Writing Parquet files using Haskell

Looks like a pretty cool community building great tools with care. Using a functional language for data transforms sounds like a sane idea, haven't played around with it yet but it's definitely on my list now.

However they claim using Haskell for data science is "fast", which doesn't really mean anything until you have numbers to show. A little benchmark with pandas and polars wouldn't hurt I guess.

I'd personally rather see Haskell become part of the options for https://arrow.apache.org/, but this is still a cool project.
