[rabbitmq-discuss] Federation chokes on load

[Simon MacMullen]

Hi Patrik, thanks.

So this looks like federation is configured correctly and should be 
working normally. The downstream exchange only has a single binding to a 
single queue, with routing key "user.2". Are messages being published 
upstream with that key?

Cheers, Simon
