Comment:
Add the difference between S2Graph and Giraph

  
  == Rationale ==
  Graph data(highly interconnected data) is very abundant and important these days.
- When user have a multitude of relationships, each with complex properties associated with
them, graph model is more intuitive and efficient than tabular format(RDBMS).

  There are many ASF projects that provide SQL layer, but there is no ASF projects that provide
scalable graph layer on existing hadoop echo system.
  When graph data grows to trillion edge scale, the process of traversing takes a long time
and costly. However, with the benefit of HBase`s scalable architecture, S2Graph can traverse
large graph in breadth first search manner efficiently.

  === Relationships with Other Apache Products ===
  S2Graph has a strong relationship and dependency with Apache Hadoop HBase and Spark. 
  Being part of Apache’s Incubation community, could help with a closer collaboration among
these two projects and as well as others.

+ In terms of graph processing frameworks, S2Graph and Apache Giraph look similar. However,
their goals are apparently different to each other. Giraph aims at analytical batch processing
on immutable graph data sets. In contrast, S2Graph is designed for OLTP-like workloads on
graph data sets, and S2Graph provides INSERT/UPDATE operations too.
  
  
  === An Excessive Fascination with the Apache Brand ===
