Docker

Merge sidekiq jobs occurring before the execution times. Inspired by sidekiq-grouping.

Installation

Add this line to your application's Gemfile:

gem 'sidekiq-merger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sidekiq-merger

Usage

Add merger option into your workers.

class SomeWorker
  include Sidekiq::Worker

  sidekiq_options merger: { key: -> (args) { args[0] } }

  def perform(*merged_args)
    merged_args.each do |args|
      # Do something
    end
  end
end

Then, enqueue jobs by perform_in or perform_at.

SomeWorker.perform_in 100, 4
SomeWorker.perform_in 100, 3
SomeWorker.perform_in 100, 5
# Passed 100 seconds from the first enqueue.
SomeWorker.perform_in 100, 6
SomeWorker.perform_in 100, 1

SomeWorker will be executed in 100 seconds with args of [4], [3], [5], then with args of [6], [1].

perform_async works without merging args.

SomeWorker.perform_async 4
SomeWorker.perform_async 3
SomeWorker.perform_async 5

In this case, SomeWorker will be executed 3 times with args of [4], [3] and [5].

Quick Check

Run docker containers to check the behavior of this gem.

$ docker-compose up

Then, open http://localhost:3000/. You can push jobs from the UI and see what happens in the sidekiq console.

Options

key (optional, default: nil)

Defines merge key so different arguments can be merged.

Format: String or Proc

e.g. sidekiq_options merger: { key: -> (args) { args[0..1] } }

unique (optional, default: false)

Prevents enqueue of jobs with identical arguments.

Format: Boolean

e.g. true
