What are Queues and Job workers?

Laravel queues provide a unified API across a variety of different queue backends, such as Beanstalk, Amazon SQS, Redis, or even a relational database. Queues allow you to defer/postpone the processing of a time consuming task until a later time. Laravel includes a queue worker that will process new jobs as they are pushed onto the queue. You may run the worker using the queue:work Artisan command.
