[rabbitmq-discuss] Symmetric federation behavior

[Busoli, Simone]

Well, what leads me to think that it's still behaving as before is that I see messages being published on the "federation: ..." queues on both brokers.
I am assuming it is behaving as before because this is what happens when I just the remove the exchange federation configuration, but if I remove the upstream-sets entry as well the broker will crash at startup. I am under the impression that there's no way to unfederate an exchange actually, perhaps because it is a durable exchange maybe?

Well, it will still claim to be a federated exchange, but if you don't define any upstreams for it then it won't actually federate. Is that what you mean by "the exchange is still there with federation set-up"?

Sadly the code to let you monitor running federation links hasn't made it into any releases yet so the only way to see if federation is actually happening is to look for messages in the logs along the lines of "Federation exchange foo connected to blah" at startup. There shouldn't be any.

Cheers, Simon
