This seems to be quite a good situation to use polars. I have also been using polars, instead of numpy and it has been a game changer.

I have to say, this is one of the most detailed blogs I have read in a couple of months. Kudos to you!

Thank you for your comment! I'm glad you found my article inspiring.

I'm glad to hear that you've had a positive experience with it. What specific features do you find most useful?

Did you add uvicorn to requirements.txt? https://blog.akashrchandran.in/deploying-fastapi-application-to-render#heading-creating-requirementstxt

Great share, I am going to use it from now on.
