Note that ownership of these keys might change over time so that key ownerships can be almost evenly distributed in the cluster.

MultiMapThe added listener will be only listening for the events (add/remove/update) of the locally owned entries.
Note that entries in distributed multimap are partitioned across the cluster members; each member owns and manages some portion of the entries. Owned entries are called local entries. This listener will be listening for the events of local entries.
For example your cluster has member1 and member2. On member2 you added a
local listener, and from member1, you call multimap.put(key2, value2).
If the key2 is owned by member2, then the local listener will be notified
for the add/update event. Also note that entries can migrate to other
nodes for load balancing and/or membership change.

MultiMapIf the lock is not available, then the current thread becomes disabled for thread scheduling purposes and lies dormant until the lock has been acquired.
The scope of the lock is for this multimap only. The acquired lock is only for the key in this multimap.
Locks are re-entrant, so if the key is locked N times, then it should be unlocked N times before another thread can acquire it.

the binary form of the key, not the actual implementations of
hashCode and equals defined in the key's class.
public void lock(K key, long leaseTime, TimeUnit timeUnit)
MultiMapAfter the lease time, the lock will be released.
