Sidekiq is a framework for background job processing. It allows you to scale your application by performing work in the background. For more information on Sidekiq, consult the following website: https://github.com/mperham/sidekiq/wiki.

Each Sidekiq server process pulls jobs from the queue in Redis and processes them. Like your web processes, Sidekiq boots Rails so that your jobs and workers have the full Rails API available for use, including ActiveRecord. The server will instantiate the worker and call perform with the given arguments. Everything else is up to your code.
