Description

Sidekiq strategy to restrict number of workers which are able to run specified queues simultaneously.

Installation

Add this line to your application's Gemfile:

gem 'sidekiq-limit_fetch'

Usage

Specify limits which you want to place on queues inside sidekiq.yml:

:limits:
  queue_name1: 5
  queue_name2: 10

Or set it dynamically in your code:

  Sidekiq::Queue.new('queue_name1').limit = 5
  Sidekiq::Queue['queue_name2'].limit = 10

In these examples, tasks for the queue_name1 will be run by at most 5 workers at the same time and the queue_name2 will have no more than 10 workers simultaneously.

Ability to set limits dynamically allows you to resize worker distribution among queues any time you want.

Limits are applied strictly for current process.
