ResqueSolo

ResqueSolo is a resque plugin to add unique jobs to resque.

It is a re-write of resque-loner.

It requires resque 1.25 and works with ruby 1.9.3 and later.

It removes the dependency on Resque::Helpers, which is deprecated for resque 2.0.

Install

Add the gem to your Gemfile:

gem 'resque_solo'

Usage

class UpdateCat
  include Resque::Plugins::UniqueJob
  @queue = :cats

  def self.perform(cat_id)
    # do something
  end
end

If you attempt to queue a unique job multiple times, it is ignored:

Resque.enqueue UpdateCat, 1
=> "OK"
Resque.enqueue UpdateCat, 1
=> "EXISTED"
Resque.enqueue UpdateCat, 1
=> "EXISTED"
Resque.size :cats
=> 1
Resque.enqueued? UpdateCat, 1
=> true
Resque.enqueued_in? :dogs, UpdateCat, 1
=> false
