   @andygrove FYI this was the 2 line implementation I mentioned ;).
   
   I think there are some nice improvements already with this very simple change - but most of the larger potential improvements for some queries might come from avoiding shuffle / IO.
   
   I'm not sure if we should merge it as is or it might serve as a PoC.
   
   At least I am very interested if this also improves performance at larger scale factors.
