Example 57 with PartitionReplica

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

the class PartitionReplicaManager method triggerPartitionReplicaSync.

/**
 * This method is called on a backup node (replica). Given all conditions are satisfied, this method initiates a replica sync
 * operation and registers it to replicaSyncRequest. The operation is scheduled for a future execution if :
 * <ul>
 * <li>the {@code delayMillis} is greater than 0</li>
 * <li>if a migration is not allowed (during repartitioning or a node joining the cluster)</li>
 * <li>the partition is currently migrating</li>
 * <li>another sync request has already been sent</li>
 * <li>the maximum number of parallel synchronizations has already been reached</li>
 * </ul>
 *
 * @param partitionId  the partition which is being synchronized
 * @param namespaces   namespaces of partition replica fragments
 * @param replicaIndex the index of the replica which is being synchronized
 * @throws IllegalArgumentException if the replica index is not between 0 and {@link InternalPartition#MAX_REPLICA_COUNT}
