  • Method Details

    • migrationStarted

      void migrationStarted(MigrationState state)
      Called when the migration process starts. A migration process consists of a group of partition replica migrations which are planned together.

      When migration process is completed, migrationFinished(MigrationState) is called.

      Parameters:
      state - Plan of the migration process

    • migrationFinished

      void migrationFinished(MigrationState state)
      Called when the migration process finishes. This event denotes ending of migration process which is started by migrationStarted(MigrationState).

      Not all of the planned migrations have to be completed. Some of them can be skipped because of a newly created migration plan.

      If migration process coordinator member (generally the oldest member in cluster) crashes before migration process ends, then this method may not be called at all.

      Parameters:
      state - Result of the migration process

    • replicaMigrationCompleted

      void replicaMigrationCompleted(ReplicaMigrationEvent event)
      Called when a partition replica migration is completed successfully.
      Parameters:
      event - the event for the partition replica migration

    • replicaMigrationFailed

      void replicaMigrationFailed(ReplicaMigrationEvent event)
      Called when a partition replica migration is failed.
      Parameters:
      event - the event for the partition replica migration
