    • notExecuted

      default void notExecuted(Store store, String reason)
      Called if the compaction request is failed for some reason.

    • beforeExecution

      default void beforeExecution(Store store)
      Called before compaction is executed by CompactSplitThread.

      Requesting compaction on a region can lead to multiple compactions on different stores, so we will pass the Store in to tell you the store we operate on.

    • afterExecution

      default void afterExecution(Store store)
      Called after compaction is executed by CompactSplitThread.

      Requesting compaction on a region can lead to multiple compactions on different stores, so we will pass the Store in to tell you the store we operate on.

    • completed

      default void completed()
      Called after all the requested compactions are completed.

      The compaction scheduling is per Store so if you request a compaction on a region it may lead to multiple compactions.
