Paul Taylor commented on ARROW-9860:
------------------------------------
JS does not support buffer-level compression, and possibly shouldn't ever, due
to the significant drawbacks of adding JS or WASM-based compression
implementations to the browser bundles such as perf hit in the readers/writers,
significant addition to library size, etc.
The only widely/natively supported deflate implementation in browsers is gzip
(and to a lesser extent, brotli), but deflate is applied at the message/chunk
level in the browser's networking stack, so compression must be applied to the
entire payload.

> Key: ARROW-9860
> URL: https://issues.apache.org/jira/browse/ARROW-9860
> 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.?
