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|
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.
gem install sidekiq

Every Friday morning 9am Pacific is Sidekiq happy hour: I video chat and answer questions. See the Sidekiq support page.
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.
