shards
protected ShardsIterator shards(ClusterState clusterState, IndicesStatsRequest request, String[] concreteIndices) Status goes across *all* shards.- Specified by:
shardsin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
clusterState- the cluster staterequest- the underlying requestconcreteIndices- the concrete indices on which to execute the operation- Returns:
- the shards on which to execute the operation
-
checkGlobalBlock
Description copied from class:TransportBroadcastByNodeActionExecutes a global block check before polling the cluster state.- Specified by:
checkGlobalBlockin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
state- the cluster staterequest- the underlying request- Returns:
- a non-null exception if the operation is blocked
-
checkRequestBlock
protected ClusterBlockException checkRequestBlock(ClusterState state, IndicesStatsRequest request, String[] concreteIndices) Description copied from class:TransportBroadcastByNodeActionExecutes a global request-level check before polling the cluster state.- Specified by:
checkRequestBlockin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
state- the cluster staterequest- the underlying requestconcreteIndices- the concrete indices on which to execute the operation- Returns:
- a non-null exception if the operation if blocked
-
readShardResult
Description copied from class:TransportBroadcastByNodeActionDeserialize a shard-level result from an input stream- Specified by:
readShardResultin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
in- input stream- Returns:
- a deserialized shard-level result
- Throws:
IOException
-
getResponseFactory
protected TransportBroadcastByNodeAction.ResponseFactory<IndicesStatsResponse,ShardStats> getResponseFactory(IndicesStatsRequest request, ClusterState clusterState) Description copied from class:TransportBroadcastByNodeActionCreate a response factory based on the requst and the cluster state captured at the time the request was handled. Implementations must avoid capturing the full cluster state if possible.- Specified by:
getResponseFactoryin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats>
-
readRequestFrom
Description copied from class:TransportBroadcastByNodeActionDeserialize a request from an input stream- Specified by:
readRequestFromin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
in- input stream- Returns:
- a de-serialized request
- Throws:
IOException
-
shardOperation
protected void shardOperation(IndicesStatsRequest request, ShardRouting shardRouting, Task task, ActionListener<ShardStats> listener) Description copied from class:TransportBroadcastByNodeActionExecutes the shard-level operation. This method is called once per shard serially on the receiving node. This method should not throw an exception, but pass the exception to the listener instead.- Specified by:
shardOperationin classTransportBroadcastByNodeAction<IndicesStatsRequest,IndicesStatsResponse, ShardStats> - Parameters:
request- the node-level requestshardRouting- the shard on which to execute the operationtask- the task for this node-level requestlistener- the listener to notify with the result of the shard-level operation
