Sidekiq

Gem Version Code Climate Build Status Gitter Chat

Simple, efficient background processing for Ruby.

Sidekiq uses threads to handle many jobs at the same time in the same process. It does not require Rails but will integrate tightly with Rails 3/4 to make background processing dead simple.

Sidekiq is compatible with Resque. It uses the exact same message format as Resque so it can integrate into an existing Resque processing farm. You can have Sidekiq and Resque run side-by-side at the same time and use the Resque client to enqueue jobs in Redis to be processed by Sidekiq.

Sidekiq is fast.

Version Latency Garbage created for 10,000 jobs Time to process 100,000 jobs Throughput
Sidekiq 4.0.0 10ms 151 MB 22 sec 4500 jobs/sec
Sidekiq 3.5.1 22ms 1257 MB 125 sec 800 jobs/sec
Resque 1.25.2 - - 420 sec 240 jobs/sec
DelayedJob 4.1.1 - - 465 sec 215 jobs/sec

Requirements

I test with the latest CRuby (2.2, 2.1 and 2.0) and JRuby versions (9k). Other versions/VMs are untested but might work fine. CRuby 1.9 is not supported.

All Rails releases from 3.2 are officially supported.

Redis 2.8 or greater is required. 3.0.3+ is recommended for large installations with thousands of worker threads.

Installation

gem install sidekiq

Getting Started

See the Getting Started wiki page and follow the simple setup process. You can watch Railscast #366 to see Sidekiq in action. If you do everything right, you should see this:

Want to Upgrade?

I also sell Sidekiq Pro and Sidekiq Enterprise, extensions to Sidekiq which provide more features, a commercial-friendly license and allow you to support high quality open source development all at the same time. Please see the Sidekiq homepage for more detail.

More Information

Please see the sidekiq wiki for the official documentation. mperham/sidekiq on Gitter is dedicated to this project, but bug reports or feature requests suggestions should still go through issues on Github. Release announcements are made to the @sidekiq Twitter account.

You may also find useful a Reddit area dedicated to Sidekiq discussion and a Sidekiq tag on Stack Overflow.

Problems?

Please do not directly email any Sidekiq committers with questions or problems. A community is best served when discussions are held in public.

If you have a problem, please review the FAQ and Troubleshooting wiki pages. Searching the issues for your problem is also a good idea. If that doesn't help, feel free to email the Sidekiq mailing list, chat in Gitter, or open a new issue. StackOverflow or Reddit is the preferred place to ask questions on usage. If you are encountering what you think is a bug, please open an issue.

Thanks

Sidekiq stays fast by using the JProfiler java profiler to find and fix performance problems on JRuby. Unfortunately MRI does not have good multithreaded profiling tools.
