Class JGroupsBackendQueueProcessor

java.lang.Object

org.hibernate.search.backend.jgroups.impl.JGroupsBackendQueueProcessor

All Implemented Interfaces:

BackendQueueProcessor

public class JGroupsBackendQueueProcessor
extends Object
implements BackendQueueProcessor

This index backend is able to switch dynamically between a standard Lucene index writing backend and one which sends work remotely over a JGroups channel.

Constructor Detail

JGroupsBackendQueueProcessor

public JGroupsBackendQueueProcessor(NodeSelectorStrategy selectionStrategy,
                                    JGroupsBackendQueueTask jgroupsProcessor,
                                    Supplier<BackendQueueProcessor> delegatedBackendFactory)

Method Detail

close

public void close()

Description copied from interface: BackendQueueProcessor

Used to shutdown and eventually release resources. No other method should be used after this one.

Specified by:

close in interface BackendQueueProcessor

applyWork

public void applyWork(List<LuceneWork> workList,
                      IndexingMonitor monitor)

Description copied from interface: BackendQueueProcessor

Applies a list of operations to the index. A single list might be processed by applying elements in parallel threads, but no work should be started on a new workList until the previous one was fully processed. Work could be applied asynchronously according to capabilities and configuration of implementor. A null parameter is not acceptable, implementations should throw an IllegalArgumentException.

Specified by:

applyWork in interface BackendQueueProcessor

Parameters:

workList - list of Lucene work instance which need to be applied to the index

monitor - a IndexingMonitor object.

applyStreamWork

public void applyStreamWork(LuceneWork singleOperation,
                            IndexingMonitor monitor)

Description copied from interface: BackendQueueProcessor

Applies a single operation on the index, and different operations can be applied in parallel, even in parallel to a workList instance being processed by BackendQueueProcessor.applyWork(List, IndexingMonitor)

Specified by:

applyStreamWork in interface BackendQueueProcessor

Parameters:

singleOperation - single Lucene work instance to be applied to the index

monitor - a IndexingMonitor object.

blocksForACK

public boolean blocksForACK()

getExistingDelegate

public BackendQueueProcessor getExistingDelegate()

getMessageTimeout

public long getMessageTimeout()
