DataFrame.IO.Parquet — pure-Haskell Parquet 2.0 reader and writer (with snappy, zstd, gzip codecs, dictionary decoding, nested list/repeated columns, predicate pushdown, and HTTP range reads). Heavy package — pulls in pinch, streamly, compression codecs, and http-conduit. Most users want dataframe-csv instead unless they specifically need Parquet.
