As I added a feature 2 releases ago, (Broker Connection with Mirror support), I am further enhancing Mirror support in Artemis.
So far the failback would be determined by activating a Mirror option on the way back. To cut a long story short, you should always have only one Mirror option enabled. (Having it both ways would cause the broker to ping / pong messages in an infinite loop on a few cases). So, I am improving things a bit. It will be possible to have the mirror configured both ways. That way a broker pair would always be in sync... both nodes would be Live, hot and ready to go. I wouldn't recommend both nodes receiving connections from clients... but you could either enable or disable routes on TCP or some cloud option... or you could enable / disable acceptors that are responsible for clients. then you could have another acceptor to just connect the nodes... And whatever happens in one node, gets sent to the other node. It will be a really nice improvement on Mirror support. and I plan to have this ready before the next release. I should add some blogging about this.. it's a really nice feature. -- Clebert Suconic
