Overview

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. The advantages of Qu are: Multiple backends (redis, mongo), jobs are requeued when worker is killed, resque-like API.
