How can I control access to feature tables in a Databricks workspace that is not enabled for Unity Catalog?
To control access to feature tables in a Databricks workspace that is not enabled for Unity Catalog, you can configure Feature Store access control to grant fine-grained permissions on feature table metadata. This allows you to control a user’s ability to view a feature table in the UI, edit its description, manage other users’ permissions on the table, and delete the table.

There are three permission levels you can assign to feature table metadata: CAN VIEW METADATA, CAN EDIT METADATA, and CAN MANAGE. By default, when a feature table is created, the creator has CAN MANAGE permission, workspace admins have CAN MANAGE permission, and other users have NO PERMISSIONS.

To configure permissions for a specific feature table, you can go to the feature table page, click the arrow to the right of the name of the feature table, and select Permissions. From there, you can edit the permissions and click Save.

Workspace administrators can also use the Feature Store UI to set permission levels on all feature tables for specific users or groups. To do this, go to the feature store page and click Permissions. This button is only available for workspace administrators and users with CAN MANAGE permission for the Feature Store. From there, you can edit the permissions and click Save.

Permissions set from the feature store page also apply to all future feature tables. Permissions set on the Feature Store page can only be removed from that page. On the feature table page, you can override settings from the Feature Store page to add permissions, but you cannot set more restrictive permissions.
