Category: JBossMQ Group: v3.0 Rabbit Hole Status: Open Priority: 5 Submitted By: Sam Goody (sam123us) Assigned to: Nobody/Anonymous (nobody) Summary: FR: Persist selctor expr for durable sub Initial Comment: In current implementation, messages are delivered to a subscriber's store regardless of the selector expression. When the durable subscriber connects to the topic with the selector expression, the messages that match the selector criteria are delivered and others are discarded. This is the desired behavior. But in some scenarios, a durable subscriber may be interested in only a subset of many messages published. The subscriber is going to use the same expression all of the times when connecting to the topic. Also, the subscriber may not be active all the time and would only want only messages that match the selector criteria be retained. In the above secnario, current implementation will queue up many unnecessary messages for a subscriber that eventually may be discarded. It would be best to store the last selector expression used by a durable subscription and use it to determine if a message should be queued or not. I'm not sure if all applications will want this behavior so it is best for it to be configurable on a per subscription basis. Since there might be no standard JMS API to accomplish this, it can be made configurable at a more coarser level such as on a topic level or connection factory level. ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=376688&aid=552984&group_id=22866 _______________________________________________________________ Have big pipes?
