hi Tommy,
The project has to release first. You can have a look at the 0.4.0
milestone here
https://issues.apache.org/jira/projects/ARROW/versions/12342901

Hey team,
I noticed the package at https://www.npmjs.com/package/apache-arrow is 8
months old and lists version 0.3.1. The code lists v0.3.0 in packages.json.
Can we get a new package published to npm? It would also be good to clarify
the versioning story before we do it.
Thanks!
Tommy Guy

I'm curious how the file is only 100MB if it's producing ~6GB of
strings in memory. Is it compressed?

Thanks,
I've tried the new code and that seems to have shaved about 1GB of memory
off, so the heap is about 8.84GB now, here is the updated pprof output

Could you explain why having a separate crate would be a good idea?

separate crate for the format/ipc generated code. I think there might be
some merit in this and wanted to raise it here to see what everyone thinks.
This would mean having two directories under the rust directory ... one for
