Synchronize Databricks Unity Catalog

Synchronizing Databricks Unity Catalog is the process of integrating metadata from the databases connected to Databricks Unity Catalog and making the data available in Collibra Data Intelligence Cloud.

You can synchronize manually, or you can automate it by adding a synchronization schedule.

Before you begin

  • You have created a connection to Databricks in your Edge site.
  • You have added the Databricks Unity Catalog capability for the connection.
  • You know in which System asset you want to add the Databricks Unity Catalog assets.
    • If you have registered Databricks databases via the JDBC driver before, use the same System asset.
    • If you never registered Databricks databases before, create a new System asset manually and use that one.
