Cross-Region data access limitations - AWS Lake Formation

Cross-Region data access limitations

Lake Formation supports querying Data Catalog tables across AWS Regions. You can access data in a Region from other Regions using Amazon Athena, Amazon EMR, and AWS Glue ETL by creating resource links in other Regions pointing to the source databases and tables. With cross-Region table access, you can access data across Regions without copying the underlying data or the metadata into the Data Catalog.

The following limitations apply to cross-Region table access.

  • Lake Formation doesn't support querying Data Catalog tables from another Region using Amazon Redshift Spectrum.

  • In the Lake Formation console, the database and table views don't show the source Region database/table names.

  • To view the list of tables under a shared database from another Region, you need to first create a resource link to the shared database, then select the resource link, and choose View tables.

  • Lake Formation doesn't support cross-Region resource link calls made by SAML users.
