使用Ruby On Rails在Heroku上运行长任务的最佳方法是什么？

Question

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.

Answer 1

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.

Answer 2

Heroku does not recommend to run long-running jobs with Heroku Scheduler.

Heroku says,

Scheduled jobs are meant to execute short running tasks or enqueue longer running tasks into a background job queue. Anything that takes longer than a couple of minutes to complete should use a worker dyno to run.

So, in my opinion, the best approach would be to use Heroku Scheduler to run rake task for every kind of job (short or long) but if a task takes longer than a couple of minutes then I would simply create a Background Job within that rake task. That way the scheduler will never run longer than a couple of minutes.
