Using Sidekiq for background jobs is a great way to scale and grow your app. This book will give you a solid, practical foundation for creating resilient, well-tested, self-healing code that uses background jobs. You’ll be able to simulate real-world failure modes and learn how to write idempotent code that can be safely run with Sidekiq.

Great book for devs starting with Sidekiq, but it contains some nice tips for people that have been using it for some time. It’s a short book, so it’s worth to read it.
