they are the same as for any other queue, just put inside main_queue()
instead of action() or ruleset()

given that all your traffic goes to a different queue, I would consider
adding queue.dequeueslowdown as some smallish value just so the worker
isn't in a tight loop locking the main queue. I'd try 500us as a starting
point. that will limit your throughput to < 2000batches/sec * 128
messages/batch or probably somewhere around 200K messages/sec (high enough
relative to your other numbers that it shouldn't be the limiting factor)
