You could. However, I would only do this if you need tasks ran on all of the web servers. The two should not conflict with each other.
sidekiq-cron is a separate, third-party addon for sidekiq. It does not require Pro/Enterprise. My reference in the video was meant to say that without this gem (or another third-party), and to still have the periodic task functionality, you would have to use Pro/Enterprise.
I do plan on doing some testing. However, I think week after next, I'll be focusing on searchkick/elasticsearch.
I've updated the episode with the schedule.yml file. That was definitely an oversight, so thank you.
I don't think that sidekiq-pro offers recurring jobs.
For terminology sake, a scheduled job would be the result of an action telling the background processor to schedule the job for a later time. For example, if a new user signs up for your application, you can set a scheduled job to thank the user for signing up and give some tips about your application 24 hours after they sign up.
A recurring job or periodic task, would be something where you are wanting to perform a task every x intervals. For example, if you have a ToDo list application and you want to send a notification to your users every morning with an overview of what they still need to do or have completed the previous day, sidekiq-cron would be a good fit for the job.
You should be able to use sidekiq-cron along side sidekiq-pro. However, if you're using sidekiq-enterprise, there is no need for sidekiq-cron since this functionality is built into sidekiq-enterprise.
Thanks! Sounds good to me!
