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.
