[jira] [Created] (AMQ-7316) Network connector is not able to handle bunch of destinations

Jean-Baptiste Onofré created AMQ-7316:
-----------------------------------------

             Summary: Network connector is not able to handle bunch of destinations
                 Key: AMQ-7316
                 URL: https://issues.apache.org/jira/browse/AMQ-7316
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker, networkbridge
    Affects Versions: 5.15.10, 5.15.9, 5.11.1
            Reporter: Jean-Baptiste Onofré
            Assignee: Jean-Baptiste Onofré


In a setup where we have a lot of destinations (let say ~ 1000 queues) on a dynamic network connector, we are loosing/delay the advisory messages (for instance when a client consumes from a queue).
That's cause issue on the network bridge and we can see (on JMX or wenconsole) that we can have "stale" active bridge consumer on a queue whereas the bridge remote broker don't have any consumer.
We have to improve the number of destinations managed on bridges.

There are four workarounds for this issue:
1. reduce the number of destinations. Obviously, if we have less destination count (topics or queues), there's no bottleneck on the advisory messages.
2. use {{decreaseNetworkPriority}} to limit the number of advisory and prefer local consumers.
3. use a static network of brokers instead of dynamic
4. create several network connectors, each one dealing with subset of queues (using {{dynamicallyIncludedDestinations}}).
