@iliya-gr I will have to think some more about this.. as we should not route
messages to internal queues on the target as well.
I think we should also add a note discouraging clustering message
distribution with mirror though.
I will have to think over the weekend... I"m pretty sure the target should
route without any internal queues.. otherwise the acks will not send them back
to the mirror where they came from.

> When testing
> [Mirroring|https://activemq.apache.org/components/artemis/documentation/latest/amqp-broker-connections.html#mirroring],
> I found that it works unstable for brokers that are in a cluster. Messages
> are not deleted in the mirror broker if they were distributed ([_*initial
> distribution*_ and
> *_redistribution_*|https://activemq.apache.org/components/artemis/documentation/latest/clusters.html]
> too) from the main to another broker in the cluster.
> I have the following scheme, brokers A1 and A2 into clusters and A1 has
> mirror B1.
> *Steps*
> # Create 3 brokers (A1, A2, B1) with default user (root) and password (root)
> by _artemis create_
> # Replace their configuration with the configuration from the attachment
> (brokerA1.xml and etc.)
> # Run this brokers _artemis run_
> # Run ArtemisConsumer from maven project ArtemisClusterMirror.rar in
> attachment
> # Run ArtemisProducer from maven project ArtemisClusterMirror.rar in
> attachment
> # Wait for the producer to finish
> # Turn off consumer
> # Compare the number of messages queue Q1 in brokers A1 and B1
> *Expected Behavior:*
> The number of messages in the queue Q1 is the same (0), it is empty
> *Received Behavior:*
> The queue Q1 in mirror broker B1 contains 50 messages that were sent by the
> producer. There were no signals to delete these messages from broker A1 when
> moving them to another cluster broker A2 (with consumer). Screenshots in
> attachment.
> It is also not clear why the internal cluster queues with the _notif_ prefix
> are mirrored, in theory they should not. They also often contain messages
> that are not in the main broker.
