Interoperability Between Unity Catalog and Google BigQuery via Catalog Federation

Databricks has implemented catalog federation capabilities that enable Unity Catalog to interoperate with Google BigQuery, allowing users to access and manage BigQuery datasets through the Unity Catalog interface. This integration facilitates seamless data discovery, governance, and access control across both platforms without requiring data migration. The federation approach enables organizations to maintain their existing BigQuery investments while leveraging Databricks' unified metadata and governance layer.
