             Summary: [JS] Implement C Data Interface
                 Key: ARROW-17608
                 URL: https://issues.apache.org/jira/browse/ARROW-17608
             Project: Apache Arrow
          Issue Type: New Feature
          Components: JavaScript
            Reporter: Kyle Barron


I've recently been working on an implementation of the C Data Interface for 
Arrow JS, the idea being that Arrow JS can read memory from WebAssembly this 
way without a copy ([blog 
post|https://observablehq.com/@kylebarron/zero-copy-apache-arrow-with-webassembly],
 [repo|https://github.com/kylebarron/arrow-js-ffi/pull/11]). Dominik 
[suggested|https://twitter.com/domoritz/status/1562670919469842432?s=20&t=Ts8HQe_fzgRmecUP1Qrhrw]
 starting a discussion about potentially adding this into Arrow JS.

My implementation is still WIP but figure it's not too early to start a 
discussion. A couple notes:

- I'm focused only on reading FFI memory, so I only have parsing code. I figure 
writing doesn't really make sense in JS since Wasm can't access arbitrary JS 
memory
- In order to generate FFI memory in the tests, I'm using a small Rust module 
to convert from an IPC table. If we didn't want to add a rust build step in the 
tests, that module could be published to NPM

Thoughts?
