[jboss-jira] [JBoss JIRA] Created: (JBMESSAGING-1340) In memory session replication

In memory session replication ----------------------------- Key: JBMESSAGING-1340 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1340 Project: JBoss Messaging Issue Type: Task Reporter: Tim Fox Assigned To: Tim Fox Priority: Critical Fix For: 2.0.0 Beta Implement in memory replication of sessions. It will be possible to replicate sessions to a backup node. The replication needs to happen in memory sychronously. Write to journal on both nodes can be lazy (asynchronous) since on failover we can be sure it is in memory on backup so no single point of failover. But can persist to disk asynchronously?? I think we can persist to disk asynchrnously on the master node, but needs to be synchronous on the backup node, in case we get a failure of the backup too shortly after failure of the master. If we can tolerate duplicate messages (or messages thought sent but not store) in a double failure then can do asynchronous storage on both master and slave. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
