The Ultimate Guide to Scaling Sidekiq

Before we dive into concrete guidance and advice, let’s start with an overview of Sidekiq’s architecture and the various “levers” we have available to us. We’ll also define some terms we’ll use throughout this guide. Concurrency - The Sidekiq setting that controls the number of threads available to a single Sidekiq process. Swarm - A feature of Sidekiq Enterprise that supports running multiple Sidekiq processes on a single container. Container - A container instance running one or more Sidekiq processes. You might call this a server, service, dyno, pod, etc. We’ll just call them containers. Total concurrency - The total number of Sidekiq threads across all containers and processes.
