Subject Broker Networks and duplicate message delivery
Date Thu, 15 Dec 2011 18:47:30 GMT

As I understand,broker networks could be configured with bidirectional
message push for cross-geographic fail over of message processing through
the store-and-forward method. So, if broker A and B form a simple 2-member
network,possibly over a WAN (spanning multiple geographies), with
bidirectional push enabled, how do we ensure that a given message M sent to
A or B is processed only once? If the message is originally published to A,
it'd first be stored there and then forwarded to B.Now, assuming both A and
B have consumers attached to them, M would get delivered and hence processed
twice. How do I prevent this duplicate processing?Am I missing anything
