Research direction

Start by locating the SDF.groupby() implementation and the existing sum, mean, std, and var aggregation paths. Compare how those operations are supported, then determine the scope needed for min() and max(); done means grouped stream data supports both operations consistently with the existing aggregations.

Written by the indexing model from the issue text.

Description

I'm curious as to why sdf.groupby([.., ..]).min()/max() aren't supported. I see that sum, mean, std, var, etc. are. Any complexity of the issue I might be missing?
