I am looking for the best way to run a very long task in Heroku.
I use Ruby On Rails for my web application and I have a very long task that I want to run it every week on Sunday during the night. It takes around 15~20 minutes. I already have Rufus-Scheduler, but I am not sure it is the most effective solution.
I also find something about Backgrounding Tasks in Heroku with Delayed Job. But is it the best way to handle it ?
Thanks.

So, the reason why you cannot use SQLite on Heroku is because SQLite stores all database information in a file on disk, and because Heroku will delete the files on your disk, this won't work.
Cron To Go is an add-on created for Heroku users to run scheduled jobs based on one-off dynos using cron expressions. Cron To Go combines the simplicity of using cron to schedule jobs with the scale and elasticity of the cloud.
Ruby on Rails is a popular web framework written in Ruby. This guide covers using Rails 7 on Heroku. For information on running previous versions of Rails on Heroku, see the tutorial for Rails 6. x or Rails 5.
This is what I use for a job that I run every night: https://devcenter.heroku.com/articles/scheduler
It works really well if your job is configured as a rake task. The guide at the link shows you how to configure everything and even addresses long-running jobs.
