Ben Wang commented on JBCACHE-702:
----------------------------------

I have decided to use the thread local approach, InvocationContext to provide the region concept. The usage will be:

InvocationContext.setRegion("SESSION");
cache.attach()
cache.detach()
...

> Currently, the design of flat space mapping in 2.0 means that the object graph doesn't reside under the same tree. When we have buddy replication, eviction or cacheloader, this can be a problem to implement. The best solution is to have an notion of region. For example, something toward this line:
> cache.attach(region, id, pojo) 
> will ensure everything is put under /region/id, and __JBOSS_INTERNAL__/region/guid
> I am thinking to put this in an Option class such as:
> cache.attach(id, pojo, option)
> so it is more generic.
