   > I am sorry I have not been following along this PR closely -- is it ready 
for a final review @chenkovsky and @adriangb ?
   
   @alamb The discussion was very lively. 
   
   from my opinion, the pros of this PR are: dataframe api friendly, spark 
compatible, no need to worry about metadata/system column leakage. for #14362, 
it makes an assumption on project plan which is not correct for dataframe api, 
and it should check schema of user input file, otherwise the magic metadata 
dict will be loaded from file. and it should pay more attention to prevent 
metadata/system column leakage. in this PR, there are no such problems. In part 
I agree with @adriangb, If I have another choice, I won't use offset. But I 
think there is no better option.
   
   we also want to hear your opinions.
