federation upstream message limit

[Sean Allen]

Are there plans to allow for federation upstreams to set not only a message ttl but a max number of messages?

Hmm, I hadn't thought of that, but it makes sense. I'll file a bug.

Of course, if you control the upstream you can create a policy to do the
same thing.

Assuming the upstream is a queue and not a exchange, correct?

Ah, no, the other way round. Federated exchanges internally use queues
whose name begins with "federation:" to buffer messages in the upstream,
so you could set a max length policy in the upstream to apply to those
queues.

For federated queues it doesn't really make sense to talk about length
limits for buffering, since there isn't really any.
