DATAGRID_SPLIT

Allow multiple instances of JBoss Data Grid server to share the same persistent volume.

TRANSPORT_LOCK_TIMEOUT

Infinispan uses a distributed lock to maintain a coherent transaction log during state transfer or rehashing, which means that only one cache can be doing state transfer or rehashing at the same time.
