----------------------------------------------------------------
The idea was to do this with aliasing, to match the 5.x naming scheme onto
Artemis. The Aliasing feature hasn't been fully fleshed out, but off the top
of my head something the following:
{code:title=broker.xml|borderStyle=solid}
<address-setting match="#">
// Apply the alias when the address starts with Consumer
<alias prefix="Consumer.">
<address regexpr="\w*.\w*$"></address>
<queue regexpr="^\w*.\w*></queue>
<alias>
</address-setting>
{code}
This is basically saying for any address that starts with Consumer, use the
address and queue defined by the regexpr.
For example: A client subscribing to "Consumer.A.VirtualTopic.Orders" would map
to an Artemis address "VirtualTopic.Orders" and queue "Consumer.A".
In Artemis FQQN this would be "VirtualTopic.Orders::Consumer.A".
The Alias feature needs more thought, I'm sure that using regexpr in this way
will not be performant nor might it work in all use cases. But you can see
where I am going with this.
