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.
