Here's a list of the rake tasks you can perform with delayed job. The source code that I pulled this list from is delayed_job/lib/delayed/tasks.rb.
- rake jobs:clear
- Clear the delayed_job queue.
- rake jobs:work
- Start a delayed_job worker.
- rake jobs:workoff
- Start a delayed_job worker and exit when all available jobs are complete.
- rake jobs:check
- Exit with error status if any jobs older than max_age seconds haven't been attempted yet.
