> On optimizer side, I am not sure if `single_distinct_to_groupby` can really improve performance in current version (it is an old rule introduced in long long ago), maybe we can check it again?
On my m1 mac 16g, removing it shows no differences (and even a little faster overall). So i think we can maybe remove it?
