   >  However, I didn't think about much about generating of such dataset. My 
rationale was that this feature is possible, and if a use case arises, not 
supporting this feature is counter-intuitive on the user side.
   
   I think it could arise with functional dependencies (e.g. if we had a column 
like `quantity` and `rounded_quatity` and where there is a function like 
`f(quantity) = rounded_quantity` that preserves the ordering of `quantity` 🤔 
   
   DataFusion does not have this kind of analysis yet  but I could imagine it 
happening
