how to locate the location of block in the Stream Layer for the row of Windows azure storage table?

Question

According to the following paper "Windows Azure Storage: A Highly Available Cloud Storage Service with Strong Consistency", the block is the minimum unit of data for writing and reading ,that is to say,if I want to read a row, we must need to locate the location of block in the Stream Layer.

So I think the steps to locate the location of block are:

1 get the block number/extent offset Based on the row

2 use that block number/extent offset getting from step1 to locate the block in the extent in the Stream Layer

So my questions are:

1 how to get the block number/extent offset Based on the row?

2how to use that block number/extent offset to locate the block in the extent in the Stream Layer?

Are there any map for row to block number/extent offset and map for block number/extent offset to location of block in Partition Layer.?

I just cannot find those information in that paper.
