Hello,

I am looking at todo item /Implement DISTINCT clause in window 
aggregates /and while looking at code, I found /distinct/ tightly 
coupled with Agg function. Looking at another todo item/Do we really 
need so much duplicated code between Agg and WindowAgg?/  I was 
wondering what is general stance on this?

If Agg/WindowAgg gets harmonized, implementing distinct would be lot 
more intuitive. Should this be attempted first? If this is not 
necessary, I assume making distinct a standalone piece should be an 
option too?

Thanks,

Ankit
