   > FYI @suremarc @berkaysynnada / @ozankabak as this changes statistics and I 
think you are already working on things related to that:
   
   We've started to refactor. The design is complete, and the implementation is 
in progress.
   
   I’ve taken a look at this and have some questions. For example, are we 
planning to add many types of functions to statistics, or is there a defined 
list of statistics that can be inferred from the sources or have meaningful 
applications in optimizer rules? If we agree that these kinds of extensions to 
column statistics are indeed useful and obtainable, then we can proceed with 
merging this. We would also ensure it is included in the new setup.
