title: How to control concurrency per queue?
body: <p>Sidekiq documentation suggests I can only control the global concurrency of sidekiq, rather than per queue. I am raising a question here with hope that there's a solution for a per-queue concurrency setting. Some 3rd party services just won't accept high concurrency, and limiting the entire sidekiq just for those is painful.</p>
  
  <p>I'm on sidekiq 3.3</p>
