Dynamically update periodic tasks in Celery and Django
I was looking for a nice way to manipulate periodic tasks in Celery. I found an amazing django-celery-beat package that provides PeriodicTask database objects. With PeriodicTask objects, you can dynamically add/remove/update periodic tasks in Celery. I want to share my approach. I've created an example GitHub repository and wrote step-by-step article.

That's pretty cool. Reckon it would work with existing code that calls Redis over the wire for RQ?

Keep the Monolith, but Split the Workloads
We use RQ[0], it has Redis as a dependency. It’s pretty straightforward and we’re very happy with it. If you are using Django you may want to look at Django RQ[1] as well. RQ has built in scheduling capabilities these days, but historically it did not so we used (and still use) RQ Scheduler[2] which I think still has some advantages over the built in stuff.

SQL Maxis: Why We Ditched RabbitMQ and Replaced It with a Postgres Queue
Also had a similar experience using RabbitMQ with Django+Celery. Extremely complicated and workers/queues would just stop for no reason.
Moved to Python-RQ [1] + Redis and been rock solid for years now.

Recommendations other than celery to send an API processing in background, which would only take 5 mins to process and API usage would be once a month or so.
Yep, rq is simple and good: https://python-rq.org/ It also has a Django wrapper: https://github.com/rq/django-rq
