IngestService

public IngestService(ClusterService clusterService, ThreadPool threadPool, Environment env, ScriptService scriptService, AnalysisRegistry analysisRegistry, java.util.List<IngestPlugin> ingestPlugins, Client client)

Method Details

getClusterService

public ClusterService getClusterService()

getScriptService

public ScriptService getScriptService()

delete

public void delete(DeletePipelineRequest request, ActionListener<AcknowledgedResponse> listener)

Deletes the pipeline specified by id in the request.

getPipelines

public static java.util.List<PipelineConfiguration> getPipelines(ClusterState clusterState, java.lang.String... ids)

Returns:

pipeline configuration specified by id. If multiple ids or wildcards are specified multiple pipelines may be returned

putPipeline

public void putPipeline(java.util.Map<DiscoveryNode,IngestInfo> ingestInfos, PutPipelineRequest request, ActionListener<AcknowledgedResponse> listener) throws java.lang.Exception

Stores the specified pipeline definition in the request.

Throws:

java.lang.Exception

getPipeline

public Pipeline getPipeline(java.lang.String id)

Returns the pipeline by the specified id

getProcessorFactories

public java.util.Map<java.lang.String,Processor.Factory> getProcessorFactories()

info

public IngestInfo info()

innerPut

public static ClusterState innerPut(PutPipelineRequest request, ClusterState currentState)

executeBulkRequest

public void executeBulkRequest(int numberOfActionRequests, java.lang.Iterable<DocWriteRequest<?>> actionRequests, java.util.function.BiConsumer<java.lang.Integer,java.lang.Exception> onFailure, java.util.function.BiConsumer<java.lang.Thread,java.lang.Exception> onCompletion, java.util.function.IntConsumer onDropped)

stats

public IngestStats stats()

addIngestClusterStateListener

public void addIngestClusterStateListener(java.util.function.Consumer<ClusterState> listener)

Adds a listener that gets invoked with the current cluster state before processor factories get invoked. This is useful for components that are used by ingest processors, so that they have the opportunity to update before these components get used by the ingest processor factory.

applyClusterState

public void applyClusterState(ClusterChangedEvent event)

Description copied from interface: ClusterStateApplier

Called when a new cluster state (ClusterChangedEvent.state() needs to be applied. The cluster state to be applied is already committed when this method is called, so an applier must therefore be prepared to deal with any state it receives without throwing an exception. Throwing an exception from an applier is very bad because it will stop the application of this state before it has reached all the other appliers, and will likely result in another attempt to apply the same (or very similar) cluster state which might continue until this node is removed from the cluster.

Specified by:

applyClusterState in interface ClusterStateApplier

getProcessorsInPipeline

public <P extends Processor> java.util.List<P> getProcessorsInPipeline(java.lang.String pipelineId, java.lang.Class<P> clazz)

Gets all the Processors of the given type from within a Pipeline.

Parameters:

pipelineId - the pipeline to inspect

clazz - the Processor class to look for

Returns:

True if the pipeline contains an instance of the Processor class passed in
