Ruby on Rails Background Jobs with Sidekiq

Run Code Later without Complicating Your App

an EBook by David Bryant Copeland

  • 🤔 Are users waiting on services like payment processing?

    🙋‍♂️ Learn to put code in a background job to better manage your infrastructure.

  • 😩 Getting alerted about failing jobs, but don't know what to do?

    🙋 Configure Sidekiq and your jobs to notify you only when you need to know.

  • 💸 Are you double-charging your customers when there's a network outage?

    🙋‍♀️ Re-design your code so that jobs can be safely retried by picking up where they left off…without bothering you.

  • 😵‍💫 Redis, worker processes, failing jobs…not sure how to monitor all this?

    🙋 Learn which metrics are critical—and which aren't—about your Sidekiq installation.

Using a background job system like Sidekiq requires more than just throwing code into a perform method. It means you have a distributed system…and all the complexity that goes with it.

This book has 70 pages packed with pratical, actionable advice, based on my experience managing large background job systems. You'll jump right into getting Sidekiq set up, then putting code into an example app that exhibits all the failures you'll find in the real world.

  1. Create a foundational Sidekiq configuration suitable for production. 🏛️
  2. See jobs fail, then learn how to keep them from notifying you…but without just forgetting about them. 🚨
  3. Watch jobs get retried and wreak havoc inside your app, then fix them by applying a step-by-step process to understand idempotency—the degree to which your code will only have its effects felt once. 🔄
  4. Learn how to organize job code, monitor the right things, and set yourself up to sustainably operate Sidekiq. 📊
