Is there anything like DelayedJob, but not use Database

Question

I'm building a web site with Rails, which will do something in the background. I don't want to use DelayedJob, because it needs a database.

What I wan't to do is simple: get some data from another site, save the response in the memory, and keep it for 10 minutes.

Is there any tools can do this?

Answer 1

Use resque http://github.com/defunkt/resque. It uses a redis backed data store rather than the database.

Answer 2

You can use a rake task in background to do this. Run it as a cron job or a daemon to perform tasks in the background.

Answer 3

You might want also want to try whenever. It's basically a ruby script that writes the scheduled job to cron.
