Subject Re: Using queue to support disconnected clients

hmm, that is an interesting use case, a concentrator. At the moment
all destinations are global so the will map one to one across the
network.

I don' think there is a way to configure a concentrator out of the box
but all of the component bits are there so you should be able to make
it work with a bit of customisation.

You would need to have the client forwarding bridge contain a
statically included composite destination, using a comma separated
list of client q destinations. This will subscribe to and shunt all of
the messages from client q's to the server side,  however the target
destination will need to be replaced to implement the concentrator.

On the server side, you will need a broker plugin that intercepts the
send operation and maps the X client q destinations to the shared q.

An alternative approach would be to implement the mapping in the
client broker (in configuration) via virtual destinations, so you
configure all of the client destinations to internally forward to a
shared queue and then propagate just that shared queue through the
network.

If there is no value in the client queue destinations, you could put
in a broker plugin on the client that replaces the destinations at
that point an be done with it.

So you have a few options, depending on your exact use case, the
plugin architecture gives you complete control really.
