In the current mass indexer, there're 2 parameters for different sizes:
* {{objectLoadingBatchSize}}: Sets the batch size used to load the root entities.
* {{idFetchSize}}: Specifies the fetch size to be used when loading primary keys if objects to be indexed.
In JSR-352, we use a single value ({{fetchSize}}) for both {{idFetchSize}} and {{objectLoadingBatchSize}}. See:
* {{org.hibernate.search.jsr352.massindexing.impl.steps.lucene.PartitionMapper.buildScrollableResults(StatelessSession, Session, Class<?>, Set<Criterion>)}}
* {{org.hibernate.search.jsr352.massindexing.impl.steps.lucene.EntityReader.buildScrollUsingCriteria(StatelessSession, PartitionBound, Object, JobContextData)}}
We may want to split them in the future.
