Sidekiq Job Signal

Signal a job to quit, and block the job from executing through middleware.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add sidekiq-job-signal

In your Gemfile, specify the gem as:

gem "sidekiq-job-signal", require: "sidekiq/job_signal"

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install sidekiq-job-signal

Usage

Sidekiq::JobSignal.quit(jid: "12345")
Sidekiq::JobSignal.quit(job_class: "ExampleJob")

# log:
#   Turned #{12345}:#{JobWorkerClass} into a no-op: [1,2,3]"

# If you want to add the `quitting?` method to your job
class ExampleJob
  include Sidekiq::Job
  include Sidekiq::JobSignal::Receiver

  def perform
    if quitting?
      # finish early...
    end
  end
end

# middleware.rb
Sidekiq.configure_server do |config|
  config.server_middleware do |chain|
    # Defaults to by_class: false, by_jid: true
    chain.add ::Sidekiq::JobSignal::ServerMiddleware
    # OR
    chain.add ::Sidekiq::JobSignal::ServerMiddleware, by_class: true
    # OR
    chain.add ::Sidekiq::JobSignal::ServerMiddleware, by_jid: false, by_class: true
  end

  Sidekiq::JobSignal.on_quit do |job|
    Sidekiq.logger.info "Job was cancelled!"
    Sidekiq.logger.info job
  end
end

If you'd like to enable the Sidekiq Web UI for quitting jobs, you can include the following in some kind of initialization file. This will enable a new "Signals" tab.

Sidekiq::Web.register Sidekiq::JobSignal::Web
