Appendix E. Infinispan Configuration

Minimally, the cache used by a repository needs to be transactional , since the hierarchical database internally uses transactions and works with client-initiated or container-managed JTA transactions.

Applications that may be concurrently updating the same nodes should use Infinispan configured to use pessimistic locking . By default Infinispan will use optimistic locking; this is more efficient for applications that do not update the same nodes, but concurrently updating the same nodes with optimistic locking may very well cause some updates to be lost. If you're not sure, use pessimistic locking.
