Re: Management command scheduling options

[Ahmedrufai Otuoze]

Hi Mike,

I've implemented something similar to what you mentioned lately. I used
this Python package called APScheduler to schedule and run database
intensive queries behind the scene and then cache the result for my users
to fetch from making their experience super fast.

The APScheduler can be configured to run at any interval daily, weekly,
monthly or any customized interval you require. It's a game changer and a
quick win for Windows based OS as they don't support the use of Celery or
any other Linux based schedulers without WSL.

Do let me know if you're interested in my implementation, I'm open to show
you.

Regards

This is not a spam. I just tok a course on that aspect and wanted to help.
No strings attached.

I may have gone against the policy and that's because I wasn't aware.
My intentions were genuine...

Hi Mike,

I can help you solve the problems.
I can clone it from your repo and we'll work on it...

What do you think?
