Streamlit cannot display large dataframes; should at least show something useful to user about this.
See original GitHub issueCannot display large pandas dataframes.
User example:
Occasionally I would do something stupid like st.write(df) only to get this error.
EXCEPTION! Message ForwardMsg exceeds maximum protobuf size of 2GB: 3085985846 The reason - trying to display a DataFrame with millions of rows. ```
Solution
MVP: Clarify what the limits are. Are there limits to number of rows? File size?
User suggestion:
It would be better to detect this and just do df.head() internally and show a warning. At least this would not crash the streamlit process and bust the cache.
Preferred solution: No upper limits (besides what fits into RAM).

@qutang Just circling back to say we have an improvement just merged into the development branch that should allow nearly any size of video (or audio or image) to work on Streamlit! Hopefully it’ll be packed with the next release. Thanks for your patience.
Leaving this open since @kantuni is still working on the Dataframe aspects.
