    Description

      JobModelManager uses CoordinatorStreamStore.put() to save job model information which does flush for each message.

      The flush operation in CoordinatorStreamStore is very heavy, so it may take over a very long time for AM to save the information in a run.

      We should use CoordinatorStreamStore's batch put instead of single put.
