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, allowing a web-serving thread to continue serving new requests rather than be blocked processing slower tasks.

Reception and use

Sidekiq is described as a “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]
