Subject [jira] [Created] (AMQ-5290) MQTT clients using durable subscriptions on networked brokers received duplicates
Date Fri, 25 Jul 2014 18:49:39 GMT
Timothy Bish created AMQ-5290:
---------------------------------

             Summary: MQTT clients using durable subscriptions on networked brokers received
duplicates
                 Key: AMQ-5290
                 URL: https://issues.apache.org/jira/browse/AMQ-5290
             Project: ActiveMQ
          Issue Type: Improvement
          Components: MQTT
    Affects Versions: 5.10.0
            Reporter: Timothy Bish
             Fix For: 5.11.0


MQTT clients that create durable subscriptions and that operate in a network of Brokers can
receive duplicate messages when they start failing back and forth between brokers in the network.

We should investigate using Virtual Destinations under the covers instead of durable topics
subscriptions as this is a known problem with the durable topic case.  With Virtual Destinations
the client would be subscribed to a Queue that would receive all messages sent to the target
Topic.
