Metastore Setup - Databricks Unity Catalog
Metastore
A Unity Metastore in Yeedu links your Databricks Unity Catalog to external object storage (S3, ADLS, GCS) and controls metadata storage and access.
A Unity Metastore configuration includes:
- Unity Metastore URL
- Databricks Personal Access Token
- Default Catalog
- Storage Type
- External Storage Path (e.g., Amazon S3)
- Storage Secret (credentials for your object store)

Scope Levels for Secrets
We apply our usual scope system to the secrets used in a Unity metastore (Databricks PAT & Storage Secret):
| Scope | Visibility |
|---|---|
| User | Only the creator can read/use |
| Workspace | All users in one workspace |
| Tenant | Visible to all users within the tenant |
Creating a Metastore
Click + Metastore at the top right of the Metastore page.
