Sharing foreign schemas and tables with OpenSharing
GALets providers share foreign schemas and tables federated through Lakehouse Federation from sources such as PostgreSQL and MySQL, without copying the data into Databricks. Sharing them materializes data on the provider's side, which incurs compute and storage costs. Foreign Iceberg tables from external Iceberg catalogs followed (Public Preview 2026-04-09, generally available 2026-09-11), then foreign Delta tables registered in OneLake, a Hive metastore or AWS Glue (Public Preview 2026-08-27, generally available 2026-09-15).
