    Details

    • Sprint:
      HDDS Biscayne

      Description

      In case a follower lags behind the leader by a large number, the leader tries to send the snapshot to the follower. For ContainerStateMachine, the information in the snapshot it not the entire state machine data. InstallSnapshot for ContainerStateMachine should be disabled.
