🤔 I see -- I can imagine the ranges being an over estimate (being at least as large as the actual range). I wonder how an "overestimate" would apply to num_rows. Unless we knew the distribution exactly, in order to preserve an overestimate in num_rows, wouldn't we have to assume no rows were filtered ? -- This is an automated message from the Apache Git Service.
