Create the concept of a "priority queue" to speed execution of certain remote method invocations ------------------------------------------------------------------------------------------------ Key: JBCACHE-326 URL: http://jira.jboss.com/jira/browse/JBCACHE-326 Project: JBoss Cache Issue Type: Task Security Level: Public(Everyone can see) Reporter: Brian Stansberry Assigned To: Vladimir Blagojevic Fix For: 2.1.0.GA Change the handling of requests in JBossCache (another interceptor on top of ReplicationInterceptor): - Create 2 queues (of MethodCall objects), one thread for each queue - The regular MethodCalls like put(), remove() etc go into the default queue (A), where they are processed according to order (FIFO) - The special calls like block(), _getState(), commit() or acks for PREPARE/COMMIT calls go into the other (priority) queue (B), these calls *CAN* be received out of sequence - This way, an _getState() would always be processed and would be able to (1) stop the processing of queue A and (2) force- release any locks held by on the tree. _ This way commit() calls can promptly release locks, without having to wait behind other prepare calls.
