Dataproc Metastore IAM roles

Dataproc Metastore defines several Identity and access management (IAM) roles. Each predefined role contains a set of IAM permissions that allow principals to perform certain actions. You can use an IAM policy to give a principal one or more IAM roles.

Identity and Access Management (IAM) also offers the ability to create customized IAM roles. You can create custom IAM roles and assign the role one or more permissions. Then, you can grant the new role to your principals. Use custom roles to create an access control model that maps directly to your needs, alongside the available predefined roles.

This page focuses on the IAM roles relevant to Dataproc Metastore.

Dataproc Metastore roles

Identity and Access Management (IAM) Dataproc Metastore roles are a bundle of one or more permissions. You grant roles to principals to allow them to perform actions on the Dataproc Metastore resources in your project. For example, the Dataproc Metastore User role contains the metastore.*.get and metastore.*.list permissions, which allow a user to get and list Dataproc Metastore services, metadata imports, backups, and operations in a project.

The following table lists all Dataproc Metastore roles and the permissions associated with each role:

Note: The databases and tables permissions are used with gRPC-enabled Dataproc Metastore services. They have no effect when used with services using Thrift endpoints.
