Example 1 with PartitionMigrationEvent

use of com.hazelcast.internal.partition.PartitionMigrationEvent in project hazelcast by hazelcast.

the class FinalizeMigrationOperation method notifyServices.

/**
 * Notifies all {@link MigrationAwareService}s that the migration finished. The services can then execute the commit or
 * rollback logic. If this node was the source and backup replica for a partition, the services will first be notified that
 * the migration is starting.
 */

    PartitionMigrationEvent event = getPartitionMigrationEvent();
    Collection<MigrationAwareService> migrationAwareServices = getMigrationAwareServices();
    // knows replica is moved away from itself.
    if (isOldBackupReplicaOwner()) {
        // execute beforeMigration on old backup before commit/rollback
