Sergey Shelukhin commented on HIVE-5588:
----------------------------------------
I've read a bunch of code today and I think I have an idea of what needs to be
done.
One thing that is not good in this case is that getting key out of the row will
have to be done by both TopN and ReduceSink separately when ReduceSink is used.
> change TopN to be an operator

> If topN is a separate operator, it can be reused for file sink, and
> vectorized version can be implemented.
