[jboss-user] [JBossCache] - Re: PojoCache 2.0: New tree structure, optimistic locking &

[ben.wang@jboss.com]

Hmmn... You are right this is problematic. Each time when a pojo is attached, a new cache node will be created under __JBossInternal__. So for optimistic locking this will be problem for concurrent transaction. This will evitably create high rate of rollback and degrade the performance.

I ahve created a jira:
http://jira.jboss.com/jira/browse/JBCACHE-915

A partial workaround is to use "region" in cache such that __JBossInternal__ is separate for each region. However, for concurrent access under the same region, the problem would still exist.

Any reason that you must use optimistic locking?
