• ActiveJob::Base.deserialize delegates to the job class

  Since ActiveJob::Base#deserialize can be overriden by subclasses (like ActiveJob::Base#serialize) this allows jobs to attach arbitrary metadata when they get serialized and read it back when they get performed. E.g.

  class DeliverWebhookJob < ActiveJob::Base
    def serialize
      super.merge('attempt_number' => (@attempt_number || 0) + 1)
    end
  
    def deserialize(job_data)
      super(job_data)
      @attempt_number = job_data['attempt_number']
    end
  
    rescue_from(TimeoutError) do |ex|
      raise ex if @attempt_number > 5
      retry_job(wait: 10)
    end
  end
