Adding an Amazon S3 location to your data lake - AWS Lake Formation

Adding an Amazon S3 location to your data lake

To add an Amazon Simple Storage Service (Amazon S3) location as storage in your data lake, you register the location with AWS Lake Formation. You can then use Lake Formation permissions for fine-grained access control to AWS Glue Data Catalog objects that point to this location, and to the underlying data in the location.

Lake Formation also allows to register a data location in hybrid access mode and provide you the flexibility to selectively enable Lake Formation permissions for databases and tables in your Data Catalog. With the Hybrid access mode, you now have an incremental path that allows you to set Lake Formation permissions for a specific set of users without interrupting the permission policies of other existing users or workloads.

For more information on setting up hybrid access mode, see Hybrid access mode

When you register a location, that Amazon S3 path and all folders under that path are registered.

For example, suppose that you have an Amazon S3 path organization like the following:


If you register S3://mybucket/accounting, the sales folder is also registered and under Lake Formation management.
