Even distribution of messages at consumer level?

[nazmul-prince]

Lets say we have 4 producer (of same instance) who are en-queuing messages to a queue. There are 4 consumer (of same instance) with concurrency limit set to 20-25 in each consumer @RqueueListener settings. Now is it guaranteed that all consumers will get messages evenly? Or is there any way to achieve such goal so that all consumers get messages evenly from the queue like round-robin process?
