Adapted from: Auto-scale Your Resque Workers On Heroku
job_counts is list that is used to define how many jobs are run for the number of workers as determined by the index in the list:
HerokuResque::AutoScale.job_counts = 22 # 22 max jobs for 2 workers HerokuResque::AutoScale.job_counts = [1,4,8,16,32,64] # load jobcounts list from config/heroku/worker_auto_scale.yml HerokuResque::AutoScale.job_counts = HerokuResque::AutoScale::Loader.job_counts # or configure filename to use before load HerokuResque::AutoScale::Loader.file_name = 'job_counts.yml' HerokuResque::AutoScale.load_job_counts!
class ScalingJob extend HerokuResque::AutoScale def self.perform # Do something long running end end
Configure Heroku stack used
By default this gem assumes you are running on the 'cedar' stack. You can customize the Heroku stack used like this:
HerokuStack.name = 'my-stack'
We might have to adjust the code in
scaler.rborder to support Heroku stacks with different Process models in the future...
Contributing to heroku-auto_scale
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
