# Active Jobs

# Introduction

Available since Rails 4.2, Active Job is a framework for declaring jobs and making them run on a variety of queuing backends. Recurring or punctual tasks that are not blocking and can be run in parallel are good use cases for Active Jobs.

# Sample Job

class UserUnsubscribeJob < ApplicationJob
  queue_as :default

  def perform(user)
    # this will happen later

# Creating an Active Job via the generator

$ rails g job user_unsubscribe
