I'm trying to build a Podcast Listener,and want to check with Celery Cron Periodic Tasks when a new episode is Published.

I want to have the ability to add new Periodic Tasks with REST API, not jut from the go when u create the app.

My Question is what happens when redis server goes down, or i want a bigger redis server to handle more tasks ? From my understanding the tasks i created with REST API will be lost, only tasks that i created on the go will still be available.

I was using celery-sqlalchemy-scheduler but the library is not supported anymore, and has issues with postgress.

What should i do, should i save all tasks i create with redbeat in a database, and every time i restart redis or get bigger server i need check all tasks in postgress database and see if the exists in redis and created if does not exists ?

@thisiseddy-ab - would you still be interested if https://github.com/AngelLiang/celery-sqlalchemy-scheduler was forked and supported?

Either you need to use one of the HA/cluster redis modes, have a way to re-hydrate the tasks or trust the redis persistence
