[jboss-user] [JBossCache] - Re: Questions regarding performance of read-only operations

[bstansberry@jboss.com]

All cache operations move through an interceptor stack that handles aspects like locking, transaction management, and interactions with cache loaders.  Replication is just one of those aspects; if the cache is in LOCAL mode the other aspects still have to be properly handled.

An interceptor-based architecture involves an object that carries the invocation through the interceptor stack.  In JBoss Cache this object is a MethodCall.  Use of that particular class, with its roots in JGroups, is largely a result of JBoss Cache's historical roots.  Using that class is a bit conceptually messy, but if we switched to some other class, it would have to perform the same functions MethodCall does.
