Sergey Shelukhin commented on ORC-243:
--------------------------------------
Actually, TreeReader-s need to create valid vectors, so they do need to know
about every flag - either explicitly, or by unobvious assumptions, as
illustrated by (2). Nothing needs to be reset.
Yeah, the usage of correct vectors implies not looking at isNull when noNulls
is set which is acceptable... we won't need noNulls flag if we were checking
isNulls every time ;)
> incorrect isRepeating handling in decimal reader
