resque-ar-failover

Resque plugin to fail over to ActiveRecord backend for Resque job storage, when Redis is unavailable.

At HotelTonight we use Redis. We love it. We also love Resque. But every once in a while, Redis goes away for a split second, causing issues in our app and making some jobs to fall through the cracks.

Resque-ar-failover deals with this issue by rescueing the exceptions that signal that Resque.enqueue has failed before being able to contact redis. When that happens, we persist the job to our MySQL backend (which is HA ready).

We use MySQL; you don't have to. Any AR adapter will do.

Resque-AR-failover is distributed as a gem. Just drop it in your Gemfile

gem 'resque-ar-failover'

Then make sure you add this migration to your project or run the following command to create the migration automatically.

rails generate resque_ar_failover install
rake db:migrate

And that's it! If redis goes down a new ResqueBackup entry will be added and it will automatically be picked up by your resque workers.
