Question

I’ve seen several solutions for doing this:

1. Redis / Resque
2. Delayed Job
3. Heroku Scheduler
4. Clockwork

Heroku scheduler won’t work because it runs at random times and only once per 10 minutes at its most frequent.

Running on Cedar. Running multiple web dynos.

EDIT: Here’s what I want to do:
Call an arbitrary method with params at an arbitrary point in the future. Something like Schedule.set(Notification.send_update_to_user(574), Time.now + 1.days)

Answer 1

After looking at different options, I chose Delayed Job, which is well documented on Heroku.

For jobs that need to run at a certain time each day or once an hour, Heroku scheduler works well, but sometimes it doesn’t run.
