Resque Waiting Room

A Resque plugin. Requires Resque >= 1.19 and a >= 1.9 Ruby (MRI, JRuby or Rubinius).

If you want to limit the number of performs of a job for a given period, extend it with this module.


Add this line to your application's Gemfile:

gem 'resque-waiting-room'

And then execute:

$ bundle

Or install it yourself as:

$ gem install resque-waiting-room


Example -- 10 jobs processed every 30 seconds max

require 'resque/plugins/waiting_room'

class UpdateDataFromExternalAPI
  extend Resque::Plugins::WaitingRoom

  # This job can be performed 10 times every 30 seconds
  can_be_performed times: 10, period: 30

  def self.perform(repo_id)

If 10 UpdateDataFromExternalAPI jobs have been performed in 20 seconds, for the next 10 seconds UpdateDataFromExternalAPI jobs will be placed in the waiting_room queue and processed when possible. When the first 30 seconds are elapsed, the counter is set back to 0 and 10 jobs can be performed again. You got to manually tweak the queue names in your workers though.


We include a matcher

require 'spec/support/matchers'

describe MyJob do
  it 'is rate limited' do
    MyJob.should be_only_performed(times: 100, period: 300)

Run tests with the following command

bundle exec rake


  1. Fork it
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Added some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request
