Agreed, really need a tl;dr here, because Parquet is boring technology. Going to require quite the sales pitch to move. At minimum, I assume it will be years before I could expect native integration in pandas/polars/etc which would make it low effort enough to consider.

Parquet is ..fine, I guess. It is good enough. Why invoke churn? Sell me on the vision.

DuckDB just added support for vortex in their last release using the Vortex Python package so hopefully other tools wont be too far behind

Mutability would be one such pitch I would like to see ...
