In December, we shared our vision for completing the lakehouse: open storage, open access, and unified governance. We described a world where organizations could define fine-grained access policies once in Unity Catalog and have them enforced across every engine, on every table, for every user. Today, we’re extending that vision.
We're announcing the Beta of cross-engine ABAC, which enables enterprises to enforce attribute-based access controls (ABAC) on external engines using Iceberg REST Catalog APIs. With cross-engine ABAC, Unity Catalog becomes the first and only catalog to deliver cross-engine ABAC enforcement, allowing tag-based row filters and column masks to be enforced from every engine.
