[jboss-jira] [JBoss JIRA] Resolved: (JBCACHE-957) Allow per-node configuration of LockParentForChildInsertRemove

Allow per-node configuration of LockParentForChildInsertRemove -------------------------------------------------------------- Key: JBCACHE-957 URL: http://jira.jboss.com/jira/browse/JBCACHE-957 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 2.0.0.GA, 1.4.1.SP1 Reporter: Brian Stansberry Assigned To: Manik Surtani Fix For: 2.1.0.GA Attachments: lock.diff Use the new LockParentForChildInsertRemove as a global default that sets a per-node behavior. Expose an API in Node (not NodeSPI) that allows the application to change the behavior for an individual node. Use case: session replication, which stores data in a structure like this: /SESSION/webapp/session1/.../... /SESSION/webapp/session2/.../... The session managment layer wants the greater correctness that comes with enforcing LockParentForChildInsertRemove="true" with the sessionX node and below. But requiring a WL on /SESSION/webapp before any session could be added or removed will greatly disrupt session creation and expiration. This feature allows the best of both worlds, by allowing the application to set LockParentForChildInsertRemove="false" on /SESSION and /SESSION/webapp. This is a simple alternative to lock striping in the node's children map.
