Review Comment:
   Thanks @gaogaotiantian, and that makes sense to me.  I agree that the 
annotation should match the runtime behavior, and it would be confusing to 
accept a tuple of columns on some of these APIs but not others. 
   
   @HyukjinKwon, does this address your concern, or do you still see a downside 
to supporting it? Happy to go with whatever you two prefer.
