| AttributeBasedClusteredSession | | class AttributeBasedClusteredSession extends JBossCacheClusteredSession (Code) | | Implementation of a clustered session for the JBossCacheManager. The replication granularity
level is attribute based; that is, we replicate only the dirty attributes.
We use JBossCache for our internal, deplicated data store.
The internal structure is like in JBossCache:
/JSESSION
/hostname
/web_app_path (path + session id is unique)
/id Map(id, session)
(VERSION_KEY, version) // Used for version tracking. version is an Integer.
/ATTRIBUTE Map(attr_key, value)
Note that the isolation level of the cache dictates the
concurrency behavior. Also note that session and its associated attribtues are stored in different nodes.
This will be ok since cache will take care of concurrency. When replicating, we will need to replicate both
session and its attributes.
