At this very moment, specifying different compression algorithms per column is supported and in my use case it is extremely helpful, as I have some columns (mostly containing floats), for which a compression algorithm like Snappy (or even no compression at all), significantly speeds up my queries than keeping the data compressed with something like ZSTD or GZIP.
Ok, but you are still not explaining why you would like a different compression algorithm *per row group*, rather than per column.
