Databricks recommends that you assign managed storage at the catalog level for logical data isolation, with metastore-level and schema-level as options. New workspaces that are enabled for Unity Catalog automatically are created without a metastore-level managed storage location.
It means that it's a must to create a managed location for a catalog for otpimal data isolations, otherwise you'll finish up with many schemas/tables data in the same managed location which is a bad prctice from governance perspective.
Working with not isolated catalog in Unity Catalog is chaotic, i would prefer to be on my workspace rather than working in such bad governed Unity Catalog.
Ans : ["A", "E"]
The correct answers are A. You can have more than 1 metastore within a Databricks account console but only 1 per region and E. If metastore is not associated with location, it’s mandatory to associate catalog with managed locations. These conditions are applicable for governance in Databricks Unity Catalog
A. You can have more than 1 metastore within a Databricks account console but only 1 per region.
Unity Catalog allows multiple metastores within a Databricks account console. However, each region can only have one active metastore due to geographic restrictions and for managing data governance in a region-specific manner.
E. If metastore is not associated with location, it’s mandatory to associate catalog with managed locations.
When a metastore does not have a default storage location, you must configure managed locations for each catalog to ensure governance and compliance. Managed locations define where Unity Catalog manages and stores data.
Correct - A and D.
A.Unity Catalog allows you to have multiple metastores within a single Databricks account, but each metastore is limited to a single region for data locality and compliance purposes.
D. When a catalog does not have an associated managed location, it becomes necessary to associate schemas within the catalog with managed locations, ensuring that data is stored in a defined path.
