title: How can I specify different concurrency queues for sidekiq configuration?
body: <p>I have the following sidekiq.yml config file, but I'm not sure how to build a separate queue with lower concurrency.  How can I do this?</p>
  
  <pre><code>---
  :concurrency: 25
  :pidfile: ./tmp/pids/sidekiq.pid
  :logfile: ./log/sidekiq.log
  :queues:
    - default
    - [high_priority, 2]
    - [import_queue, 3]
    - [user_queue, 4]
  :daemon: true
  </code></pre>
  
  <p>I would like to do something like the following though,</p>
