David Li commented on ARROW-9860:
---------------------------------
Hey [~Hugheym] it's mostly a question of effort, and approach (grpc-web, one of
the gRPC proxies, a whole native REST-based implementation?) Also the various
gRPC-in-the-browser implementations don't support bidirectional streaming - so
we'd need to figure out what to do with DoPut and DoExchange. Finally I think
the JS Arrow library has lagged behind a bit and so some work is needed there
too (e.g. the 1.0.0 format changes).
All in all, I think it's feasible, but needs someone to drive it. I'm happy to
answer questions about Flight and help with the effort as I have been
interested, but never had the time to drive this by myself.

> Project: Apache Arrow
> Issue Type: Wish
> Components: JavaScript, Python
> Reporter: Alex Monahan
> Priority: Major
>
> Is it possible to use Apache Arrow Flight to send data from a Python Web
> Server to a JavaScript browser client? If it is possible, is there a code
> example to use to get started?
>
> If this is not possible, what is the fastest way to send data from a Python
> Web Server to Apache Arrow in the browser today? Would it be faster to send a
> Parquet file and unpack it client-side, or send Arrow directly/with gzip/
> etc.?
