December 14, 2020


The public Preview release of Dataproc Metastore is now available.

Legacy Dataproc Metastore services created during private Preview (prior to December 14, 2020 at 12:00 PM Pacific Standard Time) will be automatically deleted on January 29, 2021.

The Thrift endpoints of legacy services will continue to function normally, but certain pre-existing functionality such as metadata imports will cease to work. Furthermore, new features (including those announced on December 14, 2020) and bugfixes will not be available to legacy services.

To ensure you receive the newest features, patches, and stability, we strongly recommend you recreate legacy Dataproc Metastore services. Since the new metadata export feature is not available for legacy services, if you need help migrating metadata from a legacy service, the Dataproc Metastore team will be happy to assist you with a manual migration.

Please contact with any questions or to request help migrating metadata.
