Simple, efficient message processing for Ruby.
|
|
|
|
Sidekiq uses threads to handle many messages at the same time in the
|
|
same process. It does not require Rails but will integrate tightly with
|
|
Rails 3 to make background message 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 messages in Redis to be processed by Sidekiq.
|
|
|
|
At the same time, Sidekiq uses multithreading so it is much more memory efficient than
|
|
Resque (which forks a new process for every job). 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.x in 1.9 mode. Other versions/VMs are
|
|
untested but I will do my best to support them. Ruby 1.8 is not supported.
|
|
|
|
Redis 2.0 or greater is required.
