Another way of doing it is to create a file format that contains index along
with data... but i think that would take lot more time.

We are trying to store data in sorted and block-indexed files (such as HFile or
TFile). Then I think we can know the startKey and lastKey of each file and each
block. This block index(block summary) is just for primary key.
