title: Multiple Queues in Laravel
body: <p>I am creating a web application in laravel in which bidding is being done by users in multiple games. Bidding is being performed by front end users and by cron job as well. Cron job do bid on each game after each second. Therefore some collision was happening between bids when same row was accessed at same time. To resolve concurrency issue I decided to use laravel queues for bidding. But I am having multiple games and therefore I want simultaneously bids of each game. I don't want bids of same game to be process at same time because then concurrency issue can be occur. I want to know about multiple queues system in laravel. After having search on internet I got to know about multiple queues like</p>
  
  <pre><code>php artisan queue:work --queue=myJobQueue, myJobQueue1, myJobQueue2,..myJobQueue7
  </code></pre>
  
  <p>But I am not sure how it works. Please someone explain me in detail that all 7 queues work simultaneously or one by one.</p>
