Granting resource link permissions - AWS Lake Formation

Granting resource link permissions

Follow these steps to grant AWS Lake Formation permissions on one or more resource links to a principal in your AWS account.

After you create a resource link, only you can view and access it. (This assumes that Use only IAM access control for new tables in this database is not enabled for the database.) To permit other principals in your account to access the resource link, grant at least the DESCRIBE permission.

Important

Granting permissions on a resource link doesn't grant permissions on the target (linked) database or table. You must grant permissions on the target separately.

You can grant permissions by using the Lake Formation console, the API, or the AWS Command Line Interface (AWS CLI).
