Description

Need to replicate queue state between two clusters (or potentially two
non-clustered brokers); one of these is the primary site, the second
is a disaster recovery site. They will likely be connected over a WAN.

Two modes are required to be supported concurrently on a per queue
basis:

only messages flowing into the queue need to be replicated; the DR
site will have active replicas of the consumers of such queues that
will be receiving and consuming them.

(ii) full queue state needs to be replicated, i.e. both the enqueing
and dequeuing of messages on the primary site needs to be reflected in
the DRs replica of the queue.
