Class BlackHoleBackendQueueProcessorFactory

java.lang.Object
  org.hibernate.search.backend.impl.blackhole.BlackHoleBackendQueueProcessorFactory

All Implemented Interfaces:

BackendQueueProcessorFactory

public class BlackHoleBackendQueueProcessorFactory
extends java.lang.Object
implements BackendQueueProcessorFactory

This backend does not do anything: the Documents are not sent to any index but are discarded. Useful to identify the bottleneck in indexing performance problems, fully disabling the backend system but still building the Documents needed to update an index (loading data from DB).
