There are multiple ways to achieve this. Probably the simplest and most reliable is to rely on cron to run your process every minute. Cron keeps track of time and executes your script each minute. This has the added benefit of avoiding a long running process (which can have its own issues). You can even have your script install it’s own cron job using the Whenever gem.

Rake tasks can be called from Cron, so we'll use the Whenever Gem to automatically add our job to our Crontab during deployment, and keep our schedule in change control.
