Description

Some Iceberg REST catalog implementations like Gravitino provide credential vending features to manage security information centrally and safely. If user has the right privilege to access the table, IRC server will generate a temporary token to access the underlying storage. Please refer to https://gravitino.apache.org/docs/0.8.0-incubating/security/credential-vending for more details about credential vending in Gravitino.

Use case

After supports credential vending, all security information is managed in Iceberg REST server, which means:

1. user doesn't need to specify AKSK when creating catalogs
2. User could use temporary scoped token to access the data without the risk of leaking the AKSK.
