    #interrupt_job_after_step(job, step, &block)  
  



  

    

Interrupt a job after a step.



Note that there’s no checkpoint after the final step so it won’t be interrupted.



class MyJob < ApplicationJob
  include ActiveJob::Continuable

  cattr_accessor :items, default: []

  def perform
    step :step_one { items << 1 }
    step :step_two { items << 2 }
    step :step_three { items << 3 }
    step :step_four { items << 4 }
  end
end

  MyJob.perform_later
  interrupt_job_after_step(MyJob, :step_two) { perform_enqueued_jobs }

    #interrupt_job_during_step(job, step, cursor: nil, &block)  
  



  

    

Interrupt a job during a step.

    step :my_step, start: 1 do |step|
      (step.cursor..10).each do |i|
