[jboss-jira] [JBoss JIRA] Reopened: (JBCACHE-961) Optimistic locking to support more sophisticated merging of child maps

Optimistic locking to support more sophisticated merging of child maps ---------------------------------------------------------------------- Key: JBCACHE-961 URL: http://jira.jboss.com/jira/browse/JBCACHE-961 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 1.4.1.GA Reporter: Manik Surtani Assigned To: Manik Surtani Fix For: 2.0.0.GA, 2.0.0.BETA2, 1.4.1.SP3 At the moment at commit time parent nodes in a workspace have their child maps used to overwrite the underlying data nodes. As such, version increments are necessary on the parents, very bad for concurrency. A more sophisticated merging mechanism is needed here, perhaps along the lines of: 1) Children added placed in an addedChildren map 2) Children removed placed in a childrenRemoved map at commit time, use these 2 maps to look at what exists in the underlying node and merge in accordingly. Related to JBCACHE-955 and JBCACHE-956.
