org.hibernate.search.batchindexing
Class IdentifierProducer

java.lang.Object
  org.hibernate.search.batchindexing.IdentifierProducer

All Implemented Interfaces:

java.lang.Runnable

public class IdentifierProducer
extends java.lang.Object
implements java.lang.Runnable

This Runnable is going to feed the indexing queue with the identifiers of all the entities going to be indexed. This step in the indexing process is not parallel (should be done by one thread per type) so that a single transaction is used to define the group of entities to be indexed. Produced identifiers are put in the destination queue grouped in List instances: the reason for this is to load them in batches in the next step and reduce contention on the queue.

IdentifierProducer

public IdentifierProducer(ProducerConsumerQueue<java.util.List<java.io.Serializable>> fromIdentifierListToEntities,
                          org.hibernate.SessionFactory sessionFactory,
                          int objectLoadingBatchSize,
                          java.lang.Class<?> indexedType,
                          MassIndexerProgressMonitor monitor,
                          long objectsLimit)

Parameters:

fromIdentifierListToEntities - the target queue where the produced identifiers are sent to

sessionFactory - the Hibernate SessionFactory to use to load entities

objectLoadingBatchSize - affects mostly the next consumer: IdentifierConsumerEntityProducer

indexedType - the entity type to be loaded

monitor - to monitor indexing progress

objectsLimit - if not zero
