GitHub user pepijnve added a comment to the discussion: Multiple 'group by's, one scan
Just FYI, in the particular case I'm working on the problem I'm dealing with is that I want to compute a whole bunch of aggregates over a table with a cardinality in the billions order or magnitude. For `n` aggregations I'm trying to reduce the time spent on table scan from `n * s` to `s` because `s` is pretty significant.
