B.2. About Consistency Guarantee

Despite the locking of a single owner instead of all owners, JBoss Data Grid's consistency guarantee remains intact. The consistency guarantee is as follows:

If Key K is hashed to nodes {A,B} and transaction TX1 acquires a lock for K on, for example, node A.
If another cache access occurs on node B, or any other node, and TX2 attempts to lock K, it fails with a timeout because the transaction TX1 already holds a lock on K.

This lock acquisition attempt always fails because the lock for key K is always deterministically acquired on the same node of the cluster, irrespective of the transaction's origin.
