What makes a catalog open? Unity Catalog Advances the Open Lakehouse
An open catalog requires storage you own, full features on that storage, and the ability to move tables without copying data. Unity Catalog in Databricks’ Open Lakehouse meets all three by keeping managed tables in customer-owned cloud storage. It supports REGISTER and UNREGISTER from the Apache Iceberg REST catalog spec, enabling tables to enter or leave without data movement. Databricks contributed UNREGISTER to the Iceberg REST catalog spec, making this an open standard. On other platforms, customer-owned storage often lacks features like fail-safe recovery or automatic compaction, pushing users toward provider-controlled storage.

The best engineering reads, once a week.
