"It is not 100% clear to me how a new file format (or three) will drive additional ecosystem adoption :thinking:"

However, I absolutely think this adds to the pressure for Parquet to evolve.

Speaking of, anyone interested in helping add new encodings to parquet?

Sorry to hear that! That would be the one mistake that Parquet didn't make.
I'm hoping to help the ecosystem converge.
Thank you for the great contributions.
