                    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.
                    This constraint is in place because more than one cache could be involved in a transaction.
                    This timeout controls the time to wait to acquire a distributed lock.

                    Makes clustered operations fail with NamedCacheNotFoundException if the named cache does not exist on remote nodes.
                    If set to false, operations will succeed but it will be logged on the caller that the operation did not succeed on
                    certain nodes due to the named cache not being available. This behaviour is applicable only to replicated caches.
