Clarification on Unity Catalog Metastore - Metadata and storage

APJESK
New Contributor III

Where does the Unity Catalog metastore metadata actually reside?

  • Is it stored and managed in the Databricks account (control plane)?

  • Or does it get stored in the customer-managed S3 bucket when we create a bucket for Unity Catalog metastore?

I want to clarify whether the S3 bucket we configure is only for managed tables/volumes, while the metastore metadata itself stays with Databricks.
