SET TAGorSET TAGSand requiringAPPLY TAG. Governed tags restrict allowed keys, values and assigners across the account. - Unity Catalog
Azure Databricks' governance solution covering both data and AI in one place, with centralised permissions, auditing, data discovery and lineage.
- Governed tags
Tags defined at account level and controlled by a tag policy that sets permitted values and who can apply them. Catalogs and schemas pass them down to child objects (columns do not inherit them), and ABAC policies use them as the attributes to match.
- ASSIGN
