ActiveJob::Scheduler

An extension to ActiveJob for running background jobs periodically, according to a schedule. Inspired by its predecessors, resque-scheduler and sidekiq-scheduler, ActiveJob::Scheduler hopes to bring the power of scheduled jobs into everyone's hands, by way of the pre-defined ActiveJob API which most popular queueing backend choices already support.

Like its predecessors, ActiveJob::Scheduler is built with Rufus::Scheduler, an immensely powerful task scheduling library to make sure your jobs get kicked off at exactly the right time.

Installation

Add this line to your application's Gemfile:

gem 'activejob-scheduler'

And then execute:

$ bundle

Usage

Run the following command to generate a YAML-based schedule:

$ rails generate activejob:schedule

Edit this YAML file the same way you would with resque-scheduler or sidekiq-scheduler (they define the same parameters). Then, it's your choice as to how you wish to run it, either by the binary:

$ bundle exec ajs

Or, with a Rake task:

$ bundle exec rake activejob:schedule

The schedule must run as a separate process, but it's very light...it delegates all the real processing to your queue workers, and simply enqueues jobs as the specified time rolls around.
