Configure Trino Resource Group
Trino resource groups enable you to control how queries use cluster resources by defining limits for memory usage, concurrent queries, and queued queries.
You can integrate Trino resource groups with a directory service, such as OpenLDAP or Active Directory, to assign queries to resource groups based on a user's directory group membership.
The configuration follows this flow:
Directory user → Directory group → Trino resource group → Query execution.
Note
Manual configuration: Trino resource group configuration currently requires manual updates to the Trino configuration files. Configuration through Ambari is not supported in this release.
Ambari-based configuration management for Trino resource groups is planned in future release.
