I heard that there is an attempt to develop arrow for shape files to generate maps. How is that coming along?

I am running a M1 Mac and getting errors even though the arrow package is installed. The message is: Error: This build of the arrow package does not support Datasets

I have a file from the Collegeboard (scorecard) that is 566 MB as a csv on my hard drive. However, the parquet file of the same data only takes up 54 MB. Seems incredible.
