I had a play with getting a minimalist apache (v1) arrow & parquet to compile to wasm32-unknown-unknown back in July/August (2021) when the released version of arrow was ~5.0. It worked ok, I vaguely remember having to do something around adding an annotation on the hashcode for one of the structs to point rustc at an implementation that worked in wasm (I'm very new to Rust and definitely still in the "muddling through" phase"). My tinkering has been on the "back burner" since September (for a number of reasons, not least the hard disk on my personal laptop dying), I got chance over the Christmas break just gone to recover what I can from the dead disk and get started again :) The apache arrow-rs v6.5.0 crate builds without any modifications :) I've put the (very basic) results of my tinkering into a [git repo](https://github.com/my-liminal-space/read-parquet-browser). Its based on the "Rust and Webassembly" example project, uses the parquet crate to read a parquet file and the javascript arrow library to read values out of the result. I recently stumbled across a reference to the arrow2/parquet2 projects, the design goals seem sensible but I haven't had chance to look at them yet. -- This is an automated message from the Apache Git Service.
