Introducing Cross-Engine ABAC

Summary

Unity Catalog now enforces attribute-based access controls (ABAC) on external engines, allowing you to define tag-based row filters and column masks once for enforcement from any engine. This centralized governance at the catalog layer, built on Iceberg REST Catalog scan APIs, ensures policies are enforced before data reaches the engine.
