You'd better make sure that that function isn't pushed down.

I thought it would not be pushed through the GroupBy clause. Then, do you think
it is better to formulate it in the translation to Calcite as
grouping_id(e1,...) instead of group_id()? Then, as it is dependent on the
other columns, it will not go down for sure.
