@LoudCaster very good point, when running on Rackspace Cloud servers I used a separate script to kick off the background jobs. On Heroku I think a custom rake task would probably be a better way to do this.

If you plan on running more than one worker, it might be better to kick off the seed job from a rake task rather than application startup. Otherwise you'll end up running the action concurrently xN times.

@Jay, not sure how that happened, when I did it, it was $15/month for one thread, but maybe they changed the pricing. I eventually had to move my application to Rackspace's cloud because I needed more than 1 thread (which I think Heroku supports now, but didn't then).

How did you determine the cost to be $15/month?

When I tried adding a DelayedJob to my app, I was forced to add 1 "Worker" (using Heroku's terminology) and my monthly cost went from $0 to $36!

I posted this on Heroku support, but another simple way of doing this is just to schedule another job at the end of the perform method.

I found that creating my recurring job during after_initialize was messy... (what if you start the app in the console while it's running on the server?). So I created a rake task to create my first job. Once the first job is created, then running rake jobs:work will just pick up where you left off. No need worrying about creating a duplicate job.

FYI, you can also just do Delayed::Job.destroy_all. You can use any of the ActiveRecord methods: http://api.rubyonrails.org/classes/ActiveRecord/Base.html

Thanks for the tip about setting the run time for jobs. I didn't know you could do that!
