Sidekiq

Sidekiq is an open source job scheduler written in Ruby.[3] It's important to be aware that Sidekiq by default doesn't do scheduling, it only executes jobs. The Enterprise version comes with scheduling out of the box.

Architecture

Sidekiq uses Redis as an in-memory data structure store and is written in Ruby.[4] It also supports Java clients.[4] It can be used with Resque, another Redis based job scheduler, or more commonly as a standalone product.

Sidekiq reads jobs from a Redis queue, using the First In First Out (FIFO) model, to process jobs. Job processing is asynchronous and allows a web thread serve requests, rather than process heavy tasks.

Reception and use

Sidekiq is described as “well-known queue processing software”.[4]

It's used by Ruby applications needing to run tasks in the background, and not in the web requests handling time, like Mastodon, Diaspora,[5] GitLab and Discourse. Sidekiq is also used to submit threads to the PHASTER phage search tool.[6]
