18.5. Transaction Synchronization

18.5.1. About Transaction (JTA) Synchronizations

JTA synchronizations inform JBoss Data Grid about transaction life cycle events. Registering a synchronization also allows JBoss Data Grid to respond to transactional events without being registered as a XAResource. As a result, the Transaction Manager optimizes transaction operations so that they require the one phase commit (1PC) algorithm instead of the two phase commit (2PC) algorithm.

In JBoss Data Grid, JTA synchronizations are only available in Library mode.
