Method Details

newResponseInstance

protected ReplicationResponse newResponseInstance(StreamInput in)
                                           throws IOException

Specified by:

newResponseInstance in class TransportReplicationAction<ShardFlushRequest,ShardFlushRequest,ReplicationResponse>

Throws:

IOException

shardOperationOnPrimary

protected void shardOperationOnPrimary(ShardFlushRequest shardRequest,
 IndexShard primary,
 ActionListener<TransportReplicationAction.PrimaryResult<ShardFlushRequest,ReplicationResponse>> listener)

Description copied from class: TransportReplicationAction

Primary operation on node with primary copy.

Specified by:

shardOperationOnPrimary in class TransportReplicationAction<ShardFlushRequest,ShardFlushRequest,ReplicationResponse>

Parameters:

shardRequest - the request to the primary shard

primary - the primary shard to perform the operation on

splitRequestOnPrimary

protected Map<ShardId,ShardFlushRequest> splitRequestOnPrimary(ShardFlushRequest request)

Description copied from class: TransportReplicationAction

During Resharding, we might need to split the primary request. We are here because there was mismatch between the SplitShardCountSummary in the request and that on the primary shard node. We assume that the request is exactly 1 reshard split behind the current state.

Overrides:

splitRequestOnPrimary in class TransportReplicationAction<ShardFlushRequest,ShardFlushRequest,ReplicationResponse>

combineSplitResponses

protected Tuple<ReplicationResponse,Exception> combineSplitResponses(ShardFlushRequest originalRequest,
 Map<ShardId,ShardFlushRequest> splitRequests,
 Map<ShardId,Tuple<ReplicationResponse,Exception>> responses)

Overrides:

combineSplitResponses in class TransportReplicationAction<ShardFlushRequest,ShardFlushRequest,ReplicationResponse>

shardOperationOnReplica

protected void shardOperationOnReplica(ShardFlushRequest request,
 IndexShard replica,
 ActionListener<TransportReplicationAction.ReplicaResult> listener)

Description copied from class: TransportReplicationAction

Execute the specified replica operation. This is done under a permit from IndexShard.acquireReplicaOperationPermit(long, long, long, ActionListener, Executor).

Specified by:

shardOperationOnReplica in class TransportReplicationAction<ShardFlushRequest,ShardFlushRequest,ReplicationResponse>

Parameters:

request - the request to the replica shard

replica - the replica shard to perform the operation on
