Whenever VS sidekiq-scheduler

Learn about Unix cron and use the whenever gem.

there are cronjob gems available, i believe https://github.com/javan/whenever or so seems to be used frequently

- Use them on a specific schedule as needed by your application, such as taking backups, sending periodic reminders or notifications for users, cleaning the database tables, etc. You can use a gem such as Whenever for managing scheduled cron jobs.

whenever gem is used in Rails applications to schedule cron jobs e.g. send email notification about monthly expenditure on the 1st of each month.

Then you can use the whenever gem to schedule stuff.

whenever

There are multiple ways to achieve this. Probably the simplest and most reliable is to rely on cron to run your process every minute. Cron keeps track of time and executes your script each minute. This has the added benefit of avoiding a long running process (which can have its own issues). You can even have your script install it’s own cron job using the Whenever gem.

Rake tasks can be called from Cron, so we'll use the Whenever Gem to automatically add our job to our Crontab during deployment, and keep our schedule in change control.

I've used sidekiq-scheduler, since I've already had sidekiq as my background job processor. But any cron scheduler will do.

I run this as a cronjob via https://github.com/moove-it/sidekiq-scheduler

This gem is no longer maintained and has compatibility issues with newer Redis gem versions. I'd recommend https://github.com/moove-it/sidekiq-scheduler.

Any reason to not use Sidekiq to set up a scheduled recurring job? I've got applications that use Sidekiq Scheduler to handle similar enough use cases (fetching data from a remote source), and it seems perfectly fine.

Maybe with sidekiq-scheduler

https://github.com/moove-it/sidekiq-scheduler is an extension which you can use with free sidekiq.
