--------------------------------

             Summary: [Federation] Improve SQLFederationStateStore DataSource Config
                 Key: YARN-11340
                 URL: https://issues.apache.org/jira/browse/YARN-11340
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: federation
    Affects Versions: 3.4.0
            Reporter: fanshilun
            Assignee: fanshilun


SQLFederationStateStore uses HikariCP, which is a very efficient thread pool, but currently only exposes the max-connections parameter, we need more configuration to control the thread pool Added minimum-idle, pool-name, idle-timeout, max-lifetime, connection-timeout parameter configuration to allow users to better use the built-in thread pool.
