That's not the case. Each node knows about every consumer on every other node, including it's selector. By default JBM will never route messages to a node which doesn't have matching consumers.

You can turn that behaviour off by setting routeWhenNoConsumers = true in the cluster config (see docs).

I don't know, but I know Paxos has been studied over many years by many computer scientists, so I'd be sceptical whether our requirements are satisfied by a completely different algorithm. Most likely your algorithm is already one of the variants or your algorithm doesn't satisfy one of our requirements fully.
