             Summary: Cannot unsubscribe from virtual topics
                 Key: AMQ-4565
                 URL: https://issues.apache.org/jira/browse/AMQ-4565
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 5.8.0
            Reporter: Christian Posta


Virtual Topics allow us to do things with pub/sub that we cannot otherwise do 
with JMS 1.1 spec. However, with durable subs we can "unsubscribe" a consumer 
telling the broker we are no longer interested in messages. If we just stop 
consuming, the queues can fill up.

With the queue-based impl of VT, we have to wait for the queue to be empty to 
delete it... to do that reliably, the producer would have to stop producing? 
And/or we have to use some TTL for the messages? Not sure...
