    # == Que adapter for Active Job
    #
    # Que is a high-performance alternative to DelayedJob or QueueClassic that
    # improves the reliability of your application by protecting your jobs with
    # the same ACID guarantees as the rest of your data. Que is a queue for
    # Ruby and PostgreSQL that manages jobs using advisory locks.
    #
    # Read more about Que {here}[https://github.com/chanks/que].
    #
    # To use Que set the queue_adapter config to +:que+.
    #
    #   Rails.application.config.active_job.queue_adapter = :que
