Hi @saguiarde.
We do support connections via jdbc to third party databases. Basically, you'll need to follow these instructions:
- Download the jdbc driver from BigQuery
- Copy the driver to <tomcat_home>\lib
- Restart Tomcat
- In Composer, create a Database thing
- In the Configuration tab for the Database thing, enter the details for connecting to your database
We don't test connections to all databases, therefore, if you run into issues, you may want to take the SDK route or post your additional questions here for follow up from other community members that may have some experience with this.
Regards.
