Review Comment:
> If index is used, is there such case that we read page number 10 first and
then read page number 1? Or in other words, could we make sure that the data
page is read in descending order?
@yiguolei Yes, we are sure the data page is read in ascending order: after
locating the first target page, we will read the following pages sequentially,
for a single query of course.
