@MBean(objectName="Invalidation",
       description="Component responsible for invalidating entries on remote caches when entries are written to locally.")
public class InvalidationInterceptor
extends BaseRpcInterceptor
implements JmxStatisticsExposer

This interceptor acts as a replacement to the replication interceptor when the CacheImpl is configured with ClusteredSyncMode as INVALIDATE.

The idea is that rather than replicating changes to all caches in a cluster when write methods are called, simply broadcast an InvalidateCommand on the remote caches containing all keys modified. This allows the remote cache to look up the value in a shared cache loader which would have been updated with the changes.

Transactional caches, still lock affected keys on the primary owner:

• Pessimistic caches acquire locks with an explicit lock command and release during the one-phase PrepareCommand.
• Optimistic caches acquire locks during the 2-phase prepare command and release locks with a TxCompletionNotificationCommand.
