@sdf-jkl could you help me with some napkin math on how this optimization works? Is the idea that applying a row selection when a page index is present is more efficient? I'm not sure if that means we should filter columns that have a page index first or last, and how that would weigh against e.g. the size of the column or the selectivity of the filter 🤔 -- This is an automated message from the Apache Git Service.
