⚠️ The DataGalaxy Google BigTable will be removed from the list of supported connectors end of June 2026. It won't be available in your platform anymore.
If you're already using the Google BigTable connector plugin of the Desktop connector, you can continue using it at your own risk. But it will not be updated anymore (including regarding vulnerabilities) and the support team won't be able to help you if you encounter issues.
If you want a secure solution for gathering metadata from Google BigTable, use the advanced JDBC mode of the Desktop connector with the Google BigTable JDBC driver.
This article describes how DataGalaxy Google BigTable connector works.
This connector is available in the following modes:
