Wondering is Apache Parquet would compare well.
I’m unsure of the quality of parquet implementations for browsers [0], though.

3 points · Open discussionShow HN: Hyparquet 1.0 – Apache Parquet Parser for the Browser
I started 6 months ago when I wanted to look inside datasets from Hugging Face. I was not satisfied with existing libraries. So, naturally, I built my own library from scratch.
Parquet is a very complicated format. It has 22 data types, 9 encodings, 8 compression codecs. Previous parquet js libraries went abandoned due to the complexity. However, I can confidently say that Hyparquet is now the most conformant parquet parser in existence. It can open more files than PyArrow and DuckDB. I dare you to find a file that Hyparquet can’t open!
In addition to supporting all the parquet files, Hyparquet supports efficient streaming of parquet data over the network, even cross-domain using CORS. This means you can stream files straight from S3 with no backend.
Hyparquet is open-source MIT licensed.
