Run Delayed Jobs and Sidekiq at the same time

Question

I currently use delayed job to process jobs asynchronously. Instead of creating workers, I use the .delay method a lot.

I want to move to Sidekiq, but I

Answer 1

For Sidekiq 2.17.1 and later, somewhere in the Rails initializers, call the following:

Sidekiq.hook_rails!
Sidekiq.remove_delay!

and you will have only prefixed sidekiq_delay methods and so on.

For older versions of Sidekiq:

Put the following in config/initializers/sidekiq.rb

module Sidekiq::Extensions::Klass
  alias :sidekiq_delay :delay
  remove_method :delay
  alias :sidekiq_delay_for :delay_for
  remove_method :delay_for
  alias :sidekiq_delay_until :delay_until
  remove_method :delay_until
end

module Sidekiq::Extensions::ActiveRecord
  alias :sidekiq_delay :delay
  remove_method :delay
  alias :sidekiq_delay_for :delay_for
  remove_method :delay_for
  alias :sidekiq_delay_until :delay_until
  remove_method :delay_until
end

module Sidekiq::Extensions::ActionMailer
  alias :sidekiq_delay :delay
  remove_method :delay
  alias :sidekiq_delay_for :delay_for
  remove_method :delay_for
  alias :sidekiq_delay_until :delay_until
  remove_method :delay_until
end

And then you can use sidekiq_delay to queue in Sidekiq, and call delay to queue in Delayed Job.

Answer 2

For anyone searching for this. I did find Sidekiq now has a setting for this out of the box. All you need to do is add Sidekiq.remove_delay! to config/initializers/sidekiq.rb

This is described here: https://github.com/mperham/sidekiq/wiki/Delayed-Extensions

Answer 3

It seems that Sidekiq has mix-in that adds .delay methods to all classes. Not 100% sure how this will behave but it could result in problems if delay you are refering to is on the instance level.

My advice would be to add sidekiq library per job until you have moved all you jobs to it. Meaning to avoid including both libraries at the same time, again if possible.
