Rake::Multiple

Rake::Multiple is the easiest way to run the same Rake task in multiple forked processes. It's particularly useful if your app is hosted on a PaaS provider, such as Heroku, and you want to run multiple worker processes by container, saving money.

Add this line to your application's Gemfile:

gem 'rake-multiple'

And then execute:

$ bundle

Rake::Multiple can invoke any task by prefixing the multiple namespace to the task. So if you're running:

rake jobs:work

You can then run two processes in your app with the following command:

MULTIPLE_WORKER_COUNT=2 rake multiple:jobs:work

If your tasks need has dependencies, you can run a specific dependency by using the MULTIPLE_EXECUTE_TASK variable.

MULTIPLE_WORKER_COUNT=2 MULTIPLE_EXECUTE_TASK=environment rake multiple:jobs:work
