File Group Provider

Enable user-group mapping using the file-based group provider.

Usage

Provision the module:

minitrino provision -m file-group-provider

Connect to the coordinator container’s Trino CLI as the admin user:

minitrino exec -i 'trino-cli --user admin'

Display the groups for the current user via current_groups():

SELECT current_groups();
-- [clusteradmins]

View the groups for the test user:

minitrino exec -i 'trino-cli --user test'

SELECT current_groups();
-- [clusteradmins, metadata-users, platform-users]

Group Mapping

Group	Users
clusteradmins	admin, cachesvc, test
metadata-users	metadata-user, bob, test
platform-users	platform-user, alice, test
