Ok, this makes sense to me, but had a few more questions to make sure I fully understand. What happens if a user enables Null Support on an existing table but does not configure any columns? If a table has a mixed state where some segments were generating their Null Value Vectors and older segments did not have any configuration for what columns were nullable, then what happens if a user runs a query with `IS [NOT] NULL`? My primary concern here is that, currently, if someone enables Null Support on an existing table then `IS [NOT] NULL` queries will return invalid results from the segments that don't have Null Value vectors; and I'm not sure that this solution will solve that problem. -- This is an automated message from the Apache Git Service.
