Class IndexingReducer

java.lang.Object

org.infinispan.query.impl.massindex.IndexingReducer

All Implemented Interfaces:

Serializable, Reducer<Object,org.hibernate.search.backend.LuceneWork>

public final class IndexingReducer
extends Object
implements Reducer<Object,org.hibernate.search.backend.LuceneWork>

This Reduce doesn't really index the entries but forwards them to the appropriate index master; the backend knows how to deal with sharding and this way we avoid unnecessary round trips.
