Sidekiq::Throttled::Worker

Sidekiq concurrency limit per worker in whole cluster, inspired by sidekiq-throttled. This gem only support concurrency, and try to avoid use lua in redis to reduce redis CPU usage.

This gem was designed to limit concurrency for some sensitive resources, e.g., databases and http requests, without concurrency limit, sidekiq may crush this services. When some worker exceed concurrency limit, this gem may try to slow down sidekiq process.

Add this line to your application's Gemfile:

gem 'sidekiq-throttled-worker'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install sidekiq-throttled-worker

After Sidekiq configure_server，you should add next line in sidekiq initializer

Sidekiq::ThrottledWorker.setup!

This gem add two options attr in sidekiq_options func：

• concurrency : limit concurrency with current worker in whole cluster. Default is nil , which mean on limit
• concurrency_ttl : max worker run time, and worker may be block completely max for concurrency_ttl in extreme case. Default is 900, in most cases, you do not need change this.

Here is an example worker

class TestWorker
  include Sidekiq::Worker
  sidekiq_options queue: :default, concurrency: 2

  def perform
  end
end
