Question about QOS about op-rabbit HOT 2 CLOSED

More context in case it helps; What I ultimately would like to do is have some kind of Round Robin load balancing across multiple RMQ instances. For example, if there are instances at 192.168.1.10 and 192.168.1.11, I want to be able to load balance across both equally (if I have 50 messages, I want 25 to go onto each RMQ instance). It doesn't look like I can do that out of the box so I am trying to dissect this and configure it appropriately.

Hi @haggy , just reading your question now.

qos is purely a RabbitMQ server concern; op-rabbit passes it to the server and the server manages it.

Using the value to limit concurrent messages processed on an instance will help to support an even distribution of messages by time-to-process messages, but I'm not aware of a built-in mechanism which will provide even round-robin delivery. (there is a plugin that could help with it, though, which allows you to create a round-robin exchange that delivers messages evenly amongst bound queues).
