             Summary: Make the thread nums of io executor of ClusterEntrypoint and MiniCluster configurable
                 Key: FLINK-17248
                 URL: https://issues.apache.org/jira/browse/FLINK-17248
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing, Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Yun Tang


FLINK-11851 introduce dedicated io executor for ClusterEntrypoint and MiniCluster with the the thread num as the cpu cores. However, this could introduce extra regression as we might use fewer threads compared with akka service before, e.g.FLINK-17073 . However, we cannot configure the thread num of the io executor to avoid such regression.

One idea is to introduce such configuration to make the thread nums of io executor of ClusterEntrypoint and MiniCluster configurable.
