RJ Atwal commented on ARROW-9453:
---------------------------------
[~andygrove] To answer your questions:
1. Wasm code would be running in the same process as Spark (unfortunately their
will be a JNI wall between the two execution areas though).
2. I want to use arrow as the format to pass data (references) between Java
land and the WASM (native) execution. So, I need libraries to handle arrow on
both environments.
> [Rust] Compiling Rust libary against WASM32 library
> ---------------------------------------------------
>
> Key: ARROW-9453
> URL: https://issues.apache.org/jira/browse/ARROW-9453
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust, Rust - DataFusion
> Affects Versions: 1.0.0
> Reporter: RJ Atwal
> Priority: Major
>
> I am hoping to support arch_target=Wasm32 as a compilation target for the
> rust arrow & datafusion packages.
> My plan is to add compiler conditionals around any I/O features and libc
> dependent features of these two libraries.
> My intent is to be able to use the apache arrow libraries in UDF style WASM
> functions which pass arrow memory references between the host (spark
> environment) and the WASM code
