Does Flespi publisher recognize a non-success reason code returned by the subscriber?
Please advise. I would expect it re-routing the message to the other servers in the group. My testing shows that it does not. If it does not, which backpressure mechanisms can be used, except the obvious ones - unsubscribing, delaying the response, and abandoning the PUBACK? Can one publish the rejected message to a dedicated custom topic so that other servers in the group picked it up and processed the message?
Please advise.
Thanks.
