Performance: Websocket: Client -> Server: Big size, causes excecution / reruns to slow down

[robingie]

I noticed, that the binary message sizes through the web socket massively increase when displaying more than 500 rows. Once the grid result is loaded and rendered, it's pushed through the web socket with every rerun.

Unfortunately, that causes laggy reruns due to size when working with a slower connection or higher latency. Placing widgets under the grid doesn't work well because the execution sometimes stops.

Is there a way to reduce the transmitted size and transmit only the delta changes like Streamlit is already doing natively with their st.dataframe / st.data_editor widget?
