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 have too many types of jobs, and can't make sure all of them are thread safe. So I want to run Delayed Job and Sidekiq in parallel, and migrating one type of job at a time.

Since both Delayed Job and Sidekiq offers the .delay method, how can I make the distinction between the two? Are there any other potential issues?

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.
