It would be good to be able to support clustering without multicast
(not just for EC2). Would other toolkits that claim to support virtual
synchrony with unicast (as well as multicast) be suitable as
replacements for openais? e.g. Spread http://www.spread.org
Ais/corosync supports RDMA in it's next release which will open up that
option without
coding on Qpid, just config on AIS. It also gets to IB and iWARP at
higher rates and
better latency on a cluster.
In early testing I've seen end-end (producer to consumer) latencies
through a cluster under load
at about 40us
It would be better to make additional requests on the corosync project,
as they have supported
Qpid quite well with fixes and enhancements.
