How to Connect to Google BigQuery using SSIS

Big data processing is essential, but managing it shouldn't be overcomplicated. Google BigQuery excels at handling massive datasets in the cloud, while SSIS is a go-to option for ETL workflows. However, connecting these two platforms can be challenging. That's where Devart SSIS Components for BigQuery step in.

Designed specifically for BigQuery data access, these components transform integration workflows into efficient and effortless operations, addressing the most common pain points for developers, engineers, DBAs, and other data professionals.

Create data flow tasks for BigQuery

Before we commence working with SSIS and BigQuery using Devart SSIS Data Flow Components, make sure the following prerequisites are in place:

SQL Server Data Tools (SSDT) for Visual Studio and SSIS for Visual Studio must be installed
The Devart SSIS Data Flow Components for BigQuery must be installed
The system must match the compatibility requirements

Setting up the Data Flow Task for BigQuery is straightforward:

1. Launch Visual Studio, open the necessary SSIS project and navigate to the Control Flow tab.
2. Right-click and select New Data Flow Task. Rename it, for instance, to BigQuery Data Import.
3. Double-click the task to access the Data Flow tab.

Configure a SSIS BigQuery connection

To connect SSIS to BigQuery with Devart SSIS Components, do the following:

Right-click the Connection Managers panel and select New Connection. Choose Google BigQuery from the available connection types.

Configure the following settings in the Connection Manager Editor:

Refresh Token - the OAuth token for authentication
Project ID - the Google Cloud Project identifier
Dataset ID - the BigQuery dataset name

Click Test Connection to verify the details.

Note

Always double-check your Project ID and DataSet ID permissions to avoid connection issues later.

Select BigQuery data for retrieving using SSIS

First, you need to add a Source Component to the Data Flow Task.

In the Devart BigQuery Source Editor, select the BigQuery connection you configured.

Select the configured Devart data source connection

You will see the list of available tables to choose from on the left. Choose the table and specify the SQL query to retrieve the data from the table.

You don't need to construct the SELECT query manually, simply drag and drop the desired table into the Query field, and the query will be generated automatically. After that, you can preview the data.

You can write and use custom queries for more targeted and precise results. The Source Editor provides the necessary functionality that allows you to write and execute complex SQL queries against the BigQuery data source. Additionally, you can save queries as templates to reuse in future for similar tasks.

Essential SSIS ETL tasks for BigQuery integration

With Devart SSIS Components, you can perform a wide range of ETL tasks, such as:

Data import/export - you can easily transfer data to and from BigQuery in various formats like CSV, XML, and Excel
Data aggregation - aggregate data using sums, averages, or counts for reporting and analysis
Splitting and merging data - split large datasets into smaller parts or merge multiple datasets for unified processing
Cloud integration - integrate BigQuery data with cloud platforms like Amazon S3, Google Cloud Storage, and Azure Blob
Data replication - automate the replication of BigQuery data for backing up or synchronized reporting
Backup and migration - schedule routine backups or migrate data between platforms
