Subject Re: Network of Brokers: XAException on Failover
Date Thu, 01 Oct 2015 13:06:03 GMT
A network of brokers can be used for HA as long as the network topology
will remain fully connected in the face of N failures (for whatever value
of N you choose to support, probably 1) and the clients' failover URIs will
always contain a live broker in the face of the same failure(s).

But you could also consider master/slave pairs using LevelDB as the storage
technology, which doesn't have a single point of failure.
