One of the things keeping me up at night lately is a worry that our federation links will break, the broker will lose its queues someway and we'll wind up with messages being published that just get dropped.
Is there a way we could define some kind of queue that is setup by default? The only other thing I could think is to just define alternate-exchanges for every exchange, slap a queue on it and set a consumer on it that simply republishes when federated links are established.
Other ideas? The approach I came up with feels rough.
