Subject Message groups pattern - "late" consumers
Date Fri, 30 Jan 2015 13:37:47 GMT

I'm looking for a message pattern - something like message groups. I would
like to have one or more consumers/workers that process messages from a
queue, each message is tied with specific device and needs to be processed
in the order received on a per-device context, so at one time only one
consumer should process messages for specific device. Number of devices and
a number of consumers varies. The problem with message groups is that if I
add a consumer at later stage it will be idle (already running consumers
acquired all groups). How can I prevent this? Or maybe I can use some other
message pattern?

Thank you very much, best regards!
