Sharing Data Catalog tables and databases across Amazon Accounts

You can share Data Catalog resources (databases and tables) with external Amazon accounts by granting Lake Formation permissions on the resources to the external accounts. Users can then run queries and jobs that join and query tables across multiple accounts. With some restrictions, when you share a Data Catalog resource with another account, principals in that account can operate on that resource as if the resource were in their Data Catalog.

You don't share resources with specific principals in external Amazon accounts—you share the resources with an Amazon account or organization. When you share a resource with an Amazon organization, you're sharing the resource with all accounts at all levels in that organization. The data lake administrator in each external account must then grant permissions on the shared resources to principals in their account.
