Simple, efficient message processing for Ruby.
Sidekiq aims to be a drop-in replacement for Resque. It uses the exact same
message format as Resque so it can slowly replace an existing Resque processing farm.
You can have Sidekiq and Resque run side-by-side at the same time and
2012-01-23 23:56:06 -05:00
use the Resque client to enqueue messages in Redis to be processed by Sidekiq.
2012-01-21 19:42:21 -05:00
Sidekiq is different from Resque in how it processes messages: it
processes many messages concurrently per process. Resque only processes
one message at a time per process so it is far less memory efficient.
You'll find that you might need 50 200MB resque processes to peg your CPU
whereas one 300MB Sidekiq process will peg the same CPU and perform the
same amount of work. Please see [my blog post on Resque's memory
efficiency](http://blog.carbonfive.com/2011/09/16/improving-resques-memory-efficiency/)

and how I was able to shrink a Carbon Five client's resque processing farm

from 9 machines to 1 machine.
Requirements

I test on Ruby 1.9.3 and JRuby 1.6.5 in 1.9 mode. Other versions/VMs are
untested.
