# == Qu adapter for Active Job
#
# Qu is a Ruby library for queuing and processing background jobs. It is
# heavily inspired by delayed_job and Resque. Qu was created to overcome
# some shortcomings in the existing queuing libraries that we experienced.
# The advantages of Qu are: Multiple backends (redis, mongo), jobs are
# requeued when worker is killed, resque-like API.
#
# Read more about Que {here}[https://github.com/bkeepers/qu].
#
# To use Qu set the queue_adapter config to +:qu+.
#
# Rails.application.config.active_job.queue_adapter = :qu
