   > How do you plan to maintain this endpoint?
   > Not sure if this can help with query push down as the behavior must be identical on presto side and pinot side. IMO it is safer to manually select functions to push down instead of using name matching. It can cause unexpected behavior if the behavior is not exactly the same.
   
   We can use reflection to auto generate this information or we can get it from TransformFunctionFactory. 
   I think this is useful when we have many releases of Pinot and Presto and we are keep adding new functions.
