[jboss-user] [JBossCache] - TreeCache with INVALIDATION_SYNC mode and DB sync issue.

Hi I am using TreeCach with INVALIDATION_SYNC mode. I cache large object graphs so I just want just to notify all cluster nodes when an entry is modified and make rest of the nodes fetch a fresh copy from DB. Lets say I have 2 nodes cluster with node#1 and node#2. A cached object is modified on node#1, it sends notification to the other node and update the records on DB.Now the load balancer ask node#2 to do something with this object, so it tries to fetch from cache, see its not there and goes to DB to get a fresh copy. My concern is: What if node#1 did not commit the update yet? node#2 will get an old copy... How can I make sure that I will fetch a "fresh" copy from DB? Using the pojo cache will bypass this problem but I am limited with memory so I am afraid I cant use it.
