Active Job with Sidekiq

Active Job

• Active Job is a framework for declaring jobs and making them run on a variety of queuing backends.

• Rails by default comes with an asynchronous queuing implementation that runs jobs with an in-process thread pool. Jobs will run asynchronously, but any jobs in the queue will be dropped upon restart.

• Active Job has built-in adapters for queuing backend as:

  • Sidekiq
  • Resque
  • Delayed Job
  • Others

Sidekiq

• Sidekiq is a full-featured background processing framework for Ruby.

• Sidekiq uses threads to handle many jobs at the same time in the same process.

Usage

1. Add gem 'sidekiq'

2. Add sidekiq.rb to config/initializers/

Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://localhost:6379' }
end

Sidekiq.configure_client do |config|
  config.redis = { url: 'redis://localhost:6379' }
end

Redis url format: 'redis://[ip-host]:[port]'

3. Setting queue adapter in config/application.rb

module SidekiqApp
  class Application < Rails::Application
    # Be sure to have the adapter's gem in your Gemfile
    # and follow the adapter's specific installation
    # and deployment instructions.
    config.active_job.queue_adapter = :sidekiq
  end
end

4. Advance configuration: config/sidekiq.yml
