public class StatelessHibernateSpaceSynchronizationEndpoint
extends AbstractHibernateSpaceSynchronizationEndpoint

A SynchronizationEndpointInterceptor implementation based on Hibernate StatelessSession.

Note, stateless session is much faster than regular Hibernate session, but at the expense of not having a first level cache, as well as not performing any cascading operations (both in read operations as well as dirty operations).

StatelessHibernateSpaceSynchronizationEndpoint

public StatelessHibernateSpaceSynchronizationEndpoint(org.hibernate.SessionFactory sessionFactory,
                                                      Set<String> managedEntries)

Method Detail

onTransactionSynchronization

public void onTransactionSynchronization(TransactionData transactionData)

Perform the given transation changes using Hibernate StatelessSession. First, tries to perform "optimistic" operations without checking in advance for existence of certain entity. If this fails, will try and perform the same operations again, simply with checking if the entry exists or not.

Overrides:

onTransactionSynchronization in class SpaceSynchronizationEndpoint

Parameters:

transactionData - the transaction data

onOperationsBatchSynchronization

public void onOperationsBatchSynchronization(OperationsBatchData batchData)

Perform the given batch changes using Hibernate StatelessSession. First, tries to perform "optimistic" operations without checking in advance for existence of certain entity. If this fails, will try and perform the same operations again, simply with checking if the entry exists or not.

Overrides:

onOperationsBatchSynchronization in class SpaceSynchronizationEndpoint

Parameters:

batchData - the batched operations data
