title: Laravel Vapor queue-concurrency
body: <p>Just checking what happens when we hit queue-concurrency limit.</p>
  <p>For example if I had a cron that added 100 items to my queue.</p>
  <pre><code>queue-concurrency=25
  </code></pre>
  <p>Would aws throw out the extra 75?
  Or does it just limit concurrency to 25 at once and still process them all?</p>
  <p>I get regular concurrency limit is for ddos protection but for queues this could be an issue.</p>
