    • Method Detail

      • execute

        void execute​(boolean success)
        Ideally, this method is called after the load/drop opertion is successfully done, i.e., the historical node removes the zookeeper node from loadQueue and announces/unannouces the segment. However, this method will also be called in failure scenarios so for implementations of LoadPeonCallback that care about success it is important to take extra measures to ensure that whatever side effects they expect to happen upon success have happened. Coordinator will have a complete and correct view of the cluster in the next run period.
