> To support replacing window first/last, there are many issues to be solved. I wonder if starting with simpler aggregates (like `approx_distinct`) might be a good idea. They are probably simpler to port and would let us work through some of the details before breaking off the larger more complex ones `first_value` / `last_value` are likely the most complex as they are order aware and can be used as aggregates and window functions -- This is an automated message from the Apache Git Service.
