@ramitg254 please take a look: 9e7535c. I would suggest following similar approach

[ramitg254]

9e7535c

but here we are creating separate method getEffectivePartCols() and leaving getPartCols() as it is, which as per our discussion on that closed pr we shouldn't do that, and only go ahead with updating getPartCols()

Where did I say that? The ask was to keep the original method unchanged. same here

[ramitg254]

oh I got confused due to this comment: #6337 (comment) in which getSupportedPartCols() was just separate method similar to getEffectivePartCols()

[ramitg254]

I am fine with that earlier approach as well but recently I saw this one: https://issues.apache.org/jira/browse/HIVE-29525 so I thought we should have unified getPartCols() and getCols() which gives similar results as native hive tables as first step towards solving this after that those plan logics can be taken care of later on when that ticket will be addressed.
So I was first focussing on making getPartCols() unified for iceberg tables as well.

please share your thoughts on this idea
