> Conflation queues replace messages with new one as they arrive if the two 
> messages share the same key value
> A conflation queue is created if you specify a <conflationKey> in the XML 
> configuration; or provide a value for x-qpid-conflation-key in the arguments 
> to the Queue.Declare command.
> A queue thus created will check incoming messages as they come in for the 
> value in the application headers associated with the given conflationKey.  
> Any message with the same conflation key value which has not yet been 
> dequeued will be dequeued immediately as the new message is inserted into the 
> queue.
> Using a non-acquiring consumer (i.e. browsing) one can use a conflation queue 
> as an LVQ which also sends updates as new values are inserted/updated.
