You are rolling out Unity Catalog across multiple workspaces on AWS. Teams need centralized governance for external data in S3 and want cluster isolation aligned with Unity Catalog. What is the correct baseline configuration?
💡 Model Answer
The baseline is to create storage credentials and external locations, register the S3 data in Unity Catalog, and run clusters in either Shared or Single‑User access mode. First, create a storage credential that points to the S3 bucket and attach it to an external location in UC. Register the external location as a table or view in the catalog. Then, configure each workspace’s clusters to use the UC‑managed storage credential and enable cluster isolation by selecting Shared or Single‑User mode. This setup gives you fine‑grained ACLs on the catalog objects, ensures that each cluster can only access the data it is authorized to, and keeps governance centralized in UC while still allowing teams to work in isolated compute environments.
