Many businesses generate data and store it in the form of a file. However, the data stored in these files can not be used as it is for analysis. Given data is now the new oil, businesses need a way to move data into a database or data warehouse so that they can leverage the power of a SQL-like language to answer their key questions in a matter of seconds. This article talks about loading the data stored in files on FTP to BigQuery Data Warehouse.
Introduction to FTP
FTP stands for File Transfer Protocol, which is the standard protocol used to transfer files from one machine to another machine over the internet. When downloading an mp3 from the browser or watching movies online, have you encountered a situation where you are provided with an option to download the file from a specific server? This is FTP in action.
FTP is based on a client-server architecture and uses two communication channels to operate:
- A command channel that contains the details of the request
- A data channel that transmits the actual file between the devices
Using FTP, a client can upload, download, delete, rename, move and copy files on a server. For example, businesses like Adobe offer their software downloads via FTP.
Google_BigQuery">Introduction to Google BigQuery
Bigquery is a NoOps (No operations) data warehouse as a service provided by Google to their customers to process over petabytes of data in seconds using SQL as a programming language. BigQuery is a cost-effective, fully managed, serverless, and highly available service.
Since Bigquery is fully managed, it takes the burden of implementation and management off the user, making it super easy for them to focus on deriving insights from their data.
You can read more about the features of BigQuery here.
There are two ways of moving data from FTP Server to BigQuery:
Method 1: Using Custom ETL Scripts to Move Data from FTP to BigQuery
To be able to achieve this, you would need to understand how the interfaces of both FTP and BigQuery work, hand-code custom scripts to extract, transform and load data from FTP to BigQuery. This would need you to deploy tech resources.
Method 2: Using LIKE.TG Data to Move Data from FTP to BigQuery
The same can be achieved using a no-code data integration product like LIKE.TG Data. LIKE.TG is fully managed and can load data in real-time from FTP to BigQuery. This will allow you to stop worrying about data and focus only on deriving insights from it.

Methods to Move Data from FTP to BigQuery
These are the methods you can use to move data from FTP to BigQuery in a seamless fashion:
- Method 1: Using Custom ETL Scripts to Move Data from FTP to BigQuery
- Method 2: Using LIKE.TG Data to Move Data from FTP to BigQuery
Method 1: Using Custom ETL Scripts to Move Data from FTP to BigQuery
The steps involved in loading data from FTP Server to BigQuery using Custom ETL Scripts are as follows:
- Step 1: Connect to BigQuery Compute Engine
- Step 2: Copy Files from Your FTP Server
- Step 3: Load Data into BigQuery using BQ Load Utility
Step 1: Connect to BigQuery Compute Engine
- Download the WINSCP tool for your device.
- Open WinSCP application to connect to the Compute Engine instance.
- In the session, the section select ‘FTP’ as a file protocol.
- Paste external IP in Host Name.
- Use key-comment as a user name. Lastly, click on the login option.
Step 2: Copy Files from Your FTP Server
On successful login, copy the file to VM.
Step 3: Load Data into BigQuery using BQ Load Utility
(In this article we are loading a “.CSV” file)
1. SSH into your compute engine VM instance, go to the directory in which you have copied the file.
2. Execute the below command
bq load --autodetect --source_format=CSV test.mytable testfile.csv
For more bq options please read the bq load CLI command google documentation.
3. Now verify the data load by selecting data from the “test.mytable” table by opening the BigQuery UI.
Thus we have successfully loaded data in the BigQuery table using FTP.
Limitations of Using Custom ETL Scripts to Move Data from FTP to BigQuery
Here are the limitations of using Custom ETL Scripts to move data from FTP to BigQuery:
- The entire process would have to be set up manually. Additionally, once the infrastructure is up, you would need to provide engineering resources to monitor FTP server failure, load failure, and more so that accurate data is available in BigQuery.
- This method works only for a one-time load. If your use case is to do a change data capture, this approach will fail.
- For loading data in UPSERT mode will need to write extra lines of code to achieve this functionality.
- If the file contains any special character or unexpected character data load will fail.
- Currently, bq load supports only a single character delimiter, if we have a requirement of loading multiple characters delimited files, this process will not work.
- Since in this process, we are using multiple applications, so in case of any process, abortion backtracking will become difficult.
