Xuefu Zhang commented on HIVE-4844:
-----------------------------------
[~jdere] Thanks for sharing your work. I went thru your patch and had some
initial questions. I understand that your patch is still in progress, but I'm
wondering what's your thought on how you plan to store the type params.
Obviously, type params are metadata of a column, which needs to be stored. I
assume that hive schema needs to change to accommodate this.
Secondly, SQL VAR or VARCHAR seems to be special hive string with additional
restriction. Your patch seems treating them independently. Do you think if type
inheritance works here?
Lastly, introducing param types seems non-trivial. Do you think if a design doc
or wiki page makes sense?
