Review Comment:
The "Num rows" is calculated estimate by dividing data size by average row
size.
Previously data size was 13,710 and now it is 13,720.
Average row size = 196
Before Orc upgrade it was: 13,710 / 196 = 69.??? - hence the value of "Num
rows" was 69.
Now: 13720 / 196 = 70
So basically the reason for num rows change is that Data size value
increased.
