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. > [JS] Arrow Flight JavaScript Client or Example > ---------------------------------------------- > > 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.? -- This message was sent by Atlassian Jira (v8.3.4#803005)
