Blog post: Converting CSV to parquet in Clojure

Following some conversations we had at the conj we wrote a short article about using Clojure to convert CSV into parquet files.

hth - keep the good questions coming!

You’re welcome.

And indeed, this is just a small moment in a much larger undertaking of trying to understand “functional data science”.

Thanks for looking into it.
