Chapter 10. Enabling APIs Declaratively

Batching allows atomicity and some characteristics of a transaction, but does not allow full-blown JTA or XA capabilities. Batching is typically lighter and cheaper than a full-blown transaction, and should be used whenever the only participant in the transaction is the JBoss Data Grid cluster. If the transaction involves multiple systems then JTA Transactions should be used. For example, consider a transaction which transfers money from one bank account to another. If both accounts are stored within the JBoss Data Grid cluster then batching could be used; however, if only one account is inside the cluster, with the second being in an external database, then distributed transactions are required.

By default invocation batching is disabled; in addition, a transaction manager is not required to use batching.
