Autoscaling workers for delayed_job in Rails 3

I've been using collectiveidea's fork of delaye开发者_开发技巧d_job as a gem in my Rails 3 app, and it's working fine. I'm now looking for a solution to autoscale workers, specifically for Heroku. I've given pedro's fork a try but since it's written for Rails 2, using it throws lots of errors and warnings about deprecated methods and I haven't been able to get it to work successfully.

Is there a working solution for Rails 3 delayed_job with autoscaling workers?

You might want to take a look at workless, it's one of the only Rails3 worker autoscalers I've seen at this point.

Specifically for heroku, check out "HireFire - The Heroku Worker Manager" and hirefireapp service:

• https://github.com/meskyanichi/hirefire - open source
• http://hirefireapp.com/ - service in public beta now

I've started working on a gem called Komodo to perform that very same task for un upcoming project at work. However, since we've only just started on the project, the gem is still very, very early - and untested.

I should see some consistent updating over the next couple of weeks though - would certainly appreciate any feedback or contributions! :)
