Simple, efficient background processing for Ruby.
2012-01-21 19:42:21 -05:00
2013-06-26 00:55:51 -04:00
Sidekiq uses threads to handle many jobs at the same time in the
2012-08-31 00:02:49 -04:00
same process. It does not require Rails but will integrate tightly with
2016-02-22 23:34:16 -05:00
Rails to make background processing dead simple.
2012-04-05 22:20:24 -04:00
2012-03-26 09:26:05 -04:00
Sidekiq is compatible with Resque. It uses the exact same
2012-02-05 10:55:18 -05:00
message format as Resque so it can integrate into an existing Resque processing farm.
2012-01-21 19:42:21 -05:00
You can have Sidekiq and Resque run side-by-side at the same time and
2013-06-26 00:55:51 -04:00
use the Resque client to enqueue jobs in Redis to be processed by Sidekiq.

Sidekiq stays fast by using the [JProfiler java profiler ](http://www.ej-technologies.com/products/jprofiler/overview.html ) to find and fix
2015-10-30 16:41:18 -04:00
performance problems on JRuby. Unfortunately MRI does not have good multithreaded profiling tools.
