Cool stuff.

I read the blog and my understanding is that streamlit will handle dataframes into arrow dataframes internally. Am I right?

I even tried using pyarrow inside a streamlit app, but it throughs me out.

Nice!

Hey @oltipreka !

Yep, you’re correct the conversion is done internally. :balloon:

Regarding pyarrow, would you mind making a post under Using Streamlit - Streamlit with a your code so we can take a closer look?

Thanks!
