from TutorialTopic are consumed by the command below. Note the usage of the —from-beginning flag, which permits messages published before the consumer was launched to be consumed: $ ~/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic TutorialTopic --from-beginning Hello, World will appear in your terminal if there are no configuration issues: Hello, World The script will keep running while it waits for further messages to be published. Open a new terminal window and log into your server to try this.Start a producer in this new terminal to send out another message: $ echo "Hello World from Sammy at LIKE.TG Data!" | ~/kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic TutorialTopic > /dev/null This message will appear in the consumer’s output: Hello, World Hello World from Sammy at LIKE.TG Data! To stop the consumer script, press CTRL+C once you’ve finished testing.On Ubuntu 20.04, you’ve now installed and set up a Kafka server. You’ll do a few fast operations to tighten the security of your Kafka server in the next phase. Step 7: Hardening Kafka Server You can now delete the Kafka user’s admin credentials after your installation is complete. Log out and back in as any other non-root sudo user before proceeding. Type exit if you’re still in the same shell session as when you started this tutorial. Remove the Kafka user from the sudo group: $ sudo deluser kafka sudo Lock the Kafka user’s password with the passwd command to strengthen the security of your Kafka server even more. This ensures that no one may use this account to log into the server directly: $ sudo passwd kafka -l Only root or a sudo user can log in as Kafka at this time by entering the following command: $ sudo su - kafka If you want to unlock it in the future, use passwd with the -u option: $ sudo passwd kafka -u You’ve now successfully restricted the admin capabilities of the Kafka user. You can either go to the next optional step, which will add KafkaT to your system, to start using Kafka. Step 8: Installing KafkaT (Optional) Airbnb created a tool called KafkaT. It allows you to view information about your Kafka cluster and execute administrative activities directly from the command line. You will, however, need Ruby to use it because it is a Ruby gem. To build the other gems that KafkaT relies on, you’ll also need the build-essential package. Using apt, install them: $ sudo apt install ruby ruby-dev build-essential The gem command can now be used to install KafkaT: $ sudo CFLAGS=-Wno-error=format-overflow gem install kafkat To suppress Zookeeper’s warnings and problems during the kafkat installation process, the “Wno-error=format-overflow” compiler parameter is required. The configuration file used by KafkaT to determine the installation and log folders of your Kafka server is.kafkatcfg. It should also include a KafkaT entry that points to your ZooKeeper instance. Make a new file with the extension .kafkatcfg: $ nano ~/.kafkatcfg To specify the required information about your Kafka server and Zookeeper instance, add the following lines: { "kafka_path": "~/kafka", "log_path": "/home/kafka/logs", "zk_path": "localhost:2181" } You are now ready to use KafkaT. For a start, here’s how you would use it to view details about all Kafka partitions: $ kafkat partitions You will see the following output: [DEPRECATION] The trollop gem has been renamed to optimist and will no longer be supported. Please switch to optimist as soon as possible. /var/lib/gems/2.7.0/gems/json-1.8.6/lib/json/common.rb:155: warning: Using the last argument as keyword parameters is deprecated ... Topic Partition Leader Replicas ISRs TutorialTopic 0 0 [0] [0] __consumer_offsets 0 0 [0] [0] ... ... You will see TutorialTopic, as well as __consumer_offsets, an internal topic used by Kafka for storing client-related information. You can safely ignore lines starting with __consumer_offsets. To learn more about KafkaT, refer to its GitHub repository. Conclusion This article gave you a comprehensive guide to Apache Kafka and Ubuntu 20.04.

When it comes to migrating data from MongoDB to PostgreSQL, I’ve had my fair share of trying different methods and even making rookie mistakes, only to learn from them. The migration process can be relatively smooth if you have the right approach, and in this blog, I’m excited to share my tried-and-true methods with you to move your data from MongoDB to PostgreSQL.In this blog, I’ll walk you through three easy methods: two automated methods for a faster and simpler approach and one manual method for more granular control. Choose the one that works for you. Let’s begin! What is MongoDB? MongoDB is a modern, document-oriented NoSQL database designed to handle large amounts of rapidly changing, semi-structured data. Unlike traditional relational databases that store data in rigid tables, MongoDB uses flexible JSON-like documents with dynamic schemas, making it an ideal choice for agile development teams building highly scalable and available internet applications. At its core, MongoDB features a distributed, horizontally scalable architecture that allows it to scale out across multiple servers as data volumes grow easily. Data is stored in flexible, self-describing documents instead of rigid tables, enabling faster iteration of application code. What is PostgreSQL? PostgreSQL is a powerful, open-source object-relational database system that has been actively developed for over 35 years. It combines SQL capabilities with advanced features to store and scale complex data workloads safely. One of PostgreSQL’s core strengths is its proven architecture focused on reliability, data integrity, and robust functionality. It runs on all major operating systems, has been ACID-compliant since 2001, and offers powerful extensions like the popular PostGIS for geospatial data. Differences between MongoDB PostgreSQL Reasons to Sync I have found that MongoDB is a distributed database that excels in handling modern transactional and analytical applications, particularly for rapidly changing and multi-structured data. On the other hand, PostgreSQL is an SQL database that provides all the features I need from a relational database. Differences Data Model: MongoDB uses a document-oriented data model, but PostgreSQL uses a table-based relational model. Query Language: MongoDB uses query syntax, but PostgreSQL uses SQL. Scaling: MongoDB scales horizontally through sharding, but PostgreSQL scales vertically on powerful hardware. Community Support: PostgreSQL has a large, mature community support, but MongoDB’s is still growing. Reasons to migrate from MongoDB to PostgreSQL: Better for larger data volumes: While MongoDB works well for smaller data volumes, PostgreSQL can handle larger amounts of data more efficiently with its powerful SQL engine and indexing capabilities. SQL and strict schema: If you need to leverage SQL or require a stricter schema, PostgreSQL’s relational approach with defined schemas may be preferable to MongoDB’s schemaless flexibility. Transactions: PostgreSQL offers full ACID compliance for transactions, MongoDB has limited support for multi-document transactions. Established solution: PostgreSQL has been around longer and has an extensive community knowledge base, tried and tested enterprise use cases, and a richer history of handling business-critical workloads. Cost and performance: For large data volumes, PostgreSQL’s performance as an established RDBMS can outweigh the overhead of MongoDB’s flexible document model, especially when planning for future growth. Integration: If you need to integrate your database with other systems that primarily work with SQL-based databases, PostgreSQL’s SQL support makes integration simpler.

To manually transfer data from MongoDB to PostgreSQL, I’ll follow a straightforward ETL (Extract, Transform, Load) approach. Here’s how I do it: Prerequisites and Configurations MongoDB Version: For this demo, I am using MongoDB version 4.4. PostgreSQL Version: Ensure you have PostgreSQL version 12 or higher installed. MongoDB and PostgreSQL Installation: Both databases should be installed and running on your system. Command Line Access: Make sure you have access to the command line or terminal on your system. CSV File Path: Ensure the CSV file path specified in the COPY command is accurate and accessible from PostgreSQL. Step 1: Extract the Data from MongoDB First, I use the mongoexport utility to export data from MongoDB. I ensure that the exported data is in CSV file format. Here’s the command I run from a terminal: mongoexport --host localhost --db bookdb --collection books --type=csv --out books.csv --fields name,author,country,genre This command will generate a CSV file named books.csv. It assumes that I have a MongoDB database named bookdb with a book collection and the specified fields. Step 2: Create the PostgreSQL Table Next, I create a table in PostgreSQL that mirrors the structure of the data in the CSV file. Here’s the SQL statement I use to create a corresponding table: CREATE TABLE books ( id SERIAL PRIMARY KEY, name VARCHAR NOT NULL, position VARCHAR NOT NULL, country VARCHAR NOT NULL, specialization VARCHAR NOT NULL ); This table structure matches the fields exported from MongoDB. Step 3: Load the Data into PostgreSQL Finally, I use the PostgreSQL COPY command to import the data from the CSV file into the newly created table. Here’s the command I run: COPY books(name,author,country,genre) FROM 'C:/path/to/books.csv' DELIMITER ',' CSV HEADER; This command loads the data into the PostgreSQL books table, matching the CSV header fields to the table columns. Pros and Cons of the Manual Method Pros: It’s easy to perform migrations for small data sets. I can use the existing tools provided by both databases without relying on external software. Cons: The manual nature of the process can introduce errors. For large migrations with multiple collections, this process can become cumbersome quickly. It requires expertise to manage effectively, especially as the complexity of the requirements increases. Integrate MongoDB to PostgreSQL in minutes.Get your free trial right away!

SIGN UP HERE FOR A 14-DAY FREE TRIAL! Method 2: Manual ETL process to Set up Google Analytics to MySQL Integration Below is a method to manually set up Google Analytics to MySQL Integration: Step 1: Getting data from Google Analytics Google Analytics makes the click event data available through its Reporting API V4. Reporting API provides two sets of Rest API to address two specific use cases. Get aggregated analytics information on user behavior on your site on the basis of available dimensions – Google calls these metrics and dimensions. Metrics are aggregated information that you can capture and dimensions are the terms on which metrics are aggregated. For example, the number of users will be a metric and time will be a dimension. Get activities of a specific user – For this, you need to know the user id or client id. An obvious question then is how do you know the user id or client id. You will need to modify some bits in the client-side google analytics function that you are going to use and capture the client id. Google does not specifically tell you how to do this, but there is ample documentation on the internet about it. Please consult the laws and restrictions in your local country before attempting this, since the legality of this will depend on the privacy laws of the country. You will also need to go to the Google Analytics dashboard and register the client id as a new dimension. Google Analytics APIs use oAuth 2.0 as the authentication protocol. Before accessing the APIs, the user first needs to create a service account in the Google Analytics dashboard and generate authentication tokens. Let us review how this can be done. Go to google service accounts page and select a project. If you have not already created a project, create a project. Click on Create Service Account. You can ignore the permissions for now. On the ‘Grant users access to this service account’ section, click Create key Select JSON as the format for your key. Click Create a key and you will be prompted with a dialogue to save the key in your local computer. Save the key. We will be using the information from this step when we actually access the API. This API is now deprecated and all existing customers will lose access by July 1, 2024. Data API v1 is now being used instead of it. Limitations of using the manual method to load data from analytics to MySQL are: Requirement of Coding Expertise: The manual method requires organizations to have a team of experts who can write and debug codes manually in a timely manner. Security Risk: Sensitive API keys and access credentials of both Google Analytics and MySQL must be stored within the script code. This poses a significant security risk Use Cases for Google Analytics MySQL Connection There are several benefits of integrating data from Google Analytics 4 (GA4) to MySQL. Here are a few use cases: Advanced Analytics: You can perform complex queries and data analysis on your Google Analytics 4 (GA4) data because of MySQL’s powerful data processing capabilities, extracting insights that wouldn’t be possible within Google Analytics 4 (GA4) alone. Data Consolidation: Syncing to MySQL allows you to centralize your data for a holistic view of your operations if you’re using multiple other sources along with Google Analytics 4 (GA4). This helps to set up a changed data capture process so you never have any discrepancies in your data again. Historical Data Analysis: Google Analytics 4 (GA4) has limits on historical data. Long-term data retention and analysis of historical trends over time is possible because of syncing data to MySQL. Data Security and Compliance: MySQL provides robust data security features. When you load data from Analytics to MySQL, it ensures your data is secured and allows for advanced data governance and compliance management. Scalability: MySQL can handle large volumes of data without affecting performance. Hence, it provides an ideal solution for growing businesses with expanding Google Analytics 4 (GA4) data. Data Science and Machine Learning: When you connect Google Analytics to MySQL, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more. Reporting and Visualization: While Google Analytics 4 (GA4) provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to MySQL, providing more advanced business intelligence options. Download the Ultimate Guide on Database Replication Learn the 3 ways to replicate databases which one you should prefer. Step 2: Accessing Google Reporting API V4 Google provides easy-to-use libraries in Python, Java, and PHP to access its reporting APIs. It is best to use these APIs to download the data since it would be a tedious process to access these APIs using command-line tools like CURL. Here we will use the Python library to access the APIs. The following steps detail the procedure and code snippets to load data from Google Analytics to MySQL. Use the following command to install the Python GA library to your environment. sudo pip install --upgrade google-api-python-client This assumes the Python programming environment is already installed and works fine. We will now start writing the script for downloading the data as a CSV file. Import the required libraries. from apiclient.discovery import build from oauth2client.service_account import ServiceAccountCredentials Initialize the required variables. SCOPES = [‘https://www.googleapis.com/auth/analytics.readonly’] KEY_FILE_LOCATION = ‘<REPLACE_WITH_JSON_FILE>’ VIEW_ID = ‘<REPLACE_WITH_VIEW_ID>’ The above variables are required for OAuth authentication. Replace the key file location and view id with what we obtained in the first service creation step. View ids are the views from which you will be collecting the data. To get the view id of a particular view that you have already configured, go to the admin section, click on the view that you need, and go to view settings. Build the required objects. credentials = ServiceAccountCredentials.from_json_keyfile_name(KEY_FILE_LOCATION, SCOPES) #Build the service object. analytics = build(‘analyticsreporting’, ‘v4’, credentials=credentials) Execute the method to get the data. The below query is for getting the number of users aggregated by country from the last 7 days. response = analytics.reports().batchGet( body={ ‘reportRequests’: [ { ‘viewId’: VIEW_ID, ‘dateRanges’: [{‘startDate’: ‘7daysAgo’, ‘endDate’: ‘today’}], ‘metrics’: [{‘expression’: ‘ga:sessions’}], ‘dimensions’: [{‘name’: ‘ga:country’}] }] } ).execute() Parse the JSON and write the contents into a CSV file. import pandas as pd from pandas.io.json import json_normalize reports = response[‘reports’][0] columnHeader = reports[‘columnHeader’][‘dimensions’] metricHeader = reports[‘columnHeader’][‘metricHeader’][‘metricHeaderEntries’] columns = columnHeader for metric in metricHeader: columns.append(metric[‘name’]) data = json_normalize(reports[‘data’][‘rows’]) data_dimensions = pd.DataFrame(data[‘dimensions’].tolist()) data_metrics = pd.DataFrame(data[‘metrics’].tolist()) data_metrics = data_metrics.applymap(lambda x: x[‘values’]) data_metrics = pd.DataFrame(data_metrics[0].tolist()) result = pd.concat([data_dimensions, data_metrics], axis=1, ignore_index=True) result.to_csv(‘reports.csv’) Save the script and execute it. The result will be a CSV file with the following columns Id , ga:country, ga:sessions This file can be directly loaded to a MySQL table using the below command. Please ensure the table is already created. LOAD DATA INFILE’products.csv’ INTO TABLE customers FIELDS TERMINATED BY ‘,’ ENCLOSED BY ‘“’ LINES TERMINATED BY ‘rn’ ; That’s it! You now have your google analytics data in your MySQL. Now that we know how to get the Google Analytics data using custom code, let’s look into the limitations of using this method. Challenges of Building a Custom Setup The method even though elegant, requires you to write a lot of custom code. Google’s output JSON structure is a complex one and you may have to make changes to the above code according to the data you query from the API. This approach will work for a one-off data load to MySQL, but in most cases, organizations need to do this periodically merging the data point every day with seamless handling of duplicates. This will need you to write a very sophisticated import tool just for Google Analytics. The above method addresses only one API that is provided by Google. There are many other available APIs from Google which provide different types of data from the Google Analytics engine. An example is a real-time API. All these APIs come with a different output JSON structure and the developers will need to write separate parsers. A solution to all the above problems is to use a completely managed Data Integration Platform like LIKE.TG . Before wrapping up, let’s cover some basics. Prerequisites You will have a much easier time understanding the ways for setting up the Google Analytics to MySQL connection if you have gone through the following aspects: An active Google Analytics account. An active MySQL account. Working knowledge of SQL. Working knowledge of at least one scripting language. Introduction to Google Analytics Google Analytics is the service offered by Google to get complete information about your website and its users. It allows the site owners to measure the performance of their marketing, content, and products. It not only provides unique insights but also helps users deploy machine learning capabilities to make the most of their data. Despite all the unique analysis services provided by Google, it is sometimes required to get the raw clickstream data from your website into the on-premise databases. This helps in creating deeper analysis results by combining the clickstream data with the organization’s customer data and product data. To know more about Google Analytics, visit this link. Introduction to MySQL MySQL is a SQL-based open-source Relational Database Management System. It stores data in the form of tables. MySQL is a platform-independent database, which means you can use it on Windows, Mac OS X, or Linux with ease.

What is Data Warehousing? Data warehousing is the process of collating data from multiple sources in an organization and store it in one place for further analysis, reporting and business decision making. Typically, organizations will have a transactional database that contains information on all day to day activities. Organizations will also have other data sources – third party or internal operations related. Data from all these sources are collated and stored in a data warehouse through an ELT or ETL process. The data model of the warehouse is designed such that, it is possible to combine data from all these sources and make business decisions based on them.In this blog, we will discuss 6 most important factors and data warehouse best practices to consider when building your first data warehouse. Impact of Data Sources Kind of data sources and their format determines a lot of decisions in a data warehouse architecture. Some of the best practices related to source data while implementing a data warehousing solution are as follows. Detailed discovery of data source, data types and its formats should be undertaken before the warehouse architecture design phase. This will help in avoiding surprises while developing the extract and transformation logic. Data sources will also be a factor in choosing the ETL framework. Irrespective of whether the ETL framework is custom-built or bought from a third party, the extent of its interfacing ability with the data sources will determine the success of the implementation. The Choice of Data Warehouse One of the most primary questions to be answered while designing a data warehouse system is whether to use a cloud-based data warehouse or build and maintain an on-premise system. There are multiple alternatives for data warehouses that can be used as a service, based on a pay-as-you-use model. Likewise, there are many open sources and paid data warehouse systems that organizations can deploy on their infrastructure. On-Premise Data Warehouse An on-premise data warehouse means the customer deploys one of the available data warehouse systems – either open-source or paid systems on his/her own infrastructure. There are advantages and disadvantages to such a strategy. Advantages of using an on-premise setup The biggest advantage here is that you have complete control of your data. In an enterprise with strict data security policies, an on-premise system is the best choice. The data is close to where it will be used and latency of getting the data from cloud services or the hassle of logging to a cloud system can be annoying at times. Cloud services with multiple regions support to solve this problem to an extent, but nothing beats the flexibility of having all your systems in the internal network. An on-premise data warehouse may offer easier interfaces to data sources if most of your data sources are inside the internal network and the organization uses very little third-party cloud data. Disadvantages of using an on-premise setup Building and maintaining an on-premise system requires significant effort on the development front. Scaling can be a pain because even if you require higher capacity only for a small amount of time, the infrastructure cost of new hardware has to be borne by the company. Scaling down at zero cost is not an option in an on-premise setup. Cloud Data Warehouse In a cloud-based data warehouse service, the customer does not need to worry about deploying and maintaining a data warehouse at all. The data warehouse is built and maintained by the provider and all the functionalities required to operate the data warehouse are provided as web APIs. Examples for such services are AWS Redshift, Microsoft Azure SQL Data warehouse, Google BigQuery, Snowflake, etc. Such a strategy has its share of pros and cons. Advantages of using a cloud data warehouse: Scaling in a cloud data warehouse is very easy. The provider manages the scaling seamlessly and the customer only has to pay for the actual storage and processing capacity that he uses. Scaling down is also easy and the moment instances are stopped, billing will stop for those instances providing great flexibility for organizations with budget constraints. The customer is spared of all activities related to building, updating and maintaining a highly available and reliable data warehouse. Disadvantages of using a cloud data warehouse The biggest downside is the organization’s data will be located inside the service provider’s infrastructure leading to data security concerns for high-security industries. There can be latency issues since the data is not present in the internal network of the organization. To an extent, this is mitigated by the multi-region support offered by cloud services where they ensure data is stored in preferred geographical regions. The decision to choose whether an on-premise data warehouse or cloud-based service is best-taken upfront. For organizations with high processing volumes throughout the day, it may be worthwhile considering an on-premise system since the obvious advantages of seamless scaling up and down may not be applicable to them.

ETL vs ELT The movement of data from different sources to data warehouse and the related transformation is done through an extract-transform-load or an extract-load-transform workflow. Whether to choose ETL vs ELT is an important decision in the data warehouse design. In an ETL flow, the data is transformed before loading and the expectation is that no further transformation is needed for reporting and analyzing. ETL has been the de facto standard traditionally until the cloud-based database services with high-speed processing capability came in. This meant, the data warehouse need not have completely transformed data and data could be transformed later when the need comes. This way of data warehousing has the below advantages. The transformation logic need not be known while designing the data flow structure. Only the data that is required needs to be transformed, as opposed to the ETL flow where all data is transformed before being loaded to the data warehouse. ELT is a better way to handle unstructured data since what to do with the data is not usually known beforehand in case of unstructured data. As a best practice, the decision of whether to use ETL or ELT needs to be done before the data warehouse is selected. An ELT system needs a data warehouse with a very high processing ability. Download the Cheatsheet on Optimizing Data Warehouse Performance Learn the Best Practices for Data Warehouse Performance Architecture Consideration Designing a high-performance data warehouse architecture is a tough job and there are so many factors that need to be considered. Given below are some of the best practices. Deciding the data model as easily as possible – Ideally, the data model should be decided during the design phase itself. The first ETL job should be written only after finalizing this. At this day and age, it is better to use architectures that are based on massively parallel processing. Using a single instance-based data warehousing system will prove difficult to scale. Even if the use case currently does not need massive processing abilities, it makes sense to do this since you could end up stuck in a non-scalable system in the future. If the use case includes a real-time component, it is better to use the industry-standard lambda architecture where there is a separate real-time layer augmented by a batch layer. ELT is preferred when compared to ETL in modern architectures unless there is a complete understanding of the complete ETL job specification and there is no possibility of new kinds of data coming into the system. Build a Source Agnostic Integration Layer The primary purpose of the integration layers is to extract information from multiple sources. By building a Source Agnostic integration layer you can ensure better business reporting. So, unless the company has a personalized application developed with a business-aligned data model on the back end, opting for a third-party source to align defeats the purpose. Integration needs to align with the business model. ETL Tool Considerations Once the choice of data warehouse and the ETL vs ELT decision is made, the next big decision is about the ETL tool which will actually execute the data mapping jobs. An ETL tool takes care of the execution and scheduling of all the mapping jobs. The business and transformation logic can be specified either in terms of SQL or custom domain-specific languages designed as part of the tool. The alternatives available for ETL tools are as follows Completely custom-built tools – This means the organization exploits open source frameworks and languages to implement a custom ETL framework which will execute jobs according to the configuration and business logic provided. This is an expensive option but has the advantage that the tool can be built to have the best interfacing ability with the internal data sources. Completely managed ETL services – Data warehouse providers like AWS and Microsoft offer ETL tools as well as a service. An example is the AWS glue or AWS data pipeline. Such services relieve the customer of the design, development and maintenance activities and allow them to focus only on the business logic. A limitation is that these tools may have limited abilities to interface with internal data sources that are custom ones or not commonly used.

Identify Why You Need a Data Warehouse Organizations usually fail to implement a Data Lake because they haven’t established a clear business use case for it. Organizations that begin by identifying a business problem for their data, can stay focused on finding a solution. Here are a few primary reasons why you might need a Data Warehouse: Improving Decision Making: Generally, organizations make decisions without analyzing and obtaining the complete picture from their data as opposed to successful businesses that develop data-driven strategies and plans. Data Warehousing improves the efficiency and speed of data access, allowing business leaders to make data-driven strategies and have a clear edge over the competition. Standardizing Your Data: Data Warehouses store data in a standard format making it easier for business leaders to analyze it and extract actionable insights from it. Standardizing the data collated from various disparate sources reduces the risk of errors and improves the overall accuracy. Reducing Costs: Data Warehouses let decision-makers dive deeper into historical data and ascertain the success of past initiatives. They can take a look at how they need to change their approach to minimize costs, drive growth, and increase operational efficiencies. Have an Agile Approach Instead of a Big Bang Approach Among the Data Warehouse Best Practices, having an agile approach to Data Warehousing as opposed to a Big Bang Approach is one of the most pivotal ones. Based on the complexity, it can take anywhere between a few months to several years to build a Modern Data Warehouse. During the implementation, the business cannot realize any value from their investment. The requirements also evolve with time and sometimes differ significantly from the initial set of requirements. This is why a Big Bang approach to Data Warehousing has a higher risk of failure because businesses put the project on hold. Plus, you cannot personalize the Big Bang approach to a specific vertical, industry, or company. By following an agile approach you allow the Data Warehouse to evolve with the business requirements and focus on current business problems. this model is an iterative process in which modern data warehouses are developed in multiple sprints while including the business user throughout the process for continuous feedback. Have a Data Flow Diagram By having a Data Flow Diagram in place, you have a complete overview of where all the business’ data repositories are and how the data travels within the organization in a diagrammatic format. This also allows your employees to agree on the best steps moving forward because you can’t get to where you want to be if you have do not have an inkling about where you are. Define a Change Data Capture (CDC) Policy for Real-Time Data By defining the CDC policy you can capture any changes that are made in a database, and ensure that these changes get replicated in the Data Warehouse. The changes are captured, tracked, and stored in relational tables known as change tables. These change tables provide a view of historical data that has been changed over time. CDC is a highly effective mechanism for minimizing the impact on the source when loading new data into your Data Warehouse. It also does away with the need for bulk load updating along with inconvenient batch windows. You can also use CDC to populate real-time analytics dashboards, and optimize your data migrations. Consider Adopting an Agile Data Warehouse Methodology Data Warehouses don’t have to be monolithic, huge, multi-quarter/yearly efforts anymore. With proper planning aligning to a single integration layer, Data Warehouse projects can be dissected into smaller and faster deliverable pieces that return value that much more quickly. By adopting an agile Data Warehouse methodology, you can also prioritize the Data Warehouse as the business changes. Use Tools instead of Building Custom ETL Solutions With the recent developments of Data Analysis, there are enough 3rd party SaaS tools (hosted solutions) for a very small fee that can effectively replace the need for coding and eliminate a lot of future headaches. For instance, Loading and Extracting tools are so good these days that you can have the pick of the litter for free all the way to tens of thousands of dollars a month. You can quite easily find a solution that is tailored to your budget constraints, support expectations, and performance needs. However, there are various legitimate fears in choosing the right tool, since there are so many SaaS solutions with clever marketing teams behind them. Other Data Warehouse Best Practices Other than the major decisions listed above, there is a multitude of other factors that decide the success of a data warehouse implementation. Some of the more critical ones are as follows. Metadata management – Documenting the metadata related to all the source tables, staging tables, and derived tables are very critical in deriving actionable insights from your data. It is possible to design the ETL tool such that even the data lineage is captured. Some of the widely popular ETL tools also do a good job of tracking data lineage. Logging – Logging is another aspect that is often overlooked. Having a centralized repository where logs can be visualized and analyzed can go a long way in fast debugging and creating a robust ETL process. Joining data – Most ETL tools have the ability to join data in extraction and transformation phases. It is worthwhile to take a long hard look at whether you want to perform expensive joins in your ETL tool or let the database handle that. In most cases, databases are better optimized to handle joins. Keeping the transaction database separate – The transaction database needs to be kept separate from the extract jobs and it is always best to execute these on a staging or a replica table such that the performance of the primary operational database is unaffected. Monitoring/alerts – Monitoring the health of the ETL/ELT process and having alerts configured is important in ensuring reliability. Point of time recovery – Even with the best of monitoring, logging, and fault tolerance, these complex systems do go wrong. Having the ability to recover the system to previous states should also be considered during the data warehouse process design. Conclusion The above sections detail the best practices in terms of the three most important factors that affect the success of a warehousing process – The data sources, the ETL tool and the actual data warehouse that will be used.This includes Data Warehouse Considerations, ETL considerations, Change Data Capture, adopting an Agile methodology, etc. Are there any other factors that you want us to touch upon?

MongoDB is a NoSQL database that stores objects in a JSON-like structure. Because it treats objects as documents, it is usually classified as document-oriented storage. Schemaless databases like MongoDB offer unique versatility because they can store semi-structured data. MySQL, on the other hand, is a structured database with a hard schema. It is a usual practice to use NoSQL databases for use cases where the number of fields will evolve as the development progresses. When the use case matures, organizations will notice the overhead introduced by their NoSQL schema. They will want to migrate the data to hard-structured databases with comprehensive querying ability and predictable query performance. In this article, you will first learn the basics about MongoDB and MySQL and how to easily set up MongoDB to MySQL Integration using the two methods. What is MongoDB? MongoDB is a popular open-source, non-relational, document-oriented database. Instead of storing data in tables like traditional relational databases, MongoDB stores data in flexible JSON-like documents with dynamic schemas, making it easy to store unstructured or semi-structured data. Some key features of MongoDB include: Document-oriented storage: More flexible and capable of handling unstructured data than relational databases. Documents map nicely to programming language data structures. High performance: Outperforms relational databases in many scenarios due to flexible schemas and indexing. Handles big data workloads with horizontal scalability. High availability: Supports replication and automated failover for high availability. Scalability: Scales horizontally using sharding, allowing the distribution of huge datasets and transaction load across commodity servers. Elastic scalability for handling variable workloads. What is MySQL? MySQL is a widely used open-source Relational Database Management System (RDBMS) developed by Oracle. It employs structured query language (SQL) and stores data in tables with defined rows and columns, making it a robust choice for applications requiring data integrity, consistency, and reliability. Some major features that have contributed to MySQL’s popularity over competing database options are: Full support for ACID (Atomicity, Consistency, Isolation, Durability) transactions, guaranteeing accuracy of database operations and resilience to system failures – vital for use in financial and banking systems. Implementation of industry-standard SQL for manipulating data, allowing easy querying, updating, and administration of database contents in a standardized way. Database replication capability enables MySQL databases to be copied and distributed across servers. This facilitates scalability, load balancing, high availability, and fault tolerance in mission-critical production environments. Load Your Data from Google Ads to MySQLGet a DemoTry itLoad Your Data from Salesforce to MySQLGet a DemoTry itLoad Your Data from MongoDB to MySQLGet a DemoTry it Methods to Set Up MongoDB to MySQL Integration There are many ways of loading data from MongoDB to MySQL. In this article, you will be looking into two popular ways. In the end, you will understand each of these two methods well. This will help you to make the right decision based on your use case: Method 1: Manual ETL Process to Set Up MongoDB to MySQL Integration Method 2: Using LIKE.TG Data to Set Up MongoDB to MySQL Integration Prerequisites MongoDB Connection Details MySQL Connection Details Mongoexport Tool Basic understanding of MongoDB command-line tools Ability to write SQL statements Method 1: Using CSV File Export/Import to Convert MongoDB to MySQL MongoDB and MySQL are incredibly different databases with different schema strategies. This means there are many things to consider before moving your data from a Mongo collection to MySQL. The simplest of the migration will contain the few steps below. Step 1: Extract data from MongoDB in a CSV file format Use the default mongoexport tool to create a CSV from the collection. mongoexport --host localhost --db classdb --collection student --type=csv --out students.csv --fields first_name,middle_name,last_name, class,email In the above command, classdb is the database name, the student is the collection name and students.csv is the target CSV file containing data from MongoDB. An important point here is the –field attribute. This attribute should have all the lists of fields that you plan to export from the collection. If you consider it, MongoDB follows a schema-less strategy, and there is no way to ensure that all the fields are present in all the documents. If MongoDB were being used for its intended purpose, there is a big chance that not all documents in the same collection have all the attributes. Hence, while doing this export, you should ensure these fields are in all the documents. If they are not, MongoDB will not throw an error but will populate an empty value in their place. Step 2: Create a student table in MySQL to accept the new data. Use the Create table command to create a new table in MySQL. Follow the code given below. CREATE TABLE students ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, middlename VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, class VARCHAR(30) NOT NULL, email VARCHAR(30) NOT NULL, ) Step 3: Load the data into MySQL Load the data into the MySQL table using the below command. LOAD DATA LOCAL INFILE 'students.csv' INTO TABLE students FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY 'n' (firstname,middlename,lastname,class,email) You have the data from MongoDB loaded into MySQL now. Another alternative to this process would be to exploit MySQL’s document storage capability. MongoDB documents can be directly loaded as a MySQL collection rather than a MySQL table. The caveat is that you cannot use the true power of MySQL’s structured data storage. In most cases, that is why you moved the data to MySQL in the first place. However, the above steps only work for a limited set of use cases and do not reflect the true challenges in migrating a collection from MongoDB to MySQL. Let us look into them in the next section. Limitations of Using the CSV Export/Import Method | Manual setting up Data Structure Difference: MongoDB has a schema-less structure, while MySQL has a fixed schema. This can create an issue when loading data from MongoDB to MySQL, and transformations will be required. Time-Consuming: Extracting data from MongoDB manually and creating a MySQL schema is time-consuming, especially for large datasets requiring modification to fit the new structure. This becomes even more challenging because applications must run with little downtime during such transfers. Initial setup is complex: The initial setup for data transfer between MongoDB and MySQL demands a deep understanding of both databases. Configuring the ETL tools can be particularly complex for those with limited technical knowledge, increasing the potential for errors. A solution to all these complexities will be to use a third-party cloud-based ETL tool like LIKE.TG .LIKE.TG can mask all the above concerns and provide an elegant migration process for your MongoDB collections. Method 2: Using LIKE.TG Data to Set Up MongoDB to MySQL Integration The steps to load data from MongoDB to MySQL using LIKE.TG Data are as follows: Step 1: Configure MongoDB as your Source ClickPIPELINESin theNavigation Bar.

In theAdd Destination page, selectMySQL. In theConfigure yourMySQLDestinationpage, specify the following: LIKE.TG automatically flattens all the nested JSON data coming from MongoDB and automatically maps it to MySQL destination without any manual effort.For more information on integrating MongoDB to MySQL, refer to LIKE.TG documentation. Here are more reasons to try LIKE.TG to migrate from MongoDB to MySQL: Use Cases of MongoDB to MySQL Migration Structurization of Data: When you migrate MongoDB to MySQL, it provides a framework to store data in a structured manner that can be retrieved, deleted, or updated as required. To Handle Large Volumes of Data: MySQL’s structured schema can be useful over MongoDB’s document-based approach for dealing with large volumes of data, such as e-commerce product catalogs. This can be achieved if we convert MongoDB to MySQL. MongoDB compatibility with MySQL Although both MongoDB and MySQL are databases, you cannot replace one with the other. A migration plan is required if you want to switch databases. These are a few of the most significant variations between the databases. Querying language MongoDB has a different approach to data querying than MySQL, which uses SQL for the majority of its queries. You may use aggregation pipelines to do sophisticated searches and data processing using the MongoDB Query API. It will be necessary to modify the code in your application to utilize this new language. Data structures The idea that MongoDB does not enable relationships across data is a bit of a fiction. Nevertheless, you may wish to investigate other data structures to utilize all of MongoDB’s capabilities fully. Rather than depending on costly JOINs, you may embed documents directly into other documents in MongoDB. This kind of modification results in significantly quicker data querying, less hardware resource usage, and data returned in a format that is familiar to software developers.

LIKE.TG provides an easy-to-use data integration platform that works by building an automated pipeline in just two interactive steps: Step 1: Configure Google Sheets as a source, by entering the Pipeline Name and the spreadsheet you wish to replicate. Perform the following steps to configure Google Sheets as a Source in your Pipeline: Click PIPELINES in the Navigation Bar. Click + CREATE in the Pipelines List View. In the Select Source Type page, select Google Sheets. In the Configure your Google Sheets account page, to select the authentication method for connecting to Google Sheets, do one of the following: To connect with a User Account, do one of the following: Select a previously configured account and click CONTINUE. Click + ADD GOOGLE SHEETS ACCOUNT and perform the following steps to configure an account: Select the Google account associated with your Google Sheets data. Click Allow to authorize LIKE.TG to access the data. To connect with a Service Account, do one of the following: Select a previously configured account and click CONTINUE. Click the attach icon () to upload the Service Account Key and click CONFIGURE GOOGLE SHEETS ACCOUNT.Note: LIKE.TG supports only JSON format for the key file. In the Configure your Google Sheets Source page, specify the Pipeline Name, Sheets, Custom Header Row. Click TEST CONTINUE. Proceed to configuring the data ingestion and setting up the Destination. Step 2: Create and Configure your Snowflake Warehouse LIKE.TG provides you with a ready-to-use script to configure the Snowflake warehouse you intend to use as the Destination. Follow these steps to run the script: Log in to your Snowflake account. In the top right corner of the Worksheets tab, click the + icon to create a new worksheet. Paste the script in the worksheet. The script creates a new role for LIKE.TG in your Snowflake Destination. Keeping your privacy in mind, the script grants only the bare minimum permissions required by LIKE.TG to load the data in your Destination. Replace the sample values provided in lines 2-7 of the script with your own to create your warehouse. These are the credentials that you will be using to connect your warehouse to LIKE.TG . You can specify a new warehouse, role, and or database name to create these now or use pre-existing ones to load data into. Press CMD + A (Mac) or CTRL + A (Windows) inside the worksheet area to select the script. Press CMD+return (Mac) or CTRL + Enter (Windows) to run the script. Once the script runs successfully, you can use the credentials from lines 2-7 of the script to connect your Snowflake warehouse to LIKE.TG . Step 3: Complete Google Sheets to Snowflake migration by providing your destination name, account name, region of your account, database username and password, database and schema name, and the Data Warehouse name. And LIKE.TG automatically takes care of the rest. It’s just that simple.You are now ready to start migrating data from Google Sheets to Snowflake in a hassle-free manner! You can also integrate data from numerous other free data sources like Google Sheets, Zendesk, etc. to the desired destination of your choice such as Snowflake in a jiff. LIKE.TG is also much faster, thanks to its highly optimized features and architecture. Some of the additional features you can also enjoy with LIKE.TG are: Transformations– LIKE.TG provides preload transformations through Python code. It also allows you to run transformation code for each event in the pipelines you set up. You need to edit the event object’s properties received in the transform method as a parameter to carry out the transformation. LIKE.TG also offers drag-and-drop transformations like Date and Control Functions, JSON, and Event Manipulation to name a few. These can be configured and tested before putting them to use. Monitoring and Data Management – LIKE.TG automatically manages your data loads and ensures you always have up-to-date and accurate data in Snowflake. Automatic Change Data Capture – LIKE.TG performs incremental data loads automatically through a number of in-built Change Data Capture mechanisms. This means, as and when data on Google Sheets changes, they are loaded onto Snowflake in real time. It just took us 2 weeks to completely transform from spreadsheets to a modern data stack. Thanks to LIKE.TG that helped us make this transition so smooth and quick. Now all the stakeholders of our management, sales, and marketing team can easily build and access their reports in just a few clicks. – Matthew Larner, Managing Director, ClickSend Method 2: Using Migration Scripts to Connect Google Sheets to Snowflake To migrate your data from Google Sheets to Snowflake, you may opt for a custom-built data migration script to get the job done.We will demonstrate this process in the next paragraphs. To proceed, you will need the following requirements. Step 1: Setting Up Google Sheets API Access for Google Sheets As a first step, you would need to set up Google Sheets API access for the affected Google Sheets. Start by doing the following: 1. Log in to the Google account that owns the Google Sheets 2. Point your browser to the Google Developer Console (copy and paste the following in your browser: console.developers.google.com) 3. After the console loads create a project by clicking the “Projects” dropdown and then clicking “New Project“ 4. Give your project a name and click “Create“ 5. After that, click “Enable APIs and Services“ 6. Search for “Google Sheets API” in the search bar that appears and select it 7. Click “Enable” to enable the Google Sheets API 8. Click on the “Credentials” option on the left navbar in the view that appears, then click “Create Credentials“, and finally select “Service Account“ 9. Provide a name for your service account. You will notice it generates an email format for the Service Account ID. In my example in the screenshot below, it is “[email protected]”. Take note of this value. The token “migrate-268012” is the name of the project I created while “gsheets-migration” is the name of my service account. In your case, these would be your own supplied values. 10. Click “Create” and fill out the remaining optional fields. Then click “Continue“ 11. In the view that appears, click “Create Key“, select the “JSON” option and click “Create” to download your key file (credentials). Please store it in a safe place. We will use this later when setting up our migration environment. 12. Finally, click “Done“. At this point, all that remains for the Google Sheets setup is the sharing of all the Google Sheets you wish to migrate with the email-format Service Account ID mentioned in step 9 above. Note: You can copy your Service Account ID from the “client-email” field of the credential file you downloaded. For this demonstration, I will be migrating a sheet called “data-uplink-logs” shown in the screenshot below. I will now share it with my Service Account ID:Click “Share” on the Google sheet, paste in your Service Account ID, and click “Send“. Repeat this process for all sheets you want to migrate. Ignore any “mail delivery subsystem failure” notifications you receive while sharing the sheets, as your Service Account ID is not designed to operate as a normal email address. Step 2: Configuring Target Database in Snowflake We’re now ready to get started on the Snowflake side of the configuration process, which is simpler. To begin, create a Snowflake account. Creating an account furnishes you with all the credentials you will need to access Snowflake from your migration script. Specifically: After creating your account, you will be redirected to your Cloud Console which will open up in your browser During the account creation process, you would have specified your chosen username and password. You would have also selected your preferred AWS region, which will be part of your account. Your Snowflake account is of the form <Your Account ID>.<AWS Region> and your Snowflake cloud console URL will be of the form https://<Your Account ID>.<AWS Region>.snowflakecomputing.com/ Prepare and store a JSON file with these credentials. It will have the following layout: { "user": "<Your Username>", "account": "<Your Account ID>.<AWS Region>", "password": "<Your Password>" } After storing the JSON file, take some time to create your target environment on Snowflake using the intuitive User Interface. You are initially assigned a Data Warehouse called COMPUTE_WH so you can go ahead and create a Database and tables in it. After providing a valid name for your database and clicking “Finish“, click the “Grant Privileges” button which will show the form in the screenshot below. Select the “Modify” privilege and assign it to your schema name (which is “PUBLIC” by default). Click “Grant“. Click “Cancel” if necessary, after that, to return the main view. The next step is to add a table to your newly created database. You do this by clicking the database name on the left display and then clicking on the “Create Table” button. This will pop up the form below for you to design your table: After designing your table, click “Finish” and then click on your table name to verify that your table was created as desired: Finally, open up a Worksheet pane, which will allow you to run queries on your table. Do this by clicking on the “Worksheets” icon, and then clicking on the “+” tab. You can now select your database from the left pane to start running queries. We will run queries from this view to verify that our data migration process is correctly writing our data from the Google sheet to this table. We are now ready to move on to the next step. Step 3: Preparing a Migration Environment on Linux Server In this step, we will configure a migration environment on our Linux server. SSH into your Linux instance. I am using a remote AWS EC2 instance running Ubuntu, so my SSH command is of the form ssh -i <keyfile>.pem ubuntu@<server_public_IP> Once in your instance, run sudo apt-get update to update the environment Next, create a folder for the migration project and enter it sudo mkdir migration-test; cd migration-test It’s now time to clone the migration script we created for this post: sudo git clone https://github.com/cmdimkpa/Google-Sheets-to-Snowflake-Data-Migration.git Enter the project directory and view contents with the command: cd Google-Sheets-to-Snowflake-Data-Migration; ls This reveals the following files: googlesheets.json: copy your saved Google Sheets API credentials into this file. snowflake.json: likewise, copy your saved Snowflake credentials into this file. migrate.py: this is the migration script. Using the Migration Script Before using the migration script (a Python script), we must ensure the required libraries for both Google Sheets and Snowflake are available in the migration environment. Python itself should already be installed – this is usually the case for Linux servers, but check and ensure it is installed before proceeding. To install the required packages, run the following commands: sudo apt-get install -y libssl-dev libffi-dev pip install --upgrade snowflake-connector-python pip install gspread oauth2client PyOpenSSL At this point, we are ready to run the migration script. The required command is of the form: sudo python migrate.py <Source Google Sheet Name> <Comma-separated list of columns in the Google Sheet to Copy> <Number of rows to copy each run> <Snowflake target Data Warehouse> <Snowflake target Database> <Snowflake target Table> <Snowflake target table Schema> <Comma-separated list of Snowflake target table fields> <Snowflake account role> For our example process, the command becomes: sudo python migrate.py data-uplink-logs A,B,C,D 24 COMPUTE_WH TEST_GSHEETS_MIGRATION GSHEETS_MIGRATION PUBLIC CLIENT_ID,NETWORK_TYPE,BYTES,UNIX_TIMESTAMP SYSADMIN To migrate 24 rows of incremental data (each run) from our test Google Sheet data-uplink-logs to our target Snowflake environment, we simply run the command above. The following is a screenshot of what follows: The reason we migrate only 24 rows at a time is to beat the rate limit for the free tier of the Google Sheets API. Depending on your plan, you may not have this restriction. Step 4: Testing the Migration Process To test that the migration ran successfully, we simply go to our Snowflake Worksheet which we opened earlier, and run the following SQL query: SELECT * FROM TEST_GSHEETS_MIGRATION.PUBLIC.GSHEETS_MIGRATION Indeed, the data is there. So the data migration effort was successful. Step 5: Run CRON Jobs As a final step, run cron jobs as required to have the migrations occur on a schedule. We cannot cover the creation of cron jobs here, as it is beyond the scope of this post. This concludes the first approach! I hope you were as excited reading that as I was, writing it. It’s been an interesting journey, now let’s review the drawbacks of this approach. Limitations of using Migration Scripts to Connect Google Sheets to Snowflake The migration script approach to connect google sheets to Snowflake works well, but has the following drawbacks: This approach would need to pull out a few engineers to set up and test this infrastructure. Once built, you would also need to have a dedicated engineering team that can constantly monitor the infra and provide immediate support if and when something breaks. Aside from the setup process which can be intricate depending on experience, this approach creates new requirements such as: The need to monitor the logs and ensure the uptime of the migration processes. Fine-tuning of the cron jobs to ensure optimal data transmission with respect to the data inflow rates of the different Google sheets, any Google Sheet API rate limits, and the latency requirements of the reporting or analytics processes running on Snowflake or elsewhere. Download the Cheatsheet on How to Set Up ETL to Snowflake Learn the best practices and considerations for setting up high-performance ETL to Snowflake Method 3: Connect Google Sheets to Snowflake Using Python In this method, you will use Python to load data from Google Sheets to Snowflake. To do this, you will have to enable public access to your Google Sheets. You can do this by going to File>> Share >> Publish to web. After publishing to web, you will see a link in the format of https://docs.google.com/spreadsheets/d/{your_google_sheets_id}/edit#gid=0 You would need to install certain libraries in order to read this data, transform it into a dataframe, and write to Snowflake. Snowflake.connector and Pyarrow are the other two, while Pandas is the first. Installing pandas may be done with pip install pandas. The command pip install snowflake-connector-python may also be used to install Snowflake connector. The command pip install pyarrow may be used to install Pyarrow. You may use the following code to read the data from your Google Sheets. import pandas as pd data=pd.read_csv(f'https://docs.google.com/spreadsheets/d/{your_google_sheets_id}/pub?output=csv') In the code above, you will replace {your_google_sheets_id} with the id from your spreadsheet. You can preview the data by running the command data.head() You can also check out the number of columns and records by running data.shape Setting up Snowflake login credentials You will need to set up a data warehouse, database, schema, and table on your Snowflake account. Data loading in Snowflake You would need to utilize the Snowflake connection that was previously installed in Python in order to import the data into Snowflake. When you run write_to_snowflake(data), you will ingest all the data into your Snowflake data warehouse. Disadvantages Of Using ETL Scripts There are a variety of challenges and drawbacks when integrating data from sources like Google Sheets to Snowflake using ETL (Extract, Transform, Load) procedures, especially for businesses with little funding or experience. Price is the primary factor to be considered. Implementation and upkeep of the ETL technique can be expensive. It demands investments in personnel with the necessary skills to efficiently design, develop, and oversee these processes in addition to technology. Complexity is an additional problem. ETL processes may be intricate and challenging to configure properly. Companies without the necessary expertise may find it difficult to properly manage data conversions and interfaces. ETL processes can have limitations on scalability and flexibility. They might not be able to handle unstructured data well or provide real-time data streams, which makes them inappropriate.

It allows users to stream data from Kafka straight into BigQuery with sub-minute latency through its underlying framework. Kafka connect gives users the incentive of making use of existing connector implementations so you don’t need to draw up new connections when moving new data. Kafka Connect provides a ‘SINK’ connector that continuously consumes data from consumed Kafka topics and streams to external storage location in seconds. It also has a ‘SOURCE’ connector that ingests databases as a whole and streams table updates to Kafka topics. There is no inbuilt connector for Google BigQuery in Kafka Connect. Hence, you will need to use third-party tools such as Wepay. When making use of this tool, Google BigQuery tables can be auto-generated from the AVRO schema seamlessly. The connector also aids in dealing with schema updates. As Google BigQuery streaming is backward compatible, it enables users to easily add new fields with default values, and steaming will continue uninterrupted. Using Kafka Connect, the data can be streamed and ingested into Google BigQuery in real-time. This, in turn, gives users the advantage to carry out analytics on the fly. Limitations of Streaming with Kafka Connect In this method, data is partitioned only by the processing time. Streaming Data with Apache Beam Apache Beam is an open-source unified programming model that implements batch and stream data processing jobs that run on a single engine. The Apache Beam model helps abstract all the complexity of parallel data processing. This allows you to focus on what is required of your Job not how the Job gets executed. One of the major downsides of streaming with Kafka Connect is that it can only ingest data by the processing time which can lead to data arriving in the wrong partition. Apache Beam resolves this issue as it supports both batch and stream data processing. Apache Beam has a supported distributed processing backend called Cloud Data Flow that executes your code as a cloud job making it fully managed and auto-scaled. The number of workers is fully elastic as it changes according to your current workload and the cost of execution is altered concurrently. Limitations of Streaming Data with Apache Beam Apache Beam incurs an extra cost for running managed workers. Apache Beam is not a part of the Kafka ecosystem. LIKE.TG supportsboth Batch Load Streaming Load for the Kafka to BigQuery use case and providesa no-code, fully-managed minimal maintenancesolutionfor this use case. Step 2: Ingesting Data to BigQuery Before you start streaming in from Kafka to BigQuery, you need to check the following boxes: Make sure you have the Write access to the dataset that contains your destination table to prevent subsequent errors when streaming. Check the quota policy for streaming data on BigQuery to ensure you are not in violation of any of the policies. Ensure that billing is enabled for your GCP (Google Cloud Platform) account. This is because streaming is not available for the free tier of GCP, hence if you want to stream data into Google BigQuery you have to make use of the paid tier. Now, let us discuss the methods to ingest our streamed data from Kafka to BigQuery. The following approaches are covered in this post: Streaming with BigQuery API Batch Loading into Google Cloud Storage (GCS) Streaming with BigQuery API The Google BigQuery API is a data platform for users to manage, create, share and query data. It supports streaming data directly into Google BigQuery with a quota of up 100K rows per project. Real-time data streaming on Google BigQuery API costs $0.05 per GB. To make use of Google BigQuery API, it has to be enabled on your account. To enable the API: Ensure that you have a project created. In the GCP Console, click on the hamburger menu and select APIs and services and click on the dashboard. In the API and services window, select enable API and Services. A search query will pop up. Enter Google BigQuery. Two search results of Google BigQuery Data Transfer and Google BigQuery API will pop up. Select both of them and enable them. With Google BigQuery API enabled, the next step would be to move the data from Apache Kafka through a stream processing framework like Kafka streams into Google BigQuery. Kafka Streams is an open-source library for building scalable streaming applications on top of Apache Kafka. Kafka Streams allow users to execute their code as a regular Java application. The pipeline flows from an ingested Kafka topic and some filtered rows through streams from Kafka to BigQuery. It supports both processing time and event time partitioning models. Limitations of Streaming with BigQuery API Though streaming with the Google BigQuery API gives complete control over your records you have to design a robust system to enable it to scale successfully. You have to handle all streaming errors and downsides independently. Batch Loading Into Google Cloud Storage (GCS) To use this technique you could make use of Secor. Secor is a tool designed to deliver data from Apache Kafka into object storage systems such as GCS and Amazon S3. From GCS we then load the data into Google BigQuery using either a load job, manually via the BigQuery UI, or through Google BigQuery’s command line Software Development Kit (SDK). Limitations of Batch Loading in GCS Secor lacks support for AVRO input format, this forces you to always use a JSON-based input format. This is a two-step process that can lead to latency issues. This technique does not stream data in real-time. This becomes a blocker in real-time analysis for your business. This technique requires a lot of maintenance to keep up with new Kafka topics and fields. To update these changes you would need to put in the effort to manually update the schema in the Google BigQuery table. Method 3: Using the Kafka to BigQuery Connector to Move Data from Apache Kafka to BigQuery The Kafka BigQuery connector is handy to stream data into BigQuery tables. When streaming data from Apache Kafka topics with registered schemas, the sink connector creates BigQuery tables with appropriate BigQuery table schema, which is based on the Kafka scheme information for the topic. Here are some limitations associated with the Kafka Connect BigQuery Sink Connector: No support for schemas with floating fields with NaN or +Infinity values. No support for schemas with recursion. If you configure the connector with upsertEnabled or deleteEnabled, it doesn’t support Single Message Transformations modifying the topic name. Need for Kafka to BigQuery Migration While you can use the Kafka platform to build real-time data pipelines and applications, you can use BigQuery to modernize your IT landscape, while meeting your growing analytics needs. Connecting Kafka to BigQuery allows real-time data processing for analyzing and acting on data as it is generated. This enables you to obtain valuable insights and faster decision-making. Common use case for this is in the finance industry, where it is possible to identify fraudulent activities with real-time data processing. Yet another need for migrating Kafka to BigQuery is scalability. As both platforms are highly scalable, you can handle large data volumes without any performance issues. Scaling your data processing systems for growing data volumes can be done with ease since Kafka can handle millions of messages per second while BigQuery can handle petabytes of data. Another need for Kafka connect BigQuery is its cost-effectiveness factor. Kafka being an open-source platform won’t include any licensing costs; the pay-as-you-go pricing model of BigQuery means you only need to pay for the data processed. Integrating both platforms requires you to only pay for the data that is processed and analyzed, helping reduce overall costs. Conclusion This article provided you with a step-by-step guide on how you can set up Kafka to BigQuery connection using Custom Script or using LIKE.TG . However, there are certain limitations associated with the Custom Script method. You will need to implement it manually, which will consume your time resources and is error-prone.

Integrate you data seamlessly [email protected]"> No credit card required Method 2: Manual ETL Process to Set Up Microsoft SQL Server to BigQuery Integration The steps to execute the custom code are as follows: Step 1: Export the Data from SQL Server using SQL Server Management Studio (SSMS) Step 2: Upload to Google Cloud Storage Step 3: Upload to BigQuery from Google Cloud Storage (GCS) Step 4: Update the Target Table in BigQuery Step 1: Export the Data from SQL Server using SQL Server Management Studio (SSMS) SQL Server Management Studio(SSMS) is a free tool built by Microsoft to enable a coordinated environment for managing any SQL infrastructure. SSMS is used to query, design, and manage your databases from your local machine. We are going to be using the SSMS to extract our data in Comma Separated Value(CSV) format in the steps below. Install SSMS if you don’t have it on your local machine. You can install it here. Open SSMS and connect to a Structured Query Language (SQL) instance. From the object explorer window, select a database and right-click on the Tasks sub-menu, and choose the Export data option. The welcome page of the Server Import and Export Wizard will be opened. Click the Next icon to proceed to export the required data. You will see a window to choose a data source. Select your preferred data source. In the Server name dropdown list, select a SQL Server instance. In the Authentication section select authentication for the data source connection. Next, from the Database drop-down box, select a database from which data will be copied. Once you have filled the drop-down list select ‘Next‘. The next window is the choose the destination window. You will need to specify the location from which the data will be copied in the SQL server. Under the destination, the drop-down box selects the Flat File destination item. In the File name box, establish the CSV file where the data from the SQL database will be exported to and select the next button. The next window you will see is the Specify Table Copy or Query window, choose the Copy data from one or more tables or views to get all the data from the table. Next, you’d see a Configure Flat File Destination window, select the table from the source table to export the data to the CSV file you specified earlier. At this point your file would have been exported, to view the exported file click on preview. To have a sneak peek of the data you just exported. Complete the exportation process by hitting ‘Next‘. The save and run package window will pop up, click on ‘Next‘. The Complete Wizard window will appear next, it will give you an overview of all the choices you made during the exporting process. To complete the exportation process, hit on ‘Finish‘. The exported CSV file will be found in Local Drive, where you specified for it to be exported. Step 2: Upload to Google Cloud Storage After completing the exporting process to your local machine, the next step in SQL Server to BigQuery is to transfer the CSV file to Google Cloud Storage(GCS). There are various ways of achieving this, but for the purpose of this blog post, let’s discuss the following methods. Method 1: Using Gsutil gsutil is a GCP tool that uses Python programming language. It gives you access to GCS from the command line. To initiate gsutil follow this quickstart link. gsutil provides a unique way to upload a file to GCS from your local machine. To create a bucket in which you copy your file to: gsutil mb gs://my-new-bucket The new bucket created is called “my-new-bucket“. Your bucket name must be globally unique. If successful the command returns: Creating gs://my-new-bucket/... To copy your file to GCS: gsutil cp export.csv gs://my-new-bucket/destination/export.csv In this command, “export.csv” refers to the file you want to copy. “gs://my-new-bucket” represents the GCS bucket you created earlier. Finally, “destination/export.csv” specifies the destination path and filename in the GCS bucket where the file will be copied to. Integrate from MS SQL Server to BigQueryGet a DemoTry itIntegrate from MS SQL Server to SnowflakeGet a DemoTry it Method 2: Using Web Console The web console is another alternative you can use to upload your CSV file to the GCS from your local machine. The steps to use the web console are outlined below. First, you will have to log in to your GCP account. Toggle on the hamburger menu which displays a drop-down menu. Select Storage and click on the Browser on the left tab. In order to store the file that you would upload from your local machine, create a new bucket. Make sure the name chosen for the browser is globally unique. The bucket you just created will appear on the window, click on it and select upload files. This action will direct you to your local drive where you will need to choose the CSV file you want to upload to GCS. As soon as you start uploading, a progress bar is shown. The bar disappears once the process has been completed. You will be able to find your file in the bucket. Step 3: Upload Data to BigQuery From GCS BigQuery is where the data analysis you need will be carried out. Hence you need to upload your data from GCS to BigQuery. There are various methods that you can use to upload your files from GCS to BigQuery. Let’s discuss 2 methods here: Method 1: Using the Web Console UI The first point of call when using the Web UI method is to select BigQuery under the hamburger menu on the GCP home page. Select the “Create a new dataset” icon and fill in the corresponding drop-down menu. Create a new table under the data set you just created to store your CSV file. In the create table page –> in the source data section: Select GCS to browse your bucket and select the CSV file you uploaded to GCS – Make sure your File Format is set to CSV. Fill in the destination tab and the destination table. Under schema, click on the auto-detect schema. Select create a table. After creating the table, click on the destination table name you created to view your exported data file. Using Command Line Interface, the Activate Cloud Shell icon shown below will take you to the command-line interface. You can also use the auto-detect feature to specify your schema. Your schema can be specified using the Command-Line. An example is shown below bq load --autodetect --source_format=CSV --schema=schema.json your_dataset.your_table gs://your_bucket/your_file.csv In the above example, schema.json refers to the file containing the schema definition for your CSV file. You can customize the schema by modifying the schema.json file to match the structure of your data. There are 3 ways to write to an existing table on BigQuery. You can make use of any of them to write to your table. Illustrations of the options are given below 1. Overwrite the data To overwrite the data in an existing table, you can use the --replace flag in the bq command. Here’s an example code: bq load --replace --source_format=CSV your_dataset.your_table gs://your_bucket/your_file.csv In the above code, the --replace flag ensures that the existing data in the table is replaced with the new data from the CSV file. 2. Append the table To append data to an existing table, you can use the --noreplace flag in the bq command. Here’s an example code: bq load --noreplace --source_format=CSV your_dataset.your_table gs://your_bucket/your_file.csv The --noreplace flag ensures that the new data from the CSV file is appended to the existing data in the table. 3. Add a new field to the target table. An extra field will be added to the schema. To add a new field (column) to the target table, you can use the bq update command and specify the schema changes. Here’s an example code: bq update your_dataset.your_table --schema schema.json In the above code, schema.json refers to the file containing the updated schema definition with the new field. You need to modify the schema.json file to include the new field and its corresponding data type. Please note that these examples assume you have the necessary permissions and have set up the required authentication for interacting with BigQuery. Step 4: Update the Target Table in BigQuery GCS acts as a staging area for BigQuery, so when you are using Command-Line to upload to BigQuery, your data will be stored in an intermediate table. The data in the intermediate table will need to be updated for the effect to be shown in the target table. There are two ways to update the target table in BigQuery. Update the rows in the final table and insert new rows from the intermediate table. UPDATE final_table t SET t.value = s.value FROM intermediate_data_table s WHERE t.id = s.id; INSERT INTO final_table (id, value) SELECT id, value FROM intermediate_data_table WHERE id NOT IN (SELECT id FROM final_table); In the above code, final_table refers to the name of your target table, and intermediate_data_table refers to the name of the intermediate table where your data is initially loaded. 2. Delete all the rows from the final table which are in the intermediate table. DELETE FROM final_table WHERE id IN (SELECT id FROM intermediate_data_table); In the above code, final_table refers to the name of your target table, and intermediate_data_table refers to the name of the intermediate table where your data is initially loaded. Please make sure to replace final_table and intermediate_data_table with the actual table names, you are working with. This marks the completion of SQL Server to BigQuery connection. Now you can seamlessly sync your CSV files into GCP bucket in order to integrate SQL Server to BigQuery and supercharge your analytics to get insights from your SQL Server database. Limitations of Manual ETL Process to Set Up Microsoft SQL Server to BigQuery Integration Businesses need to put systems in place that will enable them to gain the insights they need from their data. These systems have to be seamless and rapid. Using custom ETL scripts to connect MS SQL Server to BigQuery has the followinglimitations that will affect the reliability and speed of these systems: Writing custom code is only ideal if you’re looking to move your data once from Microsoft SQL Server to BigQuery. Custom ETL code does not scale well with stream and real-time data. You will have to write additional code to update your data. This is far from ideal. When there’s a need to transform or encrypt your data, custom ETL code fails as it will require you to add additional processes to your pipeline. Maintaining and managing a running data pipeline such as this will need you to invest heavily in engineering resources. BigQuery does not ensure data consistency for external data sources, as changes to the data may cause unexpected behavior while a query is running. The data set’s location must be in the same region or multi-region as the Cloud Storage Bucket. CSV files cannot contain nested or repetitive data since the format does not support it. When utilizing a CSV, including compressed and uncompressed files in the same load job is impossible. The maximum size of a gzip file for CSV is 4 GB. While writing code to move data from SQL Server to BigQuery looks like a no-brainer, in the beginning, the implementation and management are much more nuanced than that. The process has a high propensity for errors which will, in turn, have a huge impact on the data quality and consistency. Benefits of Migrating your Data from SQL Server to BigQuery Integrating data from SQL Server to BigQuery offers several advantages. Here are a few usage scenarios: Advanced Analytics: The BigQuery destination’s extensive data processing capabilities allow you to run complicated queries and data analyses on your SQL Server data, deriving insights that would not be feasible with SQL Server alone. Data Consolidation: If you’re using various sources in addition to SQL Server, synchronizing to a BigQuery destination allows you to centralize your data for a more complete picture of your operations, as well as set up a change data collection process to ensure that there are no discrepancies in your data again. Historical Data Analysis: SQL Server has limitations with historical data. Syncing data to the BigQuery destination enables long-term data retention and study of historical trends over time. Data Security and Compliance: The BigQuery destination includes sophisticated data security capabilities. Syncing SQL Server data to a BigQuery destination secures your data and enables comprehensive data governance and compliance management. Scalability: The BigQuery destination can manage massive amounts of data without compromising speed, making it a perfect solution for growing enterprises with expanding SQL Server data.

Introduction to MySQL MySQL is an open-source relational database management system or RDMS, and it is managed using Structured Query Language or SQL, hence its name. MySQL was originally developed and owned by Swedish company MySQL AB, but Sun Microsystems acquired MySQL AB in 2008. In turn, Sun Microsystems was then bought by Oracle two years later, making them the present owners of MySQL. MySQL is a very popular database program that is used in several equally popular systems such as the LAMP stack (Linux, Apache, MySQL, Perl/PHP/Python), Drupal, and WordPress, just to name a few, and is used by many of the largest and most popular websites, including Facebook, Flickr, Twitter, and Youtube. MySQL is also incredibly versatile as it works on various operating systems and system platforms, from Microsoft Windows to Apple MacOS.

Sync Data from Shopify to MySQLGet a DemoTry itSync Data from Shopify to MS SQL ServerGet a DemoTry it Method 2: Using Custom ETL Code to connect Shopify to MySQL Shopify provides two options to access its product and sales data: Use the export option in the Shopify reporting dashboard: This method provides a simple click-to-export function that allows you to export products, orders, or customer data into CSV files. The caveat here is that this will be a completely manual process and there is no way to do this programmatically. Use Shopify rest APIs to access data: Shopify APIs provide programmatic access to products, orders, sales, and customer data. APIs are subject to throttling for higher request rates and use a leaky bucket algorithm to contain the number of simultaneous requests from a single user. The leaky bucket algorithm works based on the analogy of a bucket that leaks at the bottom. The leak rate is the number of requests that will be processed simultaneously and the size of the bucket is the number of maximum requests that can be buffered. Anything over the buffered request count will lead to an API error informing the user of the request rate limit in place. Let us now move into how data can be loaded to MySQL using each of the above methods: Step 1: Using Shopify Export Option Step 2: Using Shopify REST APIs to Access Data Step 1: Using Shopify Export Option The first method provides simple click-and-export solutions to get the product, orders, and customer data into CSV. This CSV can then be used to load to a MySQL instance. The below steps detail how Shopify customers’ data can be loaded to MySQL this way. Go to Shopify admin and go to the customer’s tab. Click Export. Select whether you want to export all customers or a specified list of customers. Shopify allows you to select or search customers if you only want to export a specific list. After selecting customers, select ‘plain CSV’ as the file format. Click Export Customers and Shopify will provide you with a downloadable CSV file. Login to MySQL and use the below statement to create a table according to the Shopify format. CREATE TABLE customers ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, firstname VARCHAR(30) NOT NULL, lastname VARCHAR(30) NOT NULL, email VARCHAR(50), company VARCHAR(50), address1 VARCHAR(50), address2 VARCHAR(50), city VARCHAR(50), province VARCHAR(50), province_code VARCHAR(50), country VARCHAR(50), country_code VARCHAR(50), zip VARCHAR(50), phone VARCHAR(50), accepts_markting VARCHAR(50), total_spent DOUBLE, email VARCHAR(50), total_orders INT, tags VARCHAR(50), notes VARCHAR(50), tax_exempt VARCHAR(50) Load data using the following command: LOAD DATA INFILE'customers.csv' INTO TABLE customers FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY 'rn' IGNORE 1 LINES Now, that was very simple. But, the problem here is that this is a manual process, and programmatically doing this is impossible. If you want to set up a continuous syncing process, this method will not be helpful. For that, we will need to use the Shopify APIs. Step 2: Using Shopify REST APIs to Access Data Shopify provides a large set of APIs that are meant for building applications that interact with Shopify data. Our focus today will be on the product APIs allowing users to access all the information related to products belonging to the specific user account. We will be using the Shopify private apps mechanism to interact with APIs. Private Apps are Shopify’s way of letting users interact with only a specific Shopify store. In this case, authentication is done by generating a username and password from the Shopify Admin. If you need to build an application that any Shopify store can use, you will need a public app configuration with OAuth authentication. Before beginning the steps, ensure you have gone to Shopify Admin and have access to the generated username and password. Once you have access to the credential, accessing the APIs is very easy and is done using basic HTTP authentication. Let’s look into how the most basic API can be called using the generated username and password. curl --user:password GET https://shop.myshopify.com/admin/api/2019-10/shop.json To get a list of all the products in Shopify use the following command: curl --user user:password GET /admin/api/2019-10/products.json?limit=100 Please note this endpoint is paginated and will return only a maximum of 250 results per page. The default pagination limit is 50 if the limit parameter is not given. From the initial response, users need to store the id of the last product they received and then use it with the next request to get to the next page: curl --user user:password GET /admin/api/2019-10/products.json?limit=100since_id=632910392 -o products.json Where since_id is the last product ID that was received on the previous page. The response from the API is a nested JSON that contains all the information related to the products such as title, description, images, etc., and more importantly, the variants sub-JSON which provides all the variant-specific information like barcode, price,inventory_quantity, and much more information. Users need to parse this JSON output and convert the JSON file into a CSV file of the required format before loading it to MySQL. For this, we are using the Linux command-line utility called jq. You can read more about this utility here. For simplicity, we are only extracting the id, product_type, and product title from the result. Assuming your API response is stored in products.json Cat products.json | jq '.data[].headers | [.id .product_type product_title] | join(", ")' >> products.csv Please note you will need to write complicated JSON parsers if you need to retrieve more fields. Once the CSV files are obtained, create the required MYSQL command beforehand and load data using the ‘LOAD DATA INFILE’ command shown in the previous section. LOAD DATA INFILE'products.csv' INTO TABLE customers FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY 'rn' ; Now you have your Shopify product data in your MySQL. Limitations of Using Custom ETL Code to Connect Shopify to MySQL Shopify provides two easy methods to retrieve the data into files. But, both these methods are easy only when the requests are one-off and the users do not need to execute them continuously in a programmatic way. Some of the limitations and challenges that you may encounter are as follows: The above process works fine if you want to bring a limited set of data points from Shopify to MySQL. You will need to write a complicated JSON parser if you need to extract more data points This approach fits well if you need a one-time or batch data load from Shopify to MySQL. In case you are looking at real-time data sync from Shopify to MySQL, the above method will not work. An easier way to accomplish this would be using a fully-managed data pipeline solution like LIKE.TG , which can mask all these complexities and deliver a seamless data integration experience from Shopify to MySQL.

Are you trying to derive deeper insights from PostgreSQL by moving the data into a Data Warehouse like Google BigQuery? Well, you have landed on the right article. Now, it has become easier to replicate data from PostgreSQL to BigQuery.This article will give you a brief overview of PostgreSQL and Google BigQuery. You will also get to know how you can set up your PostgreSQL to BigQuery integration using 2 methods. Moreover, the limitations in the case of the manual method will also be discussed in further sections. Read along to decide which method of connecting PostgreSQL to BigQuery is best for you. Introduction to PostgreSQL PostgreSQL, although primarily used as an OLTP Database, is one of the popular tools for analyzing data at scale. Its novel architecture, reliability at scale, robust feature set, and extensibility give it an advantage over other databases. Introduction to Google BigQuery Google BigQuery is a serverless, cost-effective, and highly scalable Data Warehousing platform with Machine Learning capabilities built-in. The Business Intelligence Engine is used to carry out its operations. It integrates speedy SQL queries with Google’s infrastructure’s processing capacity to manage business transactions, data from several databases, and access control restrictions for users seeing and querying data. BigQuery is used by several firms, including UPS, Twitter, and Dow Jones. BigQuery is used by UPS to predict the exact volume of packages for its various services. BigQuery is used by Twitter to help with ad updates and the combining of millions of data points per second. The following are the features offered by BigQuery for data privacy and protection of your data. These include: Encryption at rest Integration with Cloud Identity Network isolation Access Management for granular access control Methods to Set up PostgreSQL to BigQuery Integration For the scope of this blog, the main focus will be on Method 1 and detail the steps and challenges. Towards the end, you will also get to know about both methods, so that you have the right details to make a choice. Below are the 2 methods: Method 1: Using LIKE.TG Data to Set Up PostgreSQL to BigQuery Integration The steps to load data from PostgreSQL to BigQuery using LIKE.TG Data are as follows: Step 1: Connect your PostgreSQL account to LIKE.TG ’s platform. LIKE.TG has an in-built PostgreSQL Integration that connects to your account within minutes. Move Data from PostgreSQL to BigQueryGet a DemoTry itMove Data from Salesforce to BigQueryGet a DemoTry itMove Data from Google Ads to BigQueryGet a DemoTry itMove Data from MongoDB to BigQueryGet a DemoTry it The available ingestion modes are Logical Replication, Table, and Custom SQL. Additionally, the XMIN ingestion mode is available for Early Access. Logical Replication is the recommended ingestion mode and is selected by default. Step 2: Select Google BigQuery as your destination and start moving your data. With this, you have successfully set up Postgres to BigQuery replication using LIKE.TG Data. Here are more reasons to try LIKE.TG : Schema Management: LIKE.TG takes away the tedious task of schema management automatically detects the schema of incoming data and maps it to the destination schema. Incremental Data Load: LIKE.TG allows the transfer of data that has been modified in real-time. This ensures efficient utilization of bandwidth on both ends. Data Transformation:It provides a simple interface to perfect, modify, and enrich the data you want to transfer. Method 2: Manual ETL Process to Set Up PostgreSQL to BigQuery Integration To execute the following steps, you need a pre-existing database and a table populated with PostgreSQL records. Let’s take a detailed look at each step. Step 1: Extract Data From PostgreSQL The data from PostgreSQL needs to be extracted and exported into a CSV file. To do that, write the following command in the PostgreSQL workbench. COPY your_table_name TO ‘new_file_location\new_file_name’ CSV HEADER After the data is successfully migrated to a CSV file, you should see the above message on your console. Step 2: Clean and Transform Data To upload the data to Google BigQuery, you need the tables and the data to be compatible with the bigQuery format. The following things need to be kept in mind while migrating data to bigQuery: BigQuery expects CSV data to be UTF-8 encoded. BigQuery doesn’t enforce Primary Key and unique key constraints. Your ETL process must do so. Postgres and BigQuery have different column types. However, most of them are convertible. The following table lists common data types and their equivalent conversion type in BigQuery. You can visit their official page to know more about BigQuery data types. DATE value must be a dash(-) separated and in the form YYYY-MM-DD (year-month-day). Fortunately, the default date format in Postgres is the same, YYYY-MM-DD.So if you are simply selecting date columns it should be the incorrect format. The TO_DATE function in PostgreSQL helps in converting string values into dates. If the data is stored as a string in the table for any reason, it can be converted while selecting data. Syntax : TO_DATE(str,format) Example : SELECT TO_DATE('31,12,1999','%d,%m,%Y'); Result : 1999-12-31 In TIMESTAMP type, the hh:mm:ss (hour-minute-second) portion must use a colon (:) separator. Similar to the Date type, the TO_TIMESTAMP function in PostgreSQL is used to convert strings into timestamps. Syntax : TO_TIMESTAMP(str,format) Example : SELECT TO_TIMESTAMP('2017-03-31 9:30:20','YYYY-MM-DD HH:MI:SS'); Result: 2017-03-31 09:30:20-07 Make sure text columns are quoted if they can potentially have delimiter characters. Step 3: Upload to Google Cloud Storage(GCS) bucket If you haven’t already, you need to create a storage bucket in Google Cloud for the next step 3. a) Go to your Google Cloud account and Select the Cloud Storage → Bucket. 3. b) Select a bucket from your existing list of buckets. If you do not have a previously existing bucket, you must create a new one. You can follow Google’s Official documentation to create a new bucket. 3. c) Upload your .csv file into the bucket by clicking the upload file option. Select the file that you want to upload. Step 4: Upload to BigQuery table from GCS 4. a) Go to the Google Cloud console and select BigQuery from the dropdown. Once you do so, a list of project IDs will appear. Select the Project ID you want to work with and select Create Dataset 4. b) Provide the configuration per your requirements and create the dataset. Your dataset should be successfully created after this process. 4. c) Next, you must create a table in this dataset. To do so, select the project ID where you had created the dataset and then select the dataset name that was just created. Then click on Create Table from the menu, which appears at the side. 4. d) To create a table, select the source as Google Cloud Storage. Next, select the correct GCS bucket with the .csv file. Then, select the file format that matches the GCS bucket. In your case, it should be in .csv file format. You must provide a table name for your table in the bigQuery database. Select the mapping option as automapping if you want to migrate the data as it is. 4. e) Your table should be created next and loaded with the same data from PostgreSQL. Step 5: Query the table in BigQuery After loading the table into bigQuery, you can query it by selecting the QUERY option above the table. You can query your table by writing basic SQL syntax. Note: Mention the correct project ID, dataset name, and table name. The above query extracts records from the emp table where the job is manager. Advantages of manually loading the data from PostgreSQL to BigQuery: Manual migration doesn’t require setting up and maintaining additional infrastructure, which can save on operational costs. Manual migration processes are straightforward and involve fewer components, reducing the complexity of the operation. You have complete control over each step of the migration process, allowing for customized data handling and immediate troubleshooting if issues arise. By manually managing data transfer, you can ensure compliance with specific security and privacy requirements that might be critical for your organization. Does PostgreSQL Work As a Data Warehouse? Yes, you can use PostgreSQL as a data warehouse. But, the main challenges are, A data engineer will have to build a data warehouse architecture on top of the existing design of PostgreSQL. To store and build models, you will need to create multiple interlinked databases. But, as PostgreSQL lacks the capability for advanced analytics and reporting, this will further limit the use of it. PostgreSQL can’t handle the data processing of huge data volume. Data warehouses have the features such as parallel processing for advanced queries which PostgreSQL lacks. This level of scalability and performance with minimal latency is not possible with the database. Limitations of the Manual Method: The manual migration process can be time-consuming, requiring significant effort to export, transform, and load data, especially if the dataset is large or complex. Manual processes are susceptible to human errors, such as incorrect data export settings, file handling mistakes, or misconfigurations during import. If the migration needs to be performed regularly or involves multiple tables and datasets, the repetitive nature of manual processes can lead to inefficiency and increased workload. Manual migrations can be resource-intensive, consuming significant computational and human resources, which could be utilized for other critical tasks. Additional Read – Migrate Data from Postgres to MySQL PostgreSQL to Oracle Migration Connect PostgreSQL to MongoDB Connect PostgreSQL to Redshift Replicate Postgres to Snowflake Conclusion Migrating data from PostgreSQL to BigQuery manually can be complex, but automated data pipeline tools can significantly simplify the process. We’ve discussed two methods for moving data from PostgreSQL to BigQuery: the manual process, which requires a lot of configuration and effort, and automated tools like LIKE.TG Data. Whether you choose a manual approach or leverage data pipeline tools like LIKE.TG Data, following the steps outlined in this guide will help ensure a successful migration. FAQ on PostgreSQL to BigQuery How do you transfer data from Postgres to BigQuery? To transfer data from PostgreSQL to BigQuery, export your PostgreSQL data to a format like CSV or JSON, then use BigQuery’s data import tools or APIs to load the data into BigQuery tables. Can I use PostgreSQL in BigQuery? No, BigQuery does not natively support PostgreSQL as a database engine. It is a separate service with its own architecture and SQL dialect optimized for large-scale analytics and data warehousing. Can PostgreSQL be used for Big Data? Yes, PostgreSQL can handle large datasets and complex queries effectively, making it suitable for big data applications. How do you migrate data from Postgres to Oracle? To migrate data from PostgreSQL to Oracle, use Oracle’s Data Pump utility or SQL Developer to export PostgreSQL data as SQL scripts or CSV files, then import them into Oracle using SQL Loader or SQL Developer.

If you’re looking for DynamoDB Snowflake migration, you’ve come to the right place. Initially, the article provides an overview of the two Database environments while briefly touching on a few of their nuances. Later on, it dives deep into what it takes to implement a solution on your own if you are to attempt the ETL process of setting up and managing a Data Pipeline that moves data from DynamoDB to Snowflake.The article wraps up by pointing out some of the challenges associated with developing a custom ETL solution for loading data from DynamoDB to Snowflake and why it might be worth the investment in having an ETL Cloud service provider, LIKE.TG , implement and manage such a Data Pipeline for you. Solve your data replication problems with LIKE.TG ’s reliable, no-code, automated pipelines with 150+ connectors.Get your free trial right away! Overview of DynamoDB and Snowflake DynamoDB is a fully managed, NoSQL Database that stores data in the form of key-value pairs as well as documents. It is part of Amazon’s Data Warehousing suite of services called Amazon Web Services (AWS). DynamoDB is known for its super-fast data processing capabilities that boast the ability to process more than 20 million requests per second. In terms of backup management for Database tables, it has the option for On-Demand Backups, in addition to Periodic or Continuous Backups. Snowflake is a fully managed, Cloud Data Warehousing solution available to customers in the form of Software-as-a-Service (SaaS) or Database-as-a-Service (DaaS). Snowflake follows the standard ANSI SQL protocol that supports fully Structured as well as Semi-Structured data like JSON, Parquet, XML, etc. It is highly scalable in terms of the number of users and computing power while offering pricing at per-second levels of resource usage. How to move data from DynamoDB to Snowflake There are two popular methods to perform Data Migration from DynamoDB to Snowflake: Method 1: Build Custom ETL Scripts to move from DynamoDB data to SnowflakeMethod 2: Implement an Official Snowflake ETL Partner such as Hevo Data. This post covers the first approach in great detail. The blog also highlights the Challenges of Moving Data from DynamoDB to Snowflake using Custom ETL and discusses the means to overcome them. So, read along to understand the steps to export data from DynamoDB to Snowflake in detail. Moving Data from DynamoDB to Snowflake using Custom ETL In this section, you understand the steps to create a Custom Data Pipeline to load data from DynamoDB to Snowflake. A Data Pipeline that enables the flow of data from DynamoDB to Snowflake can be characterized through the following steps – Step 1: Set Up Amazon S3 to Receive Data from DynamoDBStep 2: Export Data from DynamoDB to Amazon S3Step 3: Copy Data from Amazon S3 to Snowflake Tables Step 1: Set Up Amazon S3 to Receive Data from DynamoDB Amazon S3 is a fully managed Cloud file storage, also part of AWS used to export to and import files from, for a variety of purposes. In this use case, S3 is required to temporarily store the data files coming out of DynamoDB before they are loaded into Snowflake tables. To store a data file on S3, one has to create an S3 bucket first. Buckets are placeholders for all objects that are to be stored on Amazon S3. Using the AWS command-line interface, the following is an example command that can be used to create an S3 bucket: $aws s3api create-bucket --bucket dyn-sfl-bucket --region us-east-1 Name of the bucket – dyn-sfl-bucket It is not necessary to create folders in a bucket before copying files over, however, it is a commonly adopted practice, as one bucket can hold a variety of information and folders help with better organization and reduce clutter. The following command can be used to create folders – aws s3api put-object --bucket dyn-sfl-bucket --key dynsfl/ Folder name – dynsfl Step 2: Export Data from DynamoDB to Amazon S3 Once an S3 bucket has been created with the appropriate permissions, you can now proceed to export data from DynamoDB. First, let’s look at an example of exporting a single DynamoDB table onto S3. It is a fairly quick process, as follows: First, you export the table data into a CSV file as shown below. aws dynamodb scan --table-name YOURTABLE --output text > outputfile.txt The above command would produce a tab-separated output file which can then be easily converted to a CSV file. Later, this CSV file (testLIKE.TG .csv, let’s say) could then be uploaded to the previously created S3 bucket using the following command: $aws s3 cp testLIKE.TG .csv s3://dyn-sfl-bucket/dynsfl/ In reality, however, one would need to export tens of tables, sequentially or parallelly, in a repetitive fashion at fixed intervals (ex: once in a 24 hour period). For this, Amazon provides an option to create Data Pipelines. Here is an outline of the steps involved in facilitating data movement from DynamoDB to S3 using a Data Pipeline: Create and validate the Pipeline. The following command can be used to create a Data Pipeline: $aws datapipeline create-pipeline --name dyn-sfl-pipeline --unique-id token { "pipelineId": "ex-pipeline111" } The next step is to upload and validate the Pipeline using a pre-created Pipeline file in JSON format $aws datapipeline put-pipeline-definition --pipeline-id ex-pipeline111 --pipeline-definition file://dyn-sfl-pipe-definition.json Activate the Pipeline. Once the above step is completed with no validation errors, this pipeline can be activated using the following – $aws datapipeline activate-pipeline --pipeline-id ex-pipeline111 Monitor the Pipeline run and verify the data export. The following command shows the execution status: $aws datapipeline list-runs --pipeline-id ex-pipeline111 Once the ‘Status Ended’ section indicates completion of the execution, go over to the S3 bucket s3://dyn-sfl-bucket/dynsfl/ and check to see if the required export files are available. Defining the Pipeline file dyn-sfl-pipe-definition.json can be quite time consuming as there are many things to be defined. Here is a sample file indicating some of the objects and parameters that are to be defined: { "objects": [ { "myComment": "Write a comment here to describe what this section is for and how things are defined", "id": "dyn-to-sfl", "failureAndRerunMode":"cascade", "resourceRole": "DataPipelineDefaultResourceRole", "role": "DataPipelineDefaultRole", "pipelineLogUri": "s3://", "schedule": { "ref": "DefaultSchedule" } "scheduleType": "cron", "name": "Default" "id": "Default" }, { "type": "Schedule", "id": "dyn-to-sfl", "startDateTime" : "2019-06-10T03:00:01" "occurrences": "1", "period": "24 hours", "maxActiveInstances" : "1" } ], "parameters": [ { "description": "S3 Output Location", "id": "DynSflS3Loc", "type": "AWS::S3::ObjectKey" }, { "description": "Table Name", "id": "LIKE.TG _dynamo", "type": "String" } ] } As you can see in the above file definition, it is possible to set the scheduling parameters for the Pipeline execution. In this case, the start date and time are set to June 1st, 2019 early morning and the execution frequency is set to once a day. Step 3: Copy Data from Amazon S3 to Snowflake Tables Once the DynamoDB export files are available on S3, they can be copied over to the appropriate Snowflake tables using a ‘COPY INTO’ command that looks similar to a copy command used in a command prompt. It has a ‘source’, a ‘destination’ and a set of parameters to further define the specific copy operation. A couple of ways to use the COPY command are as follows: File format: copy into LIKE.TG _sfl from s3://dyn-sfl-bucket/dynsfl/testLIKE.TG .csv credentials=(aws_key_id='ABC123' aws_secret_key='XYZabc) file_format = (type = csv field_delimiter = ','); Pattern Matching: copy into LIKE.TG _sfl from s3://dyn-sfl-bucket/dynsfl/ credentials=(aws_key_id='ABC123' aws_secret_key=''XYZabc) pattern='*LIKE.TG *.csv'; Just like before, the above is an example of how to use individual COPY commands for quick Ad Hoc Data Migration, however, in reality, this process will be automated and has to be scalable. In that regard, Snowflake provides an option to automatically detect and ingest staged files when they become available in the S3 buckets. This feature is called Automatic Data Loading using Snowpipe.Here are the main features of a Snowpipe: Snowpipe can be set up in a few different ways to look for newly staged files and load them based on a pre-defined COPY command. An example here is to create a Simple-Queue-Service notification that can trigger the Snowpipe data load.In the case of multiple files, Snowpipe appends these files into a loading queue. Generally, the older files are loaded first, however, this is not guaranteed to happen.Snowpipe keeps a log of all the S3 files that have already been loaded – this helps it identify a duplicate data load and ignore such a load when it is attempted. Hurray!! You have successfully loaded data from DynamoDB to Snowflake using Custom ETL Data Pipeline. Challenges of Moving Data from DynamoDB to Snowflake using Custom ETL Now that you have an idea of what goes into developing a Custom ETL Pipeline to move DynamoDB data to Snowflake, it should be quite apparent that this is not a trivial task. To further expand on that, here are a few things that highlight the intricacies and complexities of building and maintaining such a Data Pipeline: DynamoDB export is a heavily involved process, not least because of having to work with JSON files. Also, when it comes to regular operations and maintenance, the Data Pipeline should be robust enough to handle different types of data errors.Additional mechanisms need to be put in place to handle incremental data changes from DynamoDB to S3, as running full loads every time is very inefficient.Most of this process should be automated so that real-time data is available as soon as possible for analysis. Setting everything up with high confidence in the consistency and reliability of such a Data Pipeline can be a huge undertaking.Once everything is set up, the next thing a growing data infrastructure is going to face is scaling. Depending on the growth, things can scale up really quickly and if the existing mechanisms are not built to handle this scale, it can become a problem.

Are you tired of locally storing and managing files on your Postgres server? You can move your precious data to a powerful destination such as Amazon Redshift, and that too within minutes.Data engineers are given the task of moving data between storage systems like applications, databases, data warehouses, and data lakes. This can be exhaustive and cumbersome. You can follow this simple step-by-step approach to transfer your data from PostgreSQL to Redshift so that you don’t have any problems with your data migration journey. Why Replicate Data from Postgres to Redshift? Analytics: Postgres is a powerful and flexible database, but it’s probably not the best choice for analyzing large volumes of data quickly. Redshift is a columnar database that supports massive analytics workloads. Scalability: Redshift can quickly scale without any performance problems, whereas Postgres may not efficiently handle massive datasets. OLTP and OLAP: Redshift is designed for Online Analytical Processing (OLAP), making it ideal for complex queries and data analysis. Whereas, Postgres is an Online Transactional Processing (OLTP) database optimized for transactional data and real-time operations.

Billing enabled AWS account. Step 1: Configure PostgreSQL to export data as CSV Step 1. a) Go to the directory where PostgreSQL is installed. Step 1. b) Open Command Prompt from that file location. Step 1. c) Now, we need to enter into PostgreSQL. To do so, use the command: psql -U postgres Step 1. d) To see the list of databases, you can use the command: \l I have already created a database named productsdb here. We will be exporting tables from this database. This is the table I will be exporting. Step 1. e) To export as .csv, use the following command: \copy products TO '<your_file_location><your_file_name>.csv' DELIMITER ',' CSV HEADER; Note: This will create a new file at the mentioned location. Go to your file location to see the saved CSV file. Step 2: Load CSV to S3 Bucket Step 2. a) Log Into your AWS Console and select S3. Step 2. b) Now, we need to create a new bucket and upload our local CSV file to it. You can click Create Bucket to create a new bucket. Step 2. c) Fill in the bucket name and required details. Note: Uncheck Block Public Access Step 2. d) To upload your CSV file, go to the bucket you created. Click on upload to upload the file to this bucket. You can now see the file you uploaded inside your bucket. Step 3: Move Data from S3 to Redshift Step 3. a) Go to your AWS Console and select Amazon Redshift. Step 3. b) For Redshift to load data from S3, it needs permission to read data from S3. To assign this permission to Redshift, we can create an IAM role for that and go to security and encryption. Click on Manage IAM roles followed by Create IAM role. Note: I will select all s3 buckets. You can select specific buckets and give access to them. Click Create. Step 3. c) Go back to your Namespace and click on Query Data. Step 3. d) Click on Load Data to load data in your Namespace. Click on Browse S3 and select the required Bucket. Note: I don’t have a table created, so I will click Create a new table, and Redshift will automatically create a new table. Note: Select the IAM role you just created and click on Create. Step 3. e) Click on Load Data. A Query will start that will load your data from S3 to Redshift. Step 3. f) Run a Select Query to view your table. Method 2: Using LIKE.TG Data to connect PostgreSQL to Redshift Prerequisites: Access to PostgreSQL credentials. Billing Enabled Amazon Redshift account. Signed Up LIKE.TG Data account. Step 1: Create a new Pipeline Step 2: Configure the Source details Step 2. a) Select the objects that you want to replicate. Step 3: Configure the Destination details. Step 3. a) Give your destination table a prefix name. Note: Keep Schema mapping turned on. This feature by LIKE.TG will automatically map your source table schema to your destination table. Step 4: Your Pipeline is created, and your data will be replicated from PostgreSQL to Amazon Redshift. Limitations of Using Custom ETL Scripts These challenges have an impact on ensuring that you have consistent and accurate data available in your Redshift in near Real-Time. The Custom ETL Script method works well only if you have to move data only once or in batches from PostgreSQL to Redshift. The Custom ETL Script method also fails when you have to move data in near real-time from PostgreSQL to Redshift. A more optimal way is to move incremental data between two syncs from Postgres to Redshift instead of full load. This method is called the Change Data Capture method. When you write custom SQL scripts to extract a subset of data often those scripts break as the source schema keeps changing or evolving. Additional Resources for PostgreSQL Integrations and Migrations How to load data from postgresql to biquery Postgresql on Google Cloud Sql to Bigquery Migrate Data from Postgres to MySQL How to migrate Data from PostgreSQL to SQL Server Export a PostgreSQL Table to a CSV File Conclusion This article detailed two methods for migrating data from PostgreSQL to Redshift, providing comprehensive steps for each approach.

Are you trying to derive deeper insights from your Elasticsearch by moving the data into a larger Database like Amazon S3? Well, you have landed on the right article. This article will give you a brief overview of Elasticsearch and Amazon S3. You will also get to know how you can set up your Elasticsearch to S3 integration using 4 easy steps. Moreover, the limitations of the method will also be discussed in further sections. Read along to know more about connecting Elasticsearch to S3 in the further sections. Note: Currently, LIKE.TG Data doesn’t support S3 as a destination. What is Elasticsearch? Elasticsearch accomplishes its super-fast search capabilities through the use of a Lucene-based distributed reverse index. When a document is loaded to Elasticsearch, it creates a reverse index of all the fields in that document. A reverse index is an index where each of the entries is mapped to a list of documents that contains them. Data is stored in JSON form and can be queried using the proprietary query language. Elasticsearch has four main APIs – Index API, Get API, Search API, and Put Mapping API: Index API is used to add documents to the index. Get API allows to retrieve the documents and Search API enables querying over the index data. Put Mapping API is used to add additional fields to an already existing index. The common practice is to use Elasticsearch as part of the standard ELK stack, which involves three components – Elasticsearch, Logstash, and Kibana: Logstash provides data loading and transformation capabilities. Kibana provides visualization capabilities. Together, three of these components form a powerful Data Stack. Behind the scenes, Elasticsearch uses a cluster of servers to deliver high query performance. An index in Elasticsearch is a collection of documents. Each index is divided into shards that are distributed across different servers. By default, it creates 5 shards per index with each shard having a replica for boosting search performance. Index requests are handled only by the primary shards and search requests are handled by both the shards. The number of shards is a parameter that is constant at the index level. Users with deep knowledge of their data can override the default shard number and allocate more shards per index. A point to note is that a low amount of data distributed across a large number of shards will degrade the performance. Amazon offers a completely managed Elasticsearch service that is priced according to the number of instance hours of operational nodes. To know more about Elasticsearch, visit this link.

AWS S3 is a fully managed object storage service that is used for a variety of use cases like hosting data, backup and archiving, data warehousing, etc. Amazon handles all operational activities related to capacity scaling, pre-provisioning, etc and the customers only need to pay for the amount of space that they use. Here are a couple of key Amazon S3 features: Access Control: It offers comprehensive access controls to meet any kind of organizational and business compliance requirements through an easy-to-use control panel interface. Support for Analytics: S3 supports analytics through the use of AWS Athena and AWS redshift spectrum through which users can execute SQL queries over data stored in S3. Encryption: S3 buckets can be encrypted by S3 default encryption. Once enabled, all items in a particular bucket will be encrypted. High Availability: S3 achieves high availability by storing the data across several distributed servers. Naturally, there is an associated propagation delay with this approach and S3 only guarantees eventual consistency. But, the writes are atomic; which means at any time, the API will return either the new data or old data. It’ll never provide a corrupted response. Conceptually S3 is organized as buckets and objects. A bucket is the highest-level S3 namespace and acts as a container for storing objects. They have a critical role in access control and usage reporting is always aggregated at the bucket level. An object is the fundamental storage entity and consists of the actual object as well as the metadata. An object is uniquely identified by a unique key and a version identifier. Customers can choose the AWS regions in which their buckets need to be located according to their cost and latency requirements. A point to note here is that objects do not support locking and if two PUTs come at the same time, the request with the latest timestamp will win. This means if there is concurrent access, users will have to implement some kind of locking mechanism on their own. To know more about Amazon S3, visit this link. Steps to Connect Elasticsearch to S3 Using Custom Code Moving data from Elasticsearch to S3 can be done in multiple ways. The most straightforward is to write a script to query all the data from an index and write it into a CSV or JSON file. But the limitations to the amount of data that can be queried at once make that approach a nonstarter. You will end up with errors ranging from time outs to too large a window of query. So, you need to consider other approaches to connect Elasticsearch to S3. Logstash, a core part of the ELK stack, is a full-fledged data load and transformation utility. With some adjustment of configuration parameters, it can be made to export all the data in an elastic index to CSV or JSON. The latest release of log stash also includes an S3 plugin, which means the data can be exported to S3 directly without intermediate storage. Thus, Logstash can be used to connect Elasticsearch to S3. Let us look in detail into this approach and its limitations. Using Logstash Logstash is a service-side pipeline that can ingest data from several sources, process or transform them and deliver them to several destinations. In this use case, the Logstash input will be Elasticsearch, and the output will be a CSV file. Thus, you can use Logstash to back up data from Elasticsearch to S3 easily. Logstash is based on data access and delivery plugins and is an ideal tool for connecting Elasticsearch to S3. For this exercise, you need to install the Logstash Elasticsearch plugin and the Logstash S3 plugin. Below is a step-by-step procedure to connect Elasticsearch to S3: Step 1: Execute the below command to install the Logstash Elasticsearch plugin. logstash-plugin install logstash-input-elasticsearch Step 2: Execute the below command to install the logstash output s3 plugin. logstash-plugin install logstash-output-s3 Step 3: Next step involves the creation of a configuration for the Logstash execution. An example configuration to execute this is provided below. input { elasticsearch { hosts => "elastic_search_host" index => "source_index_name" query => ' { "query": { "match_all": {} } } ' } } output { s3{ access_key_id => "aws_access_key" secret_access_key => "aws_secret_key" bucket => "bucket_name" } } In the above JSON, replace the elastic_search_host with the URL of your source Elasticsearch instance. The index key should have the index name as the value. The query tries to match every document present in the index. Remember to also replace the AWS access details and the bucket name with your required details. Create this configuration and name it “es_to_s3.conf”. Step 4: Execute the configuration using the following command. logstash -f es_to_s3.conf The above command will generate JSON output matching the query in the provided S3 location. Depending on your data volume, this will take a few minutes. Multiple parameters that can be adjusted in the S3 configuration to control variables like output file size etc. A detailed description of all config parameters can be found in Elastic Logstash Reference [8.1]. By following the above-mentioned steps, you can easily connect Elasticsearch to S3.

Limitations of Connecting Elasticsearch to S3 Using Custom Code The above approach is the simplest way to transfer data from an Elasticsearch to S3 without using any external tools. But it does have some limitations. Below are two limitations that are associated while setting up Elasticsearch to S3 integrations: This approach to connecting Elasticsearch to S3 works fine for a one-time load, but in most situations, the transfer is a continuous process that needs to be executed based on an interval or triggers. To accommodate such requirements, customized code will be required. This approach to connecting Elasticsearch to S3 is resource-intensive and can hog the cluster depending on the number of indexes and the volume of data that needs to be copied. Conclusion This article provided you with a comprehensive guide to Elasticsearch and Amazon S3. You got to know about the methodology to backup Elasticsearch to S3 using Logstash and its limitations as well. Now, you are in the position to connect Elasticsearch to S3 on your own. The manual approach of connecting Elasticsearch to S3 using Logstash will add complex overheads in terms of time and resources.

Relational databases, such as MySQL, have traditionally helped enterprises manage and analyze massive volumes of data effectively. However, as scalability, real-time analytics, and seamless data integration become increasingly important, contemporary data systems like Snowflake have become strong substitutes. After experimenting with a few different approaches and learning from my failures, I’m excited to share my tried-and-true techniques for moving data from MySQL to Snowflake.In this blog, I’ll walk you through two simple migration techniques: manual and automated. I will also share the factors to consider while choosing the right approach. Select the approach that best meets your needs, and let’s get going! What is MySQL? MySQL is an open-source relational database management system (RDBMS) that allows users to access and manipulate databases using Structured Query Language (SQL). Created in the middle of the 1990s, MySQL’s stability, dependability, and user-friendliness have made it one of the most widely used databases worldwide. Its structured storage feature makes it ideal for organizations that require high-level data integrity, consistency, and reliability. Some significant organizations that use MySQL include Amazon, Uber, Airbnb, and Shopify. Key Features of MySQL : Free to Use: MySQL is open-source, so that you can download, install, and use it without any licensing costs. This allows you to use all the functionalities a robust database management system provides without many barriers. However, for large organizations, it also offers commercial versions like MySQL Cluster Carrier Grade Edition and MySQL Enterprise Edition. Scalability: Suitable for both small and large-scale applications. What is Snowflake? Snowflake is a cloud-based data warehousing platform designed for high performance and scalability. Unlike traditional databases, Snowflake is built on a cloud-native architecture, providing robust data storage, processing, and analytics capabilities. Key Features of Snowflake : Cloud-Native Architecture: Fully managed service that runs on cloud platforms like AWS, Azure, and Google Cloud. Scalability and Elasticity: Automatically scales compute resources to handle varying workloads without manual intervention. Why move MySQL data to Snowflake? Performance and Scalability: MySQL may experience issues managing massive amounts of data and numerous user queries simultaneously as data quantity increases. Snowflake’s cloud-native architecture, which offers nearly limitless scalability and great performance, allows you to handle large datasets and intricate queries effectively. Higher Level Analytics: Snowflake offers advanced analytical features like data science and machine learning workflow assistance. These features can give you deeper insights and promote data-driven decision-making. Economy of Cost: Because Snowflake separates computation and storage resources, you can optimize your expenses by only paying for what you utilize. The pay-as-you-go approach is more economical than the upkeep and expansion of MySQL servers situated on-site. Data Integration and Sharing: Snowflake’s powerful data-sharing features make integrating and securely exchanging data easier across departments and external partners. This skill is valuable for firms seeking to establish a cohesive data environment. Streamlined Upkeep: Snowflake removes the need for database administration duties, which include software patching, hardware provisioning, and backups. It is a fully managed service that enables you to concentrate less on maintenance and more on data analysis. Sync your Data from MySQL to SnowflakeGet a DemoTry itSync your Data from Salesforce to SnowflakeGet a DemoTry itSync your Data from MongoDB to SnowflakeGet a DemoTry it Methods to transfer data from MySQL to Snowflake: Method 1: How to Connect MySQL to Snowflake using Custom Code Prerequisites You should have a Snowflake Account. If you don’t have one, check out Snowflake and register for a trial account. A MySQL server with your database. You can download it from MySQL’s official website if you don’t have one. Let’s examine the step-by-step method for connecting MySQL to Snowflake using the MySQL Application Interface and Snowflake Web Interface. Step 1: Extract Data from MySQL I created a dummy table called cricketers in MySQL for this demo. You can click on the rightmost table icon to view your table. Next, we need to save a .csv file of this table in our local storage to later load it into Snowflake. You can do this by clicking on the icon next to Export/Import. This will automatically save a .csv file of the table that is selected on your local storage. Step 2: Create a new Database in Snowflake Now, we need to import this table into Snowflake. Log into your Snowflake account, click Data>Databases, and click the +Database icon on the right-side panel to create a new database. For this guide, I have already made a database called DEMO. Step 3: Create a new Table in that database Now click DEMO>PUBLIC>Tables, click the Create button, and select the From File option from the drop-down menu. A Dropbox will appear where you can drag and drop your .csv file. Select and create a new table and give it a name. You can also choose from existing tables, and your data will be appended to that table. Step 4: Edit your table schema Click next. In this dialogue box, you can edit the schema. After modifying the schema according to your needs, click the load button. This will start loading your table data from the .csv file to Snowflake. Step 5: Preview your loaded table Once the loading process has been completed, you can view your data by clicking the preview button. Note: An alternative method of moving data is to create an Internal/External stage in Snowflake and load data into it. Limitations of Manually Migrating Data from MySQL to Snowflake: Error-prone: Custom coding and SQL Queries introduce a higher risk of errors potentially leading to data loss or corruption. Time-Consuming: Handling tables for large datasets is highly time-consuming. Orchestration Challenges: Manually migrating data needs more monitoring, alerting, and progress-tracking features. Method 2: How to Connect MySQL to Snowflake using an Automated ETL Platform Prerequisites: To set up your pipeline, you need a LIKE.TG account. If you don’t have one, you can visit LIKE.TG . A Snowflake account. A MySQL server with your database. Step 1:Connect your MySQL account to LIKE.TG ’s Platform. To begin with, I am logging in to my LIKE.TG platform. Next, create a new pipeline by clicking the Pipelines and the +Create button. LIKE.TG provides built-in MySQL integration that can connect to your account within minutes. Choose MySQL as the source and fill in the necessary details. Enter your Source details and click on TEST CONTINUE. Next, Select all the objects that you want to replicate. Objects are nothing but the tables. Step 2: Connect your Snowflake account to LIKE.TG ’s Platform You have successfully connected your source and destination with these two simple steps. From here, LIKE.TG will take over and move your valuable data from MySQL to Snowflake. Advantages of using LIKE.TG : Auto Schema Mapping: LIKE.TG eliminates the tedious task of schema management. It automatically detects the schema of incoming data and maps it to the destination schema. Incremental Data Load: Allows the transfer of modified data in real-time, ensuring efficient bandwidth utilization on both ends. Data Transformation: It provides a simple interface for perfecting, modifying, and enriching the data you want to transfer. Note: Alternatively, you can use SaaS ETL platforms like Estuary or Airbyte to migrate your data. Best Practices for Data Migration: Examine Data and Workloads: Before migrating, constantly evaluate the schema, volume of your data, and kinds of queries currently running in your MySQL databases. Select the Appropriate Migration Technique: Handled ETL Procedure: This procedure is appropriate for smaller datasets or situations requiring precise process control. It requires manually loading data into Snowflake after exporting it from MySQL (for example, using CSV files). Using Snowflake’s Staging: For larger datasets, consider utilizing either the internal or external stages of Snowflake. Using a staging area, you can import the data into Snowflake after exporting it from MySQL to a CSV or SQL dump file. Validation of Data and Quality Assurance: Assure data integrity before and after migration by verifying data types, restrictions, and completeness. Verify the correctness and consistency of the data after migration by running checks. Enhance Information for Snowflake: Take advantage of Snowflake’s performance optimizations. Utilize clustering keys to arrange information. Make use of Snowflake’s built-in automatic query optimization tools. Think about using query pattern-based partitioning methods. Manage Schema Changes and Data Transformations: Adjust the MySQL schema to meet Snowflake’s needs. Snowflake supports semi-structured data, although the structure of the data may need to be changed. Plan the necessary changes and carry them out during the migration process. Verify that the syntax and functionality of SQL queries are compatible with Snowflake. Troubleshooting Common Issues : Problems with Connectivity: Verify that Snowflake and MySQL have the appropriate permissions and network setup. Diagnose connectivity issues as soon as possible by utilizing monitoring and logging technologies. Performance bottlenecks: Track query performance both before and after the move. Optimize SQL queries for the query optimizer and architecture of Snowflake. Mismatches in Data Type and Format: Identify and resolve format and data type differences between Snowflake and MySQL. When migrating data, make use of the proper data conversion techniques. Conclusion: You can now seamlessly connect MySQL to Snowflake using manual or automated methods.

There are many use cases when you must migrate MySQL database between 2 servers, like cloning a database for testing, a separate database for running reports, or completely migrating a database system to a new server. Broadly, you will take a data backup on the first server, transfer it remotely to the destination server, and finally restore the backup on the new MySQL instance. This article will walk you through the steps to migrate MySQL Database between 2 Servers using 3 simple steps. Additionally, we will explore the process of performing a MySQL migration, using copy MySQL database from one server to another operation. This process is crucial when you want to move your MySQL database to another server without losing any data or functionality. We will cover the necessary steps and considerations involved in successfully completing a MySQL migration. So, whether you are looking to clone a database, create a separate database for reporting purposes, or completely migrate your database to a new server, this guide will provide you with the information you need. Steps to Migrate MySQL Database Between 2 Servers Let’s understand the steps to migrate the MySQL database between 2 servers. Understanding the process of transferring MySQL databases from one server to another is crucial for maintaining data integrity and continuity of services. To migrate MySQL database seamlessly, ensure both source and target servers are compatible. Below are the steps you can follow to understand how to migrate MySQL database between 2 servers: Step 1: Backup the Data Step 2:Copy the Database Dump on the Destination Server Step 3: Restore the Dump‘ Want to migrate your SQL data effortlessly? Check out LIKE.TG ’s no-code data pipeline that allows you to migrate data from any source to a destination with just a few clicks. Start your 14 days trial now for free! Get Started with LIKE.TG for Free 1) Backup the Data The first step to migrate MySQL database is to take a dump of the data that you want to transfer. This operation will help you move mysql database to another server. To do that, you will have to use mysqldump command. The basic syntax of the command is: mysqldump -u [username] -p [database] > dump.sql If the database is on a remote server, either log in to that system using ssh or use -h and -P options to provide host and port respectively. mysqldump -P [port] -h [host] -u [username] -p [database] > dump.sql There are various options available for this command, let’s go through the major ones as per the use case. A) Backing Up Specific Databases mysqldump -u [username] -p [database] > dump.sql This command dumps specified databases to the file. You can specify multiple databases for the dump using the following command: mysqldump -u [username] -p --databases [database1] [database2] > dump.sql You can use the –all-databases option to backup all databases on the MySQL instance. mysqldump -u [username] -p --all-databases > dump.sql B) Backing Up Specific Tables The above commands dump all the tables in the specified database, if you need to take backup of some specific tables, you can use the following command: mysqldump -u [username] -p [database] [table1] [table2] > dump.sql C) Custom Query If you want to backup data using some custom query, you will need to use the where option provided by mysqldump. mysqldump -u [username] -p [database] [table1] --where="WHERE CLAUSE" > dump.sql Example: mysqldump -u root -p testdb table1 --where="mycolumn = myvalue" > dump.sql Note: By default, mysqldump command includes DROP TABLE and CREATE TABLE statements in the created dump. Hence, if you are using incremental backups or you specifically want to restore data without deleting previous data, make sure you use the –no-create-info option while creating a dump. mysqldump -u [username] -p [database] --no-create-info > dump.sql If you need just to copy the schema but not the data, you can use –no-data option while creating the dump. mysqldump -u [username] -p [database] --no-data > dump.sql Other use cases Here’s a list of uses for the mysqldump command based on use cases: To backup a single database: mysqldump -u [username] -p [database] > dump.sql To backup multiple databases: mysqldump -u [username] -p --databases [database1] [database2] > dump.sql To backup all databases on the instance: mysqldump -u [username] -p --all-databases > dump.sql To backup specific tables: mysqldump -u [username] -p [database] [table1] [table2] > dump.sql To backup data using some custom query: mysqldump -u [username] -p [database] [table1] --where="WHERE CLAUSE" > dump.sql Example: mysqldump -u root -p testdb table1 --where="mycolumn = myvalue" > dump.sql To copy only the schema but not the data: mysqldump -u [username] -p [database] --no-data > dump.sq To restore data without deleting previous data (incremental backups): mysqldump -u [username] -p [database] --no-create-info > dump.sql 2) Copy the Database Dump on the Destination Server Once you have created the dump as per your specification, the next step to migrate MySQL database is to use the data dump file to move the MySQL database to another server (destination). You will have to use the “scp” command for that. Scp -P [port] [dump_file].sql [username]@[servername]:[path on destination] Examples: scp dump.sql [email protected]:/var/data/mysql scp -P 3306 dump.sql [email protected]:/var/data/mysql To copy to a single database, use this syntax: scp all_databases.sql [email protected]:~/ For a single database: scp database_name.sql [email protected]:~/ Here’s an example: scp dump.sql [email protected]:/var/data/mysql scp -P 3306 dump.sql [email protected] 3) Restore the Dump The last step in MySQL migration is restoring the data on the destination server. MySQL command directly provides a way to restore to dump data to MySQL. mysql -u [username] -p [database] < [dump_file].sql Example: mysql -u root -p testdb < dump.sql Don’t specify the database in the above command if your dump includes multiple databases. mysql -u root -p < dump.sql For all databases: mysql -u [user] -p --all-databases < all_databases.sql For a single database: mysql -u [user] -p newdatabase < database_name.sql For multiple databases: mysql -u root -p < dump.sql Limitations with Dumping and Importing MySQL Data Dumping and importing MySQL data can present several challenges: Time Consumption: The process can be time-consuming, particularly for large databases, due to creating, transferring, and importing dump files, which may slow down with network speed and database size. Potential for Errors: Human error is a significant risk, including overlooking steps, misconfiguring settings, or using incorrect parameters with the mysqldump command. Data Integrity Issues: Activities on the source database during the dump process can lead to data inconsistencies in the exported SQL dump. Measures like putting the database in read-only mode or locking tables can mitigate this but may impact application availability. Memory Limitations: Importing massive SQL dump files may encounter memory constraints, necessitating adjustments to MySQL server configurations on the destination machine.

Method 2: Writing Custom Scripts to Move Data from Facebook Ads to BigQuery Migrating data from Facebook Ads Insights to Google BigQuery essentially involves two key steps: Step 1: Pulling Data from Facebook Step 2: Loading Data into BigQuery Step 1: Pulling Data from Facebook Put simply, pulling data from Facebook involves downloading the relevant Ads Insights data, which can be used for a variety of business purposes. Currently, there are two main methods for users to pull data from Facebook: Through APIs. Through Real-time streams. Method 1: Through APIs Users can access Facebook’s APIs through the different SDKs offered by the platform. While Python and PHP are the main languages supported by Facebook, it’s easy to find community-supported SDKs for languages such as JavaScript, R, and Ruby. What’s more, the Facebook Marketing API is relatively easy to use – which is why it can be harnessed to execute requests that direct to specific endpoints. Also, since the Facebook Marketing API is a RESTful API, you can interact with it via your favorite framework or language. Like everything else Facebook-related, Ads and statistics data form part of and can be acquired through the Graph API, and any requests for statistics specific to particular ads can be sent to Facebook Insights. In turn, Insights will reply to such requests with more information on the queried ad object. If the above seems overwhelming, there’s no need to worry and we’ll be taking a look at an example to help simplify things. Suppose you want to extract all stats relevant to your account. This can be done by executing the following simple request through curl: curl -F 'level=campaign' -F 'fields=[]' -F 'access_token=<ACCESS_TOKEN>' https://graph.facebook.com/v2.5/<CAMPAIGN_ID>/insights curl -G -d 'access_token=<ACCESS_TOKEN>' https://graph.facebook.com/v2.5/1000002 curl -G -d 'access_token=<ACCESS_TOKEN>' https://graph.facebook.com/v2.5/1000002/insights Once it’s ready, the data you’ve requested will then be returned in either CSV or XLS format and be able to access it via a URL such as the one below: https://www.facebook.com/ads/ads_insights/export_report?report_run_id=<REPORT_ID> format=<REPORT_FORMAT>access_token=<ACCESS_TOKEN Method 2: Through Real-time Streams You can also pull data from Facebook by creating a real-time data substructure and can even load your data into the data warehouse. All you need to do to achieve all this and to receive API updates is to subscribe to real-time updates. Using the right substructure, you’ll be able to stream an almost real-time data feed to your database, and by doing so, you’ll be kept up-to-date with the latest data. Facebook Ads boasts a tremendously rich API that offers users the opportunity to extract even the smallest portions of data regarding accounts and target audience activities. More importantly, however, is that all of this real-time data can be used for analytics and reporting purposes. However, there’s a minor consideration that needs to be mentioned. It’s no secret that these resources become more complex as they continue to grow, meaning you’ll need a complex protocol to handle them and it’s worth keeping this in mind as the volume of your data grows with each passing day. Moving on, the data that you pull from Facebook can be in one of a plethora of different formats, yet BigQuery isn’t compatible with all of them. This means that it’s in your best interest to convert data into a format supported by BigQuery after you’ve pulled it from Facebook. For example, if you pull XML data, then you’ll need to convert it into any of the following data formats: CSV JSON. You should also make sure that BigQuery supports the BigQuery data types you’re using. BigQuery currently supports the following data types: STRING INTEGER FLOAT BOOLEAN RECORD TIMESTAMP Please refer to Google’s documentation on preparing data for BigQuery, to learn more. Now that you’ve understood the different data formats and types supported by BigQuery, it’s time to learn how to pull data from Facebook. Step 2: Loading Data Into BigQuery If you opt to use Google Cloud Storage to load data from Facebook Ads into BigQuery, then you’ll need to first load the data into Google Cloud Storage. This can be done in one of a few ways. First and foremost, this can be done directly through the console. Alternatively, you can post data with the help of the JSON API. One thing to note here is that APIs play a crucial role, both in pulling data from Facebook Ads and loading data into Bigquery. Perhaps the simplest way to load data into BigQuery is by requesting HTTP POST using tools such as curl. Should you decide to go this route, your POST request should look something like this: POST /upload/storage/v1/b/myBucket/o?uploadType=medianame= TEST HTTP/1.1 Host: www.googleapis.com Content-Type: application/text Content-Length: number_of_bytes_in_file Authorization: Bearer your_auth_token your Facebook Ads data And if you enter everything correctly you’ll get a response that looks like this: HTTP/1.1 200 Content-Type: application/json { "name": "TEST" } However, remember that tools like curl are only useful for testing purposes. So, you’ll need to write specific codes to send data to Google if you want to automate the data loading process. This can be done in one of the following languages when using the Google App Engine to write codes: Python Java PHP Go Apart from coding for the Google App Engine, the above languages can even be used to access Google Cloud Storage. Once you’ve imported your extracted data into Google Cloud Storage, you’ll need to create and run a LoadJob, which directs to the data that needs to be imported from the cloud and will ultimately load the data into BigQuery. This works by specifying source URLs that point to the queried objects. This method makes use of POST requests for storing data in the Google Cloud Storage API, from where it will load the data into BigQuery. Another method to accomplish this is by posting a direct HTTP POST request to BigQuery with the data you’d like to query. While this method is very similar to loading data through the JSON API, it differs by using specific BigQuery end-points to load data directly. Furthermore, the interaction is quite simple and can be carried out via either the framework or the HTTP client library of your preferred language. Limitations of using Custom Scripts to Connect Facebook Ads to BigQuery Building a custom code for transfer data from Facebook Ads to Google BigQuery may appear to be a practically sound arrangement. However, this approach comes with some limitations too. Code Maintenance: Since you are building the code yourself, you would need to monitor and maintain it too. On the off chance that Facebook refreshes its API or the API sends a field with a datatype which your code doesn’t understand, you would need to have resources that can handle these ad-hoc requests. Data Consistency: You additionally will need to set up a data validation system in place to ensure that there is no data leakage in the infrastructure. Real-time Data: The above approach can help you move data one time from Facebook Ads to BigQuery. If you are looking to analyze data in real-time, you will need to deploy additional code on top of this. Data Transformation Capabilities: Often, there will arise a need for you to transform the data received from Facebook before analyzing it. Eg: When running ads across different geographies globally, you will want to convert the timezones and currencies from your raw data and bring them to a standard format. This would require extra effort. Utilizing a Data Integration stage like LIKE.TG frees you of the above constraints. Method 3: Manual Upload of Data from Facebook Ads to BigQuery This is an affordable solution for moving data from Facebook Ads to BigQuery. These are the steps that you can carry out to load data from Facebook Ads to BigQuery manually: Step 1: Create a Google Cloud project, after which you will be taken to a “Basic Checklist”. Next, navigate to Google BigQuery and look for your new project. Step 2: Log In to Facebook Ads Manager and navigate to the data you wish to query in Google BigQuery. If you need daily data, you need to segment your reports by day. Step 3: Download the data by selecting “Reports” and then click on “Export Table Data”. Export your data as a .csv file and save it on your PC. Step 4: Navigate back to Google BigQuery and ensure that your project is selected at the top of the screen. Click on your project ID in the left-hand navigation and click on “+ Create Dataset” Step 5: Provide a name for your dataset and ensure that an encryption method is set. Click on “Create Dataset” followed by clicking on the name of your new dataset in the left-hand navigation. Next, click on “Create Table” to finish this step. Step 6: Go to the source section, then create your table from the Upload option. Find your Facebook Ads report that you saved to your PC and choose file format as CSV. In the destination section, select “Search for a project”. Next, find your project name from the dropdown list. Select your dataset name and the name of the table. Step 7: Go to the schema section and click on the checkbox to allow BigQuery to either auto-detect a schema or click on “Edit as Text” to manually name schema, set mode, and type. Step 8: Go to the Partition and Cluster Settings section and choose “Partition by Ingestion Time” or “No partitioning” based on your needs. Partitioning splits your table into smaller segments that allow smaller sections of data to be queried quickly. Next, navigate to Advanced options and set the field delimiter like a comma. Step 9: Click “Create table”. Your Data Warehouse will begin to populate with Facebook Ads data. You can check your Job History for the status of your data load. Navigate to Google BigQuery and click on your dataset ID. Step 10: You can write SQL queries against your Facebook data in Google BigQuery, or export your data to Google Data Studio along with other third-party tools for further analysis. You can repeat this process for all additional Facebook data sets you wish to upload and ensure fresh data availability. Limitations of Manual Upload of Data from Facebook Ads to BigQuery Data Extraction: Downloading data from Facebook Ads manually for large-scale data is a daunting and time-consuming task. Data Uploads: A manual process of uploading will need to be watched and involved in continuously. Human Error: In a manual process, errors such as mistakes in data entry, omitted uploads, and duplication of records can take place. Data Integrity: There is no automated assurance mechanism to ensure that integrity and consistency of the data. Delays: Manual uploads run the risk of creating delays in availability and the real integration of data for analysis. Benefits of sending data from Facebook Ads to Google BigQuery Identify patterns with SQL queries: To gain deeper insights into your ad performance, you can use advanced SQL queries. This helps you to analyze data from multiple angles, spot patterns, and understand metric correlations. Conduct multi-channel ad analysis: You can integrate your Facebook Ads data with metrics from other sources like Google Ads, Google Analytics 4, CRM, or email marketing apps. By doing this, you can analyze your overall marketing performance and understand how different channels work together. Analyze ad performance in-depth: You can carry out a time series analysis to identify changes in ad performance over time and understand how factors like seasonality impact ad performance. Leverage ML algorithms: You can also build ML models and train them to forecast future performance, identify which factors drive ad success, and optimize your campaigns accordingly. Data Visualization: ​​Build powerful interactive dashboards by connecting BigQuery to PowerBI, Looker Studio (former Google Data Studio), or another data visualization tool. This enables you to create custom dashboards that showcase your key metrics, highlight trends, and provide actionable insights to drive better marketing decisions. Use Cases of Loading Facebook Ads to BigQuery Marketing Campaigns: Analyzing facebook ads audience data in bigquery can help you to enhance the performance of your marketing campaigns. Advertisement data from Facebook combined with business data in BigQuery can give better insights for decision-making. Personalized Audience Targeting: On Facebook ads conversion data in BigQuery, you can utilize BigQuery’s powerful querying capabilities to segment audiences based on detailed demographics, interests, and behaviors extracted from Facebook Ads data. Competitive Analysis: You can compare your Facebook attribution data in BigQuery to understand the Ads performance of industry competitors using publicly available data sources. Get Real-time Streams of Your Facebook Ad Statistics You can easily create a real-time data infrastructure for extracting data from Facebook Ads and loading them into a Data Warehouse repository. You can achieve this by subscribing to real-time updates to receive API updates with Webhooks. Armed with the proper infrastructure, you can have an almost real-time data feed into your repository and ensure that it will always be up to date with the latest bit of data. Facebook Ads is a real-time bidding system where advertisers can compete to showcase their advertising material. Facebook Ads imparts a very rich API that gives you the opportunity to get extremely granular data regarding your accounting activities and leverage it for reporting and analytic purposes. This richness will cost you, though many complex resources must be tackled with an equally intricate protocol. Prepare Your Facebook Ads Data for Google BigQuery Before diving into the methods that can be deployed to set up a connection from Facebook Ads to BigQuery, you should ensure that it is furnished in an appropriate format. For instance, if the API you pull data from returns an XML file, you would first have to transform it to a serialization that can be understood by BigQuery. As of now, the following two data formats are supported: JSON CSV Apart from this, you also need to ensure that the data types you leverage are the ones supported by Google BigQuery, which are as follows: FLOAT RECORD TIMESTAMP INTEGER FLOAT STRING Additional Resources on Facebook Ads To Bigquery Explore how to Load Data into Bigquery Conclusion This blog talks about the 3 different methods you can use to move data from Facebook Ads to BigQuery in a seamless fashion.

Many businesses today use a variety of cloud-based applications for day-to-day business, like Salesforce, HubSpot, Mailchimp, Zendesk, etc. Companies are also very keen to combine this data with other sources to measure key metrics that help them grow.Given most of the cloud applications are owned and run by third-party vendors – the applications expose their APIs to help companies extract the data into a data warehouse – say, Google BigQuery. This blog details out the process you would need to follow to move data from API to BigQuery. Besides learning about the data migration process from rest API to BigQuery, we’ll also learn about their shortcomings and the workarounds. Let’s get started. Note: When you connect API to BigQuery, consider factors like data format, update frequency, and API rate limits to design a stable integration.

Method 2: API to BigQuery ETL Using Custom Code The BigQuery Data Transfer Service provides a way to schedule and manage transfers from REST API datasource to Bigquery for supported applications. One advantage of the REST API to Google BigQuery is the ability to perform actions (like inserting data or creating tables) that might not be directly supported by the web-based BigQuery interface. The steps involved in migrating data from API to BigQuery are as follows: Getting your data out of your application using API Preparing the data that was extracted from the Application Loading data into Google BigQuery Step 1: Getting data out of your application using API Below are the steps to extract data from the application using API. Get the API URL from where you need to extract the data. In this article, you will learn how to use Python to extract data from ExchangeRatesAPI.io which is a free service for current and historical foreign exchange rates published by the European Central Bank. The same method should broadly work for any API that you would want to use. API URL = https://api.exchangeratesapi.io/latest?symbols=USD,GBP. If you click on the URL you will get below result: { "rates":{ "USD":1.1215, "GBP":0.9034 }, "base":"EUR", "date":"2019-07-17" } Reading and Parsing API response in Python: a. To handle API response will need two important libraries import requests import json b. Connect to the URL and get the response url = "https://api.exchangeratesapi.io/latest?symbols=USD,GBP" response = requests.get(url) c. Convert string to JSON format parsed = json.loads(data) d. Extract data and print date = parsed["date"] gbp_rate = parsed["rates"]["GBP"] usd_rate = parsed["rates"]["USD"] Here is the complete code: import requests import json url = "https://api.exchangeratesapi.io/latest?symbols=USD,GBP" response = requests.get(url) data = response.text parsed = json.loads(data) date = parsed["date"] gbp_rate = parsed["rates"]["GBP"] usd_rate = parsed["rates"]["USD"] print("On " + date + " EUR equals " + str(gbp_rate) + " GBP") print("On " + date + " EUR equals " + str(usd_rate) + " USD") Step 2: Preparing data received from API There are two ways to load data to BigQuery. You can save the received JSON formated data on JSON file and then load into BigQuery. You can parse the JSON object, convert JSON to dictionary object and then load into BigQuery. Step 3: Loading data into Google BigQuery We can load data into BigQuery directly using API call or can create CSV file and then load into BigQuery table. Create a Python script to extract data from API URL and load (UPSERT mode) into BigQuery table.Here UPSERT is nothing but Update and Insert operations. This means – if the target table has matching keys then update data, else insert a new record. import requests import json from google.cloud import bigquery url = "https://api.exchangeratesapi.io/latest?symbols=USD,GBP" response = requests.get(url) data = response.text parsed = json.loads(data) base = parsed["base"] date = parsed["date"] client = bigquery.Client() dataset_id = 'my_dataset' table_id = 'currency_details' table_ref = client.dataset(dataset_id).table(table_id) table = client.get_table(table_ref) for key, value in parsed.items(): if type(value) is dict: for currency, rate in value.items(): QUERY = ('SELECT target_currency FROM my_dataset.currency_details where currency=%', currency) query_job = client.query(QUERY) if query_job == 0: QUERY = ('update my_dataset.currency_details set rate = % where currency=%',rate, currency) query_job = client.query(QUERY) else: rows_to_insert = [ (base, currency, 1, rate) ] errors = client.insert_rows(table, rows_to_insert) assert errors == [] Load JSON file to BigQuery. You need to save the received data in JSON file and load JSON file to BigQuery table. import requests import json from google.cloud import bigquery url = "https://api.exchangeratesapi.io/latest?symbols=USD,GBP" response = requests.get(url) data = response.text parsed = json.loads(data) for key, value in parsed.items(): if type(value) is dict: with open('F:Pythondata.json', 'w') as f: json.dump(value, f) client = bigquery.Client(project="analytics-and-presentation") filename = 'F:Pythondata.json' dataset_id = ‘my_dayaset’' table_id = 'currency_rate_details' dataset_ref = client.dataset(dataset_id) table_ref = dataset_ref.table(table_id) job_config = bigquery.LoadJobConfig() job_config.source_format = bigquery.SourceFormat.NEWLINE_DELIMITED_JSON job_config.autodetect = True with open(filename, "rb") as source_file: job = client.load_table_from_file(source_file, table_ref, job_config=job_config) job.result() # Waits for table load to complete. print("Loaded {} rows into {}:{}.".format(job.output_rows, dataset_id, table_id)) Limitations of writing custom scripts and developing ETL to load data from API to BigQuery The above code is written based on the current source as well as target destination schema. If the data coming in is either from the source or the schema on BigQuery changes, ETL process will break. In case you need to clean your data from API – say transform time zones, hide personally identifiable information and so on, the current method does not support it. You will need to build another set of processes to accommodate that. Clearly, this would also need you to invest extra effort and money. You are at a serious risk of data loss if at any point your system breaks. This could be anything from source/destination not being reachable to script breaks and more. You would need to invest upfront in building systems and processes that capture all the fail points and consistently move your data to the destination. Since Python is an interpreted language, it might cause performance issue to extract from API and load data into BigQuery api. For many APIs, we would need to supply credentials to access API. It is a very poor practice to pass credentials as a plain text in Python script. You will need to take additional steps to ensure your pipeline is secure. API to BigQuery: Use Cases Advanced Analytics: BigQuery has powerful data processing capabilities that enable you to perform complex queries and data analysis on your API data. This way, you can extract insights that would not be possible within API alone. Data Consolidation: If you’re using multiple sources along with API, syncing them to BigQuery can help you centralize your data. This provides a holistic view of your operations, and you can set up a change data capture process to avoid discrepancies in your data. Historical Data Analysis: API has limits on historical data. However, syncing your data to BigQuery allows you to retain and analyze historical trends. Scalability: BigQuery can handle large volumes of data without affecting its performance. Therefore, it’s an ideal solution for growing businesses with expanding API data. Data Science and Machine Learning: You can apply machine learning models to your data for predictive analytics, customer segmentation, and more by having API data in BigQuery. Reporting and Visualization: While API provides reporting tools, data visualization tools like Tableau, PowerBI, and Looker (Google Data Studio) can connect to BigQuery, providing more advanced business intelligence options. If you need to convert an API table to a BigQuery table, Airbyte can do that automatically.

MongoDB is a popular NoSQL database that requires data to be modeled in JSON format. If your application’s data model has a natural fit to MongoDB’s recommended data model, it can provide good performance, flexibility, and scalability for transaction types of workloads. However, due to a few restrictions that you can face while analyzing data, it is highly recommended to stream data from MongoDB to BigQuery or any other data warehouse. MongoDB doesn’t have proper join, getting data from other systems to MongoDB will be difficult, and it also has no native support for SQL. MongoDB’s aggregation framework is not as easy to draft complex analytics logic as in SQL. The article provides steps to migrate data from MongoDB to BigQuery. It also talks about LIKE.TG Data, making it easier to replicate data. Therefore, without any further ado, let’s start learning about this MongoDB to BigQuery ETL. What is MongoDB? MongoDB is a popular NoSQL database management system known for its flexibility, scalability, and ease of use. It stores data in flexible, JSON-like documents, making it suitable for handling a variety of data types and structures.

Try our 14-day full-feature access free trial! Method 2: Manual Steps to Stream Data from MongoDB to BigQuery For the manual method, you will need some prerequisites, like: MongoDB environment: You should have a MongoDB account with a dataset and collection created in it. Tools like MongoDB compass and tool kit should be installed on your system. You should have access to MongoDB, including the connection string required to establish a connection using the command line. Google Cloud Environment Google Cloud SDK A Google Cloud project created with billing enabled Google Cloud Storage Bucket BigQuery API Enabled After meeting these requirements, you can manually export your data from MongoDB to BigQuery. Let’s get started! Step 1: Extract Data from MongoDB For the first step, you must extract data from your MongoDB account using the command line. To do this, you can use the mongoexport utility. Remember that mongoexport should be directly run on your system’s command-line window. An example of a command that you can give is: mongoexport --uri="mongodb+srv://username:[email protected]/database_name" --collection=collection_name --out=filename.file_format --fields="field1,field2…" Note: ‘username: password’ is your MongoDB username and password. ‘Cluster_name’ is the name of the cluster you created on your MongoDB account. It contains the database name (database_name) that contains the data you want to extract. The ‘–collection’ is the name of the table that you want to export. ‘–out=Filename.file_format’ is the file’s name and format in which you want to extract the data. For example, Comments.csv, the file with the extracted data, will be stored as a CSV file named comments. ‘– fields’ is applicable if you want to extract data in a CSV file format. After running this command, you will get a message like this displayed on your command prompt window: Connected to:mongodb+srv://[**REDACTED**]@cluster-name.gzjfolm.mongodb.net/database_name exported n records Here, n is just an example. When you run this command, it will display the number of records exported from your MongoDB collection. Step 2: Optional cleaning and transformations This is an optional step, depending on the type of data you have exported from MongoDB. When preparing data to be transferred from MongoDB to BigQuery, there are a few fundamental considerations to make in addition to any modifications necessary to satisfy your business logic. BigQuery processes UTF-8 CSV data. If your data is encoded in ISO-8859-1 (Latin-1), then you should specify that while loading it to BigQuery. BigQuery doesn’t enforce Primary key or Unique key Constraints, and the ETL (Extract, Transform, and Load) process should take care of that. Date values should be in the YYYY-MM-DD (Year-month-date) format and separated by dashes. Also, both platforms have different column types, which should be transformed for consistent and error-free data transfer.A few data types and their equivalents in BigQuery are as follows: These are just a few transformations you need to consider. Make the necessary translations before you load data to BigQuery. Step 3: Uploading data to Google Cloud Storage (GCS) After transforming your data, you must upload it to Google Cloud storage. The easiest way to do this is through your Google Cloud Web console. Login to your Google Cloud account and search for Buckets. Fill in the required fields and click Create. After creating the bucket, you will see your bucket listed with the rest. Select your bucket and click on the ‘upload files’ option. Select the file you exported from MongoDB in Step 1. Your MongoDB data is now uploaded to Google Cloud Storage. Step 4: Upload Data Extracted from MongoDB to BigQuery Table from GCS Now, from the left panel of Google Cloud, select BigQuery and select the project you are working on. Click on the three dots next to it and click ‘Create Dataset.’ Fill in all the necessary information and click the ‘Create Dataset’ button at the bottom. You have now created a dataset to store your exported data in. Now click on the three dots next to the dataset name you just created. Let’s say I created the dataset called mongo_to_bq. Select the ‘Create table’ option. Now, select the ‘Google Cloud Storage’ option and click the ‘browse’ option to select the dataset you created(mongo_to_bq). Fill in the rest of the details and click ‘Create Table’ at the bottom of the page. Now, your data has been transferred from MongoDB to BigQuery. Step 5: Verify Data Integrity After loading the data to BigQuery, it is essential to verify that the same data from MongoDB has been transferred and that no missing or corrupted data is loaded to BigQuery. To verify the data integrity, run some SQL queries in BigQuery UI and compare the records fetched as their result with your original MongoDB data to ensure correctness and completeness. Example: To find the locations of all the theaters in a dataset called “Theaters,” we can run the following query.

Every time fresh data enters MongoDB, this laborious procedure must be repeated. Potential for human error: There is a chance that data will be wrongly exported, uploaded to the wrong place, badly converted, or loaded to the wrong table or partition if error-prone manual procedures are followed at every stage. Data lags behind MongoDB: The data in BigQuery might not be current with the most recent inserts and changes in the MongoDB database due to the manual process’s latency. Recent modifications may be overlooked in important analyses. Difficult to incrementally add new data: When opposed to automatic streaming, which manages this effectively, adding just new or modified MongoDB entries manually is difficult. Hard to reprocess historical data: It would be necessary to manually export historical data from MongoDB and reload it into BigQuery if any problems were discovered in the datasets that were previously imported. No error handling: Without automated procedures to detect, manage, and retry mistakes and incorrect data, problems like network outages, data inaccuracies, or restrictions violations may arise. Scaling limitations: MongoDB’s exporting, uploading, and loading processes don’t scale properly and become increasingly difficult as data sizes increase. The constraints drive the requirement for automated MongoDB to BigQuery replication to create more dependable, scalable, and resilient data pipelines. MongoDB to BigQuery: Use Cases Streaming data from MongoDB to BigQuery may be very helpful in the following frequent use cases: Business analytics: Analysts may use BigQuery’s quick SQL queries, sophisticated analytics features, and smooth interaction with data visualization tools like Data Studio by streaming MongoDB data into BigQuery. This can lead to greater business insights. Data warehousing: By streaming data from MongoDB and merging it with data from other sources, businesses may create a cloud data warehouse on top of BigQuery, enabling corporate reporting and dashboards. Log analysis: BigQuery’s columnar storage and massively parallel processing capabilities enable the streaming of server, application, and clickstream logs from MongoDB databases for large-scale analytics. Data integration: By streaming to BigQuery as a centralised analytics data centre, businesses using MongoDB for transactional applications may integrate and analyse data from their relational databases, customer relationship management (CRM) systems, and third-party sources. Machine Learning: Streaming data from production MongoDB databases may be utilized to train ML models using BigQuery ML’s comprehensive machine learning features. Cloud migration: By gradually streaming data, move analytics from on-premises MongoDB to Google Cloud’s analytics and storage services.

It’s like ETL, but you load the data first and transform it into the target system. Tools for ELT include LIKE.TG Data, Azure Data Factory, Matillion, Apache Airflow, and IBM DataStage

var source_destination_email_banner = 'true'; Organizations often need to integrate data from various sources to gain valuable insights. One common scenario is transferring data from a NoSQL database like MongoDB to a cloud data warehouse like Snowflake for advanced analytics and business intelligence. However, this process can be challenging, especially for those new to data engineering. In this blog post, we’ll explore three easy methods to seamlessly migrate data from MongoDB to Snowflake, ensuring a smooth and efficient data integration process. Mongodb realtime replication to Snowflake ensures that data is consistently synchronized between MongoDB and Snowflake databases. Due to MongoDB’s schemaless nature, it becomes important to move the data to a warehouse-like Snowflake for meaningful analysis. In this article, we will discuss the different methods to migrate MongoDB to Snowflake.

Method 3: Using Native Cloud Tools and Snowpipe for MongoDB to Snowflake In this method, we’ll leverage native cloud tools and Snowpipe, a continuous data ingestion service, to load data from MongoDB into Snowflake. This approach eliminates the need for a separate ETL tool, streamlining the data transfer process. Introduction to MongoDB MongoDB is a popular NoSQL database management system designed for flexibility, scalability, and performance in handling unstructured or semistructured data. This document-oriented database presents a view wherein data is stored as flexible JSON-like documents instead of the traditional table-based relational databases. Data in MongoDB is stored in collections, which contain documents. Each document may have its own schema, which provides for dynamic and schema-less data storage. It also supports rich queries, indexing, and aggregation. Key Use Cases Real-time Analytics: You can leverage its aggregation framework and indexing capabilities to handle large volumes of data for real-time analytics and reporting. Personalization/Customization: It can efficiently support applications that require real-time personalization and recommendation engines by storing and querying user behavior and preferences. Introduction to Snowflake Snowflake is a fully managed service that provides customers with near-infinite scalability of concurrent workloads to easily integrate, load, analyze, and securely share their data. Its common applications include data lakes, data engineering, data application development, data science, and secure consumption of shared data. Snowflake’s unique architecture natively integrates computing and storage. This architecture enables you to virtually enable your users and data workloads to access a single copy of your data without any detrimental effect on performance. With Snowflake, you can seamlessly run your data solution across multiple regions and Clouds for a consistent experience. Snowflake makes it possible by abstracting the complexity of underlying Cloud infrastructures. Advantages of Snowflake Scalability: Using Snowflake, you can automatically scale the compute and storage resources to manage varying workloads without any human intervention. Supports Concurrency: Snowflake delivers high performance when dealing with multiple users supporting mixed workloads without performance degradation.

Method 2: Writing Custom Scripts to Move Data from MongoDB to Snowflake Below is a quick snapshot of the broad framework to move data from MongoDB to Snowflake using custom code. The steps are: Step 1:Extracting data from MongoDB Collections Step 2: Optional Data Type conversions and Data Formatting Step 3: Staging Data Files Step 4: Copying Staged Files to Snowflake Table Step 5: Migrating to Snowflake Let’s take a detailed look at all the required steps for MongoDB Snowflake Integration: Migrate your data seamlessly [email protected]"> No credit card required Step 1:Extracting data from MongoDB Collections mongoexport is the utility coming with MongoDB which can be used to create JSON or CSV export of the data stored in any MongoDB collection. The following points are to be noted while using mongoexport : mongoexport should be running directly in the system command line, not from the Mongo shell (the mongo shell is the command-line tool used to interact with MongoDB) That the connecting user should have at least the read role on the target database. Otherwise, a permission error will be thrown. mongoexport by default uses primary read (direct read operations to the primary member in a replica set) as the read preference when connected to mongos or a replica set. Also, note that the default read preference which is “primary read” can be overridden using the –readPreference option Below is an example showing how to export data from the collection named contact_coln to a CSV file in the location /opt/exports/csv/col_cnts.csv mongoexport --db users --collection contact_coln --type=csv --fields empl_name,empl_address --out /opt/exports/csv/empl_contacts.csv To export in CSV format, you should specify the column names in the collection to be exported. The above example specifies the empl_name and empl_address fields to export. The output would look like this: empl_name, empl_address Prasad, 12 B street, Mumbai Rose, 34544 Mysore You can also specify the fields to be exported in a file as a line-separated list of fields to export – with one field per line. For example, you can specify the emplyee_name and employee_address fields in a file empl_contact_fields.txt : empl_name, empl_address Then, applying the –fieldFile option, define the fields to export with the file: mongoexport --db users --collection contact_coln --type=csv --fieldFile empl_contact_fields.txt --out /opt/backups/emplyee_contacts.csv Exported CSV files will have field names as a header by default. If you don’t want a header in the output file,–noHeaderLine option can be used. As in the above example –fields can be used to specify fields to be exported. It can also be used to specify nested fields. Suppose you have post_code filed with employee_address filed, it can be specified as employee_address.post_code Incremental Data Extract From MongoDB So far we have discussed extracting an entire MongoDB collection. It is also possible to filter the data while extracting from the collection by passing a query to filter data. This can be used for incremental data extraction. –query or -q is used to pass the query.For example, let’s consider the above-discussed contacts collection. Suppose the ‘updated_time’ field in each document stores the last updated or inserted Unix timestamp for that document. mongoexport -d users -c contact_coln -q '{ updated_time: { $gte: 154856788 } }' --type=csv --fieldFile employee_contact_fields.txt --out exportdir/emplyee_contacts.csv The above command will extract all records from the collection with updated_time greater than the specified value,154856788. You should keep track of the last pulled updated_time separately and use that value while fetching data from MongoDB each time. Step 2: Optional Data Type conversions and Data Formatting Along with the application-specific logic to be applied while transferring data, the following are to be taken care of when migrating data to Snowflake. Snowflake can support many of the character sets including UTF-8. For the full list of supported encodings please visit here. If you have worked with cloud-based data warehousing solutions before, you might have noticed that most of them lack support constraints and standard SQL constraints like UNIQUE, PRIMARY KEY, FOREIGN KEY, NOT NULL. However, keep in mind that Snowflake supports most of the SQL constraints. Snowflake data types cover all basic and semi-structured types like arrays. It also has inbuilt functions to work with semi-structured data. The below list shows Snowflake data types compatible with the various MongoDB data types. As you can see from this table of MongoDB vs Snowflake data types, while inserting data, Snowflake allows almost all of the date/time formats. You can explicitly specify the format while loading data with the help of the File Format Option. We will discuss this in detail later. The full list of supported date and time formats can be found here. Step 3: Staging Data Files If you want to insert data into a Snowflake table, the data should be uploaded to online storage like S3. This process is called staging. Generally, Snowflake supports two types of stages – internal and external. Internal Stage For every user and table, Snowflake will create and allocate a staging location that is used by default for staging activities and those stages are named using some conventions as mentioned below. Note that is also possible to create named internal stages. The user stage is named ‘@~’ The name of the table stage is the name of the table. The user or table stages can’t be altered or dropped. It is not possible to set file format options in the default user or table stages. Named internal stages can be created explicitly using SQL statements. While creating named internal stages, file format, and other options can be set which makes loading data to the table very easy with minimal command options. SnowSQL comes with a lightweight CLI client which can be used to run commands like DDLs or data loads. This is available in Linux/Mac/Windows. Read more about the tool and options here. Below are some example commands to create a stage: Create a names stage: create or replace stage my_mongodb_stage copy_options = (on_error='skip_file') file_format = (type = 'CSV' field_delimiter = '|' skip_header = 2); The PUT command is used to stage data files to an internal stage. The syntax is straightforward – you only need to specify the file path and stage name : PUT file://path_to_file/filename internal_stage_name Eg: Upload a file named emplyee_contacts.csv in the /tmp/mongodb_data/data/ directory to an internal stage named mongodb_stage put file:////tmp/mongodb_data/data/emplyee_contacts.csv @mongodb_stage; There are many configurations to be set to maximize data load spread while uploading the file like the number of parallelisms, automatic compression of data files, etc. More information about those options is listed here. External Stage AWS and Azure are the industry leaders in the public cloud market. It does not come as a surprise that Snowflake supports both Amazon S3 and Microsoft Azure for external staging locations. If the data is in S3 or Azure, all you need to do is create an external stage to point that and the data can be loaded to the table. To create an external stage on S3, IAM credentials are to be specified. If the data in S3 is encrypted, encryption keys should also be given. create or replace stage mongod_ext_stage url='s3://snowflake/data/mongo/load/files/' credentials=(aws_key_id='181a233bmnm3c' aws_secret_key='a00bchjd4kkjx5y6z'); encryption=(master_key = 'e00jhjh0jzYfIjka98koiojamtNDwOaO8='); Data to the external stage can be uploaded using respective cloud web interfaces or provided SDKs or third-party tools. Step 4: Copying Staged Files to Snowflake Table COPY INTO is the command used to load data from the stage area into the Snowflake table. Compute resources needed to load the data are supplied by virtual warehouses and the data loading time will depend on the size of the virtual warehouses Eg: To load from a named internal stage copy into mongodb_internal_table from @mngodb_stage; To load from the external stage :(Here only one file is specified) copy into mongodb_external_stage_table from @mongodb_ext_stage/tutorials/dataloading/employee_contacts_ext.csv; To copy directly from an external location without creating a stage: copy into mongodb_table from s3://mybucket/snow/mongodb/data/files credentials=(aws_key_id='$AWS_ACCESS_KEY_ID' aws_secret_key='$AWS_SECRET_ACCESS_KEY') encryption=(master_key = 'eSxX0jzYfIdsdsdsamtnBKOSgPH5r4BDDwOaO8=') file_format = (format_name = csv_format); The subset of files can be specified using patterns copy into mongodb_table from @mongodb_stage file_format = (type = 'CSV') pattern='.*/.*/.*[.]csv[.]gz'; Some common format options used in COPY command for CSV format : COMPRESSION – Compression used for the input data files. RECORD_DELIMITER – The character used as records or lines separator FIELD_DELIMITER -Character used for separating fields in the input file. SKIP_HEADER – Number of header lines to skip while loading data. DATE_FORMAT – Used to specify the date format TIME_FORMAT – Used to specify the time format The full list of options is given here. Download the Cheatsheet on How to Set Up ETL to Snowflake Learn the best practices and considerations for setting up high-performance ETL to Snowflake Step 5: Migrating to Snowflake While discussing data extraction from MongoDB both full and incremental methods are considered. Here, we will look at how to migrate that data into Snowflake effectively. Snowflake’s unique architecture helps to overcome many shortcomings of existing big data systems. Support for row-level updates is one such feature. Out-of-the-box support for the row-level updates makes delta data load to the Snowflake table simple. We can extract the data incrementally, load it into a temporary table and modify records in the final table as per the data in the temporary table. There are three popular methods to update the final table with new data after new data is loaded into the intermediate table. Update the rows in the final table with the value in a temporary table and insert new rows from the temporary table into the final table. UPDATE final_mongodb_table t SET t.value = s.value FROM intermed_mongdb_table in WHERE t.id = in.id; INSERT INTO final_mongodb_table (id, value) SELECT id, value FROM intermed_mongodb_table WHERE NOT id IN (SELECT id FROM final_mongodb_table); 2. Delete all rows from the final table which are also present in the temporary table. Then insert all rows from the intermediate table to the final table. DELETE .final_mogodb_table f WHERE f.id IN (SELECT id from intermed_mongodb_table); INSERT final_mongodb_table (id, value) SELECT id, value FROM intermed_mongodb_table; 3. MERGE statement – Using a single MERGE statement both inserts and updates can be carried out simultaneously. We can use this option to apply changes to the temporary table. MERGE into final_mongodb_table t1 using tmp_mongodb_table t2 on t1.key = t2.key WHEN matched then update set value = t2.value WHEN not matched then INSERT (key, value) values (t2.key, t2.value); Limitations of using Custom Scripts to Connect MongoDB to Snowflake Even though the manual method will get your work done but you might face some difficulties while doing it. I have listed below some limitations that might hinder your data migration process: If you want to migrate data from MongoDB to Snowflake in batches, then this approach works decently well. However, if you are looking for real-time data availability, this approach becomes extremely tedious and time-consuming. With this method, you can only move data from one place to another, but you cannot transform the data when in transit. When you write code to extract a subset of data, those scripts often break as the source schema keeps changing or evolving. This can result in data loss. The method mentioned above has a high scope of errors. This might impact Snowflake’s availability and accuracy of data. Method 3: Using Native Cloud Tools and Snowpipe for MongoDB to Snowflake Snowpipe, provided by Snowflake, enables a shift from the traditional scheduled batch loading jobs to a more dynamic approach. It supersedes the conventional SQL COPY command, facilitating near real-time data availability. Essentially, Snowpipe imports data into a staging area in smaller increments, working in tandem with your cloud provider’s native services, such as AWS or Azure. For illustration, consider these scenarios for each cloud provider, detailing the integration of your platform’s infrastructure and the transfer of data from MongoDB to a Snowflake warehouse: AWS: Utilize a Kinesis delivery stream to deposit MongoDB data into an S3 bucket. With an active SNS system, the associated successful run ID can be leveraged to import data into Snowflake using Snowpipe. Azure: Activate Snowpipe with an Event Grid message corresponding to Blob storage events. Your MongoDB data is initially placed into an external Azure stage. Upon creating a blob storage event message, Snowpipe is alerted via Event Grid when the data is primed for Snowflake insertion. Subsequently, Snowpipe transfers the queued files into a pre-established table in Snowflake. For comprehensive guidance, Snowflake offers a detailed manual on the setup. Limitations of Using Native Cloud Tools and Snowpipe A deep understanding of NoSQL databases, Snowflake, and cloud services is crucial. Troubleshooting in a complex data pipeline environment necessitates significant domain knowledge, which may be challenging for smaller or less experienced data teams. Long-term management and ownership of the approach can be problematic, as the resources used are often controlled by teams outside the Data department. This requires careful coordination with other engineering teams to establish clear ownership and ongoing responsibilities. The absence of native tools for applying schema to NoSQL data presents difficulties in schematizing the data, potentially reducing its value in the data warehouse. MongoDB to Snowflake: Use Cases Snowflake’s system supports JSON natively, which is central to MongoDB’s document model. This allows direct loading of JSON data into Snowflake without needing to convert it into a fixed schema, eliminating the need for an ETL pipeline and concerns about evolving data structures. Snowflake’s architecture is designed for scalability and elasticity online. It can handle large volumes of data at varying speeds without resource conflicts with analytics, supporting micro-batch loading for immediate data analysis. Scaling up a virtual warehouse can speed up data loading without causing downtime or requiring data redistribution. Snowflake’s core is a powerful SQL engine that works seamlessly with BI and analytics tools. Its SQL capabilities extend beyond relational data, enabling access to MongoDB’s JSON data, with its variable schema and nested structures, through SQL. Snowflake’s extensions and the creation of relational views make this JSON data readily usable with SQL-based tools.

However, the choice of migration method can impact the process’s efficiency and complexity. Using custom scripts or Snowpipe for data ingestion may require extensive manual effort, face challenges with data consistency and real-time updates, and demand specialized technical skills. For using the Native Cloud Tools, you will need a deep understanding of NoSQL databases, Snowflake, and cloud services. Moreover, troubleshooting can also be troublesome in such an environment.

SIGN UP HERE FOR A 14-DAY FREE TRIAL Method 2: Manual ETL Process to Connect MySQL to BigQuery The manual method of connecting MySQL to BigQuery involves writing custom ETL scripts to set up this data transfer process. This method can be implemented in 2 different forms: Full Dump and Load Incremental Dump and Load 1. Full Dump and Load This approach is relatively simple, where complete data from the source MySQL table is extracted and migrated to BigQuery. If the target table already exists, drop it and create a new table ( Or delete complete data and insert newly extracted data). Full Dump and Load is the only option for the first-time load even if the incremental load approach is used for recurring loads. The full load approach can be followed for relatively small tables even for further recurring loads. You can also check out MySQL to Redshift integration. The high-level steps to be followed to replicate MySQL to BigQuery are: Step 1: Extract Data from MySQL Step 2: Clean and Transform the Data Step 3: Upload to Google Cloud Storage(GCS) Step 4: Upload to the BigQuery Table from GCS Let’s take a detailed look at each step to migrate sqlite to mariadb. Step 1: Extract Data from MySQL There are 2 popular ways to extract data from MySQL – using mysqldump and using SQL query. Extract data using mysqldump Mysqldump is a client utility coming with Mysql installation. It is mainly used to create a logical backup of a database or table. Here, is how it can be used to extract one table: mysqldump -u <db_username> -h <db_host> -p db_name table_name > table_name.sql Here output file table_name.sql will be in the form of insert statements like INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...); This output has to be converted into a CSV file. You have to write a small script to perform this. Here is a well-accepted python library doing the same – mysqldump_to_csv.py Alternatively, you can create a CSV file using the below command. However, this option works only when mysqldump is run on the same machine as the mysqld server which is not the case normally. mysqldump -u [username] -p -t -T/path/to/directory [database] --fields-terminated-by=, Extract Data using SQL query MySQL client utility can be used to run SQL commands and redirect output to file. mysql -B -u user database_name -h mysql_host -e "select * from table_name;" > table_name_data_raw.txt Further, it can be piped with text editing utilities like sed or awk to clean and format data. Example: mysql -B -u user database_name -h mysql_host -e "select * from table_name;" | sed "s/'/'/;s/t/","/g;s/^/"/;s/$/"/;s/n//g" > table_name_data.csv Step 2: Clean and Transform the Data Apart from transforming data for business logic, there are some basic things to keep in mind: BigQuery expects CSV data to be UTF-8 encoded. BigQuery does not enforce Primary Key and unique key constraints. ETL process has to take care of that. Column types are slightly different. Most of the types have either equivalent or convertible types. Here is a list of common data types. Fortunately, the default date format in MySQL is the same, YYYY-MM-DD. Hence, while taking mysqldump there is no need to do any specific changes for this. If you are using a string field to store date and want to convert to date while moving to BigQuery you can use STR_TO_DATE function.DATE value must be dash(-) separated and in the form YYYY-MM-DD (year-month-day). You can visit theirofficial page to know more about BigQuery data types. Syntax : STR_TO_DATE(str,format) Example : SELECT STR_TO_DATE('31,12,1999','%d,%m,%Y'); Result : 1999-12-31 The hh:mm: ss (hour-minute-second) portion of the timestamp must use a colon (:) separator. Make sure text columns are quoted if it can potentially have delimiter characters. Step 3: Upload to Google Cloud Storage(GCS) Gsutil is a command-line tool for manipulating objects in GCS. It can be used to upload files from different locations to your GCS bucket. To copy a file to GCS: gsutil cp table_name_data.csv gs://my-bucket/path/to/folder/ To copy an entire folder: gsutil cp -r dir gs://my-bucket/path/to/parent/ If the files are present in S3, the same command can be used to transfer to GCS. gsutil cp -R s3://bucketname/source/path gs://bucketname/destination/path Storage Transfer Service Storage Transfer Service from Google cloud is another option to upload files to GCS from S3 or other online data sources like HTTP/HTTPS location. Destination or sink is always a Cloud Storage bucket. It can also be used to transfer data from one GCS bucket to another. This service is extremely handy when comes to data movement to GCS with support for: Schedule one-time or recurring data transfer. Delete existing objects in the destination if no corresponding source object is present. Deletion of source object after transferring. Periodic synchronization between source and sink with advanced filters based on file creation dates, file name, etc. Upload from Web Console If you are uploading from your local machine, web console UI can also be used to upload files to GCS. Here are the steps to upload a file to GCS with screenshots. Login to your GCP account. In the left bar, click Storage and go to Browser. 2. Select the GCS bucket you want to upload the file.Here the bucket we are using is test-data-LIKE.TG . Click on the bucket. 3. On the bucket details page below, click the upload files button and select file from your system. 4. Wait till the upload is completed. Now, the uploaded file will be listed in the bucket: Step 4: Upload to the BigQuery Table from GCS You can use the bq command to interact with BigQuery. It is extremely convenient to upload data to the table from GCS.Use the bq load command, and specify CSV as the source_format. The general syntax of bq load: bq --location=[LOCATION] load --source_format=[FORMAT] [DATASET].[TABLE] [PATH_TO_SOURCE] [SCHEMA] [LOCATION] is your location. This is optional.[FORMAT] is CSV.[DATASET] is an existing dataset.[TABLE] is the name of the table into which you’re loading data.[PATH_TO_SOURCE] is a fully-qualified Cloud Storage URI.[SCHEMA] is a valid schema. The schema can be a local JSON file or inline.– autodetect flag also can be used instead of supplying a schema definition. There are a bunch of options specific to CSV data load : To see full list options visit Bigquery documentation on loading data cloud storage CSV, visit here. Following are some example commands to load data: Specify schema using a JSON file: bq --location=US load --source_format=CSV mydataset.mytable gs://mybucket/mydata.csv ./myschema.json If you want schema auto-detected from the file: bq --location=US load --autodetect --source_format=CSV mydataset.mytable gs://mybucket/mydata.csv If you are writing to the existing table, BigQuery provides three options – Write if empty, Append to the table, Overwrite table. Also, it is possible to add new fields to the table while uploading data. Let us see each with an example. To overwrite the existing table: bq --location=US load --autodetect --replace --source_format=CSV mydataset.mytable gs://mybucket/mydata.csv To append to an existing table: bq --location=US load --autodetect --noreplace --source_format=CSV mydataset.mytable gs://mybucket/mydata.csv ./myschema.json To add a new field to the table. Here new schema file with an extra field is given : bq --location=asia-northeast1 load --noreplace --schema_update_option=ALLOW_FIELD_ADDITION --source_format=CSV mydataset.mytable gs://mybucket/mydata.csv ./myschema.json 2. Incremental Dump and Load In certain use cases, loading data once from MySQL to BigQuery will not be enough. There might be use cases where once initial data is extracted from the source, we need to keep the target table in sync with the source. For a small table doing a full data dump every time might be feasible but if the volume data is higher, we should think of a delta approach. The following steps are used in the Incremental approach to connect MySQL to Bigquery: Step 1: Extract Data from MySQL Step 2: Update Target Table in BigQuery Step 1: Extract Data from MySQL For incremental data extraction from MySQL use SQL with proper predicates and write output to file. mysqldump cannot be used here as it always extracts full data. Eg: Extracting rows based on the updated_timestamp column and converting to CSV. mysql -B -u user database_name -h mysql_host -e "select * from table_name where updated_timestamp < now() and updated_timestamp >'#max_updated_ts_in_last_run#'"| sed "s/'/'/;s/t/","/g;s/^/"/;s/$/"/;s/n//g" > table_name_data.csv Note: In case of any hard delete happened in the source table, it will not be reflected in the target table. Step 2: Update Target Table in BigQuery First, upload the data into a staging table to upsert newly extracted data to the BigQuery table. This will be a full load. Please refer full data load section above. Let’s call it delta_table. Now there are two approaches to load data to the final table: Update the values existing records in the final table and insert new rows from the delta table which are not in the final table. UPDATE data_set.final_table t SET t.value = s.value FROM data_set.delta_table s WHERE t.id = s.id; INSERT data_set.final_table (id, value) SELECT id, value FROM data_set.delta_table WHERE NOT id IN (SELECT id FROM data_set.final_table); 2. Delete rows from the final table which are present in the delta table. Then insert all rows from the delta table to the final table. DELETE data_set.final_table f WHERE f.id IN (SELECT id from data_set.delta_table); INSERT data_set.final_table (id, value) SELECT id, value FROM data_set.delta_table; Disadvantages of Manually Loading Data Manually loading data from MySQL to BigQuery presents several drawbacks: Cumbersome Process: While custom code suits one-time data movements, frequent updates become burdensome manually, leading to inefficiency and bulkiness. Data Consistency Issues: BigQuery lacks guaranteed data consistency for external sources, potentially causing unexpected behavior during query execution amidst data changes. Location Constraint: The data set’s location must align with the Cloud Storage Bucket’s region or multi-region, restricting flexibility in data storage. Limitation with CSV Format: CSV files cannot accommodate nested or repeated data due to format constraints, limiting data representation possibilities. File Compression Limitation: Mixing compressed and uncompressed files in the same load job using CSV format is not feasible, adding complexity to data loading tasks. File Size Restriction: The maximum size for a gzip file in CSV format is capped at 4 GB, potentially limiting the handling of large datasets efficiently. What Can Be Migrated From MySQL To BigQuery? Since the 1980s, MySQL has been the most widely used open-source relational database management system (RDBMS), with businesses of all kinds using it today. MySQL is fundamentally a relational database. It is renowned for its dependability and speedy performance and is used to arrange and query data in systems of rows and columns. Both MySQL and BigQuery use tables to store their data. When you migrate a table from MySQL to BigQuery, it is stored as a standard, or managed, table. Both MySQL and BigQuery employ SQL, but they accept distinct data types, therefore you’ll need to convert MySQL data types to BigQuery equivalents. Depending on the data pipeline you utilize, there are several options for dealing with this. Once in BigQuery, the table is encrypted and kept in Google’s warehouse. Users may execute complicated queries or accomplish any BigQuery-enabled job. The Advantages of Connecting MySQL To BigQuery BigQuery is intended for efficient and speedy analytics, and it does so without compromising operational workloads, which you will most likely continue to manage in MySQL. It improves workflows and establishes a single source of truth. Switching between platforms can be difficult and time-consuming for analysts. Updating BigQuery with MySQL ensures that both data storage systems are aligned around the same source of truth and that other platforms, whether operational or analytical, are constantly bringing in the right data. BigQuery increases data security. By replicating data from MySQL to BigQuery, customers avoid the requirement to provide rights to other data engineers on operational systems. BigQuery handles Online Analytical Processing (OLAP), whereas MySQL is designed for Online Transaction Processing (OLTP). Because it is a cost-effective, serverless, and multi-cloud data warehouse, BigQuery can deliver deeper data insights and aid in the conversion of large data into useful insights. Conclusion The article listed 2 methods to set up your BigQuery MySQL integration. The first method relies on LIKE.TG ’s automated Data Pipeline to transfer data, while the second method requires you to write custom scripts to perform ETL processes from MySQL to BigQuery. Complex analytics on data requires moving data to Data Warehouses like BigQuery. It takes multiple steps to extract data, clean it and upload it. It requires real effort to ensure there is no data loss at each stage of the process, whether it happens due to data anomalies or type mismatches.

var source_destination_email_banner = 'true'; Migrating from Oracle to Snowflake? This guide outlines two straightforward methods to move your data. Learn how to leverage Snowflake’s cloud architecture to access insights from your Oracle databases.Ultimately, you can choose the best of both methods based on your business requirements. Read along to learn how to migrate data seamlessly from Oracle to Snowflake. Overview of Oracle Oracle Database is a robust relational database management system (RDBMS) known for its scalability, reliability, and advanced features like high availability and security. Oracle offers an integrated portfolio of cloud services featuring IaaS, PaaS, and SaaS, posing competition to big cloud providers. The company also designs and markets enterprise software solutions in the areas of ERP, CRM, SCM, and HCM, addressing a wide range of industries such as finance, health, and telecommunication institutions. Overview of Snowflake Snowflake is a cloud-based data warehousing platform designed for modern data analytics and processing. Snowflake separates compute, storage, and services. Therefore, they may scale independently with a SQL data warehouse for querying and analyzing structured and semi-structured data stored in Amazon S3 or Azure Blob Storage. Advantages of Snowflake Scalability: Using Snowflake, you can automatically scale the compute and storage resources to manage varying workloads without any human intervention. Supports Concurrency: Snowflake delivers high performance when dealing with multiple users supporting mixed workloads without performance degradation. Efficient Performance: You can achieve optimized query performance through the unique architecture of Snowflake, with particular techniques applied in columnar storage, query optimization, and caching. Why Choose Snowflake over Oracle? Here, I have listed some reasons why Snowflake is chosen over Oracle. Scalability and Flexibility: Snowflake is intrinsically designed for the cloud to deliver dynamic scalability with near-zero manual tuning or infrastructure management. Horizontal and vertical scaling can be more complex and expensive in traditional Oracle on-premises architecture. Concurrency and Performance: Snowflake’s architecture supports automatic and elastic scaling, ensuring consistent performance even under heavy workloads. Whereas Oracle’s monolithic architecture may struggle with scalability and concurrency challenges as data volumes grow. Ease of Use: Snowflake’s platform is known for its simplicity and ease of use. Although quite robust, Oracle normally requires specialized skills and resources in configuration, management, and optimization. Common Challenges of Migration from Oracle to Snowflake Let us also discuss what are the common challenges you might face while migrating your data from Oracle to Snowflake. Architectural Differences: Oracle has a traditional on-premises architecture, while Snowflake has a cloud-native architecture. This makes the adaptation of existing applications and workflows developed for one environment into another quite challenging. Compatibility Issues: There are differences in SQL dialects, data types, and procedural languages between Oracle and Snowflake that will have to be changed in queries, scripts, and applications to be migrated for compatibility and optimal performance. Performance Tuning: Optimizing performance in Snowflake to Oracle’s performance levels at a minimum requires knowledge of Snowflake’s capabilities and the tuning configurations it offers, among many other special features such as clustering keys and auto-scaling. Integrate Oracle with Snowflake in a hassle-free manner. Method 1: Using LIKE.TG Data to Set up Oracle to Snowflake Integration Using LIKE.TG Data, a No-code Data Pipeline, you can directly transfer data from Oracle to Snowflake and other Data Warehouses, BI tools, or a destination of your choice in a completely hassle-free automated manner. Method 2: Manual ETL Process to Set up Oracle to Snowflake Integration In this method, you can convert your Oracle data to a CSV file using SQL plus and then transform it according to the compatibility. You then can stage the files in S3 and ultimately load them into Snowflake using the COPY command. This method can be time taking and can lead to data inconsistency.

Integrate Oracle to SnowflakeGet a DemoTry itIntegrate Oracle to BigQueryGet a DemoTry itIntegrate Oracle to PostgreSQLGet a DemoTry it Method 2: Manual ETL Process to Set up Oracle to Snowflake Integration Oracle and Snowflake are two distinct data storage options since their structures are very dissimilar. Although there is no direct way to load data from Oracle to Snowflake, using a mediator that connects to both Oracle and Snowflake can ease the process. Steps to move data from Oracle to Snowflake can be categorized as follows: Step 1: Extract Data from Oracle to CSV using SQL*Plus Step 2: Data Type Conversion and Other Transformations Step 3: Staging Files to S3 Step 4: Finally, Copy Staged Files to the Snowflake Table Let us go through these steps to connect Oracle to Snowflake in detail. Step 1: Extract data from Oracle to CSV using SQL*Plus SQL*Plus is a query tool installed with every Oracle Database Server or Client installation. It can be used to query and redirect the result of an SQL query to a CSV file. The command used for this is: Spool Eg : -- Turn on the spool spool spool_file.txt -- Run your Query select * from dba_table; -- Turn of spooling spool off; The spool file will not be visible until the command is turned off If the Spool file doesn’t exist already, a new file will be created. If it exists, it will be overwritten by default. There is an append option from Oracle 10g which can be used to append to an existing file. Most of the time the data extraction logic will be executed in a Shell script. Here is a very basic example script to extract full data from an Oracle table: #!/usr/bin/bash FILE="students.csv" sqlplus -s user_name/password@oracle_db <<EOF SET PAGESIZE 35000 SET COLSEP "|" SET LINESIZE 230 SET FEEDBACK OFF SPOOL $FILE SELECT * FROM EMP; SPOOL OFF EXIT EOF#!/usr/bin/bash FILE="emp.csv" sqlplus -s scott/tiger@XE <<EOF SET PAGESIZE 50000 SET COLSEP "," SET LINESIZE 200 SET FEEDBACK OFF SPOOL $FILE SELECT * FROM STUDENTS; SPOOL OFF EXIT EOF SET PAGESIZE – The number of lines per page. The header line will be there on every page. SET COLSEP – Setting the column separator. SET LINESIZE – The number of characters per line. The default is 80. You can set this to a value in a way that the entire record comes within a single line. SET FEEDBACK OFF – In order to prevent logs from appearing in the CSV file, the feedback is put off. SPOOL $FILE – The filename where you want to write the results of the query. SELECT * FROM STUDENTS – The query to be executed to extract data from the table. SPOOL OFF – To stop writing the contents of the SQL session to the file. Incremental Data Extract As discussed in the above section, once Spool is on, any SQL can be run and the result will be redirected to the specified file. To extract data incrementally, you need to generate SQL with proper conditions to select only records that are modified after the last data pull. Eg: select * from students where last_modified_time > last_pull_time and last_modified_time <= sys_time. Now the result set will have only changed records after the last pull.

Apart from such use case-specific changes, there are certain important things to be noted for smooth data movement. Also, check out Oracle to MySQL Integration. Many errors can be caused by character sets mismatch in source and target. Note that Snowflake supports all major character sets including UTF-8 and UTF-16. The full list can be found here. While moving data from Oracle to Big Data systems most of the time data integrity might be compromised due to lack of support for SQL constraints. Fortunately, Snowflake supports all SQL constraints like UNIQUE, PRIMARY KEY, FOREIGN KEY, NOT NULL constraints which is a great help for making sure data has moved as expected. Snowflake’s type system covers most primitive and advanced data types which include nested data structures like struct and array. Below is the table with information on Oracle data types and the corresponding Snowflake counterparts. Often, date and time formats require a lot of attention while creating data pipelines. Snowflake is quite flexible here as well. If a custom format is used for dates or times in the file to be inserted into the table, this can be explicitly specified using “File Format Option”. The complete list of date and time formats can be found here. Step 3: Stage Files to S3 To load data from Oracle to Snowflake, it has to be uploaded to a cloud staging area first. If you have your Snowflake instance running on AWS, then the data has to be uploaded to an S3 location that Snowflake has access to. This process is called staging. The snowflake stage can be either internal or external. Internal Stage If you chose to go with this option, each user and table will be automatically assigned to an internal stage which can be used to stage data related to that user or table. Internal stages can be even created explicitly with a name. For a user, the default internal stage will be named as ‘@~’. For a table, the default internal stage will have the same name as the table. There is no option to alter or drop an internal default stage associated with a user or table. Unlike named stages file format options cannot be set to default user or table stages. If an internal stage is created explicitly by the user using SQL statements with a name, many data loading options can be assigned to the stage like file format, date format, etc. When data is loaded to a table through this stage those options are automatically applied. Note: The rest of this document discusses many Snowflake commands. Snowflake comes with a very intuitive and stable web-based interface to run SQL and commands. However, if you prefer to work with a lightweight command-line utility to interact with the database you might like SnowSQL – a CLI client available in Linux/Mac/Windows to run Snowflake commands. Read more about the tool and options here. Now let’s have a look at commands to create a stage: Create a named internal stage my_oracle_stage and assign some default options: create or replace stage my_oracle_stage copy_options= (on_error='skip_file') file_format= (type = 'CSV' field_delimiter = ',' skip_header = 1); PUT is the command used to stage files to an internal Snowflake stage. The syntax of the PUT command is: PUT file://path_to_your_file/your_filename internal_stage_name Eg: Upload a file items_data.csv in the /tmp/oracle_data/data/ directory to an internal stage named oracle_stage. put file:////tmp/oracle_data/data/items_data.csv @oracle_stage; While uploading the file you can set many configurations to enhance the data load performance like the number of parallelisms, automatic compression, etc. Complete information can be found here. External Stage Let us now look at the external staging option and understand how it differs from the internal stage. Snowflake supports any accessible Amazon S3 or Microsoft Azure as an external staging location. You can create a stage to pointing to the location data that can be loaded directly to the Snowflake table through that stage. No need to move the data to an internal stage. If you want to create an external stage pointing to an S3 location, IAM credentials with proper access permissions are required. If data needs to be decrypted before loading to Snowflake, proper keys are to be provided. Here is an example to create an external stage: create or replace stage oracle_ext_stage url='s3://snowflake_oracle/data/load/files/' credentials=(aws_key_id='1d318jnsonmb5#dgd4rrb3c' aws_secret_key='aii998nnrcd4kx5y6z'); encryption=(master_key = 'eSxX0jzskjl22bNaaaDuOaO8='); Once data is extracted from Oracle it can be uploaded to S3 using the direct upload option or using AWS SDK in your favorite programming language. Python’s boto3 is a popular one used under such circumstances. Once data is in S3, an external stage can be created to point to that location. Step 4: Copy staged files to Snowflake table So far – you have extracted data from Oracle, uploaded it to an S3 location, and created an external Snowflake stage pointing to that location. The next step is to copy data to the table. The command used to do this is COPY INTO. Note: To execute the COPY INTO command, compute resources in Snowflake virtual warehouses are required and your Snowflake credits will be utilized. Eg: To load from a named internal stage copy into oracle_table from @oracle_stage; Loading from the external stage. Only one file is specified. copy into my_ext_stage_table from @oracle_ext_stage/tutorials/dataloading/items_ext.csv; You can even copy directly from an external location without creating a stage: copy into oracle_table from s3://mybucket/oracle_snow/data/files credentials=(aws_key_id='$AWS_ACCESS_KEY_ID' aws_secret_key='$AWS_SECRET_ACCESS_KEY') encryption=(master_key = 'eSxX009jhh76jkIuLPH5r4BD09wOaO8=') file_format = (format_name = csv_format); Files can be specified using patterns copy into oracle_pattern_table from @oracle_stage file_format = (type = 'TSV') pattern='.*/.*/.*[.]csv[.]gz'; Some commonly used options for CSV file loading using the COPY command are: DATE_FORMAT – Specify any custom date format you used in the file so that Snowflake can parse it properly. TIME_FORMAT – Specify any custom date format you used in the file. COMPRESSION – If your data is compressed, specify algorithms used to compress. RECORD_DELIMITER – To mention lines separator character. FIELD_DELIMITER – To indicate the character separating fields in the file. SKIP_HEADER – This is the number of header lines to skipped while inserting data into the table. Update Snowflake Table We have discussed how to extract data incrementally from the Oracle table. Once data is extracted incrementally, it cannot be inserted into the target table directly. There will be new and updated records that have to be treated accordingly. Earlier in this document, we mentioned that Snowflake supports SQL constraints. Adding to that, another surprising feature from Snowflake is support for row-level data manipulations which makes it easier to handle delta data load. The basic idea is to load incrementally extracted data into an intermediate or temporary table and modify records in the final table with data in the intermediate table. The three methods mentioned below are generally used for this. 1. Update the rows in the target table with new data (with the same keys). Then insert new rows from the intermediate or landing table which are not in the final table. UPDATE oracle_target_table t SET t.value = s.value FROM landing_delta_table in WHERE t.id = in.id; INSERT INTO oracle_target_table (id, value) SELECT id, value FROM landing_delta_table WHERE NOT id IN (SELECT id FROM oracle_target_table); 2. Delete rows from the target table which are also in the landing table. Then insert all rows from the landing table to the final table. Now, the final table will have the latest data without duplicates DELETE .oracle_target_table f WHERE f.id IN (SELECT id from landing_table); INSERT oracle_target_table (id, value) SELECT id, value FROM landing_table; 3. MERGE Statement – Standard SQL merge statement which combines Inserts and updates. It is used to apply changes in the landing table to the target table with one SQL statement MERGE into oracle_target_table t1 using landing_delta_table t2 on t1.id = t2.id WHEN matched then update set value = t2.value WHEN not matched then INSERT (id, value) values (t2.id, t2.value); This method of connecting Oracle to Snowflake works when you have a comfortable project timeline and a pool of experienced engineering resources that can build and maintain the pipeline. However, the method mentioned above comes with a lot of coding and maintenance overhead. Limitations of Manual ETL Process Here are some of the challenges of migrating from Oracle to Snowflake. Cost:The cost of hiring an ETL Developer to construct an oracle to Snowflake ETL pipeline might not be favorable in terms of expenses. Method 1 is not a cost-efficient option. Maintenance:Maintenance is very important for the data processing system; hence your ETL codes need to be updated regularly due to the fact that development tools upgrade their dependencies and industry standards change. Also, maintenance consumes precious engineering bandwidth which might be utilized elsewhere. Scalability:Indeed, scalability is paramount! ETL systems can fail over time if conditions for processing fails. For example, what if incoming data increases 10X, can your processes handle such a sudden increase in load? A question like this requires serious thinking while opting for the manual ETL Code approach. Benefits of Replicating Data from Oracle to Snowflake Many business applications are replicating data from Oracle to Snowflake, not only because of the superior scalability but also because of the other advantages that set Snowflake apart from traditional Oracle environments. Many businesses use an Oracle to Snowflake converter to help facilitate this data migration. Some of the benefits of data migration from Oracle to Snowflake include: Snowflake promises high computational power. In case there are many concurrent users running complex queries, the computational power of the Snowflake instance can be changed dynamically. This ensures that there is less waiting time for complex query executions. The agility and elasticity offered by the Snowflake Cloud Data warehouse solution are unmatched. This gives you the liberty to scale only when you needed and pay for what you use. Snowflake is a completely managed service. This means you can get your analytics projects running with minimal engineering resources. Snowflake gives you the liberty to work seamlessly with Semi-structured data. Analyzing this in Oracle is super hard. Conclusion In this article, you have learned about two different approaches to set up Oracle to Snowflake Integration. The manual method involves the use of SQL*Plus and also staging the files to Amazon S3 before copying them into the Snowflake Data Warehouse. This method requires more effort and engineering bandwidth to connect Oracle to Snowflake.
