Hequn Cheng commented on FLINK-18763:
-------------------------------------

Sure, a well-defined set of types makes sense to me. We can provide a minimized 
set of types at the first step and add more ones once we truly need it. As for 
{{DATE_TYPE_INFO}} or {{VOID_TYPE_INFO}}, I think we don't need them for now. 

Thanks a lot for your inputs here. [~twalthr]
