Sidekiq::Clockwork

Sidekiq::Clockwork is a simplistic implementation of a job scheduler based on Clockwork, but without having to run a separated process.

Installation

Add this line to your application's Gemfile:

gem "sidekiq-clockwork"

And then execute:

$ bundle

Or install it yourself as:

$ gem install sidekiq-clockwork

Usage

Create your job scheduler and make sure that it's loaded by Sidekiq's server (when you run the sidekiq command).

Sidekiq::Clockwork.run do
  # This is the default timeout
  # sleep_timeout 0.1

  # By default, it comes with a error handler like the following:
  # error_handler do |error|
  #   $stderr << "[CLOCKWORK] #{error.class}: #{error.message}"
  #   $stderr << " (" << error.backtrace_locations.first << ")\n"
  # end
  #
  # You can clean up error handlers with:
  # error_handlers.clear
  #
  # You may want to use an exception tracker like Rollbar:
  # error_handler do |error|
  #   Rollbar.error(error)
  # end
  #

  # You can schedule jobs by using `every`, which receives
  # an interval in seconds.
  every(30.seconds) { SomeWorker.perform_async }
end

Sidekiq::Clockwork is single-threaded and sequencial by design, so make sure your scheduler only enqueue jobs without doing any processing (tl;dr make it as fast as you can).

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
