The goal of this fork (at the moment) is to implement a proper embedded cassandra backend for Titan.

Quick review

Pros

No Thrift connection : no network timeout (at least not from Thrift), no (de)serialisation overhead, no memory used for connection buffers ...
Bundle your components in a single JVM and avoid memory overhead (Java...)

Cons

Runs in the same JVM as your Cassandra
If you want to update your Titan codebase, you have to shut down a Cassandra node (which can be pretty slow for a production environment)
Needs more testing ! :) (Still, I'm using on a daily basis and it's quickly improving)

Usage / Misc

You have to start CassandraDaemon etc. outside Titan on your own (since embedded is usually for specific uses, I decided to make the driver dependent on a pre-started Cassandra instance, same JVM)
I have been using it with success to load and analyse medium-sized graphs (1.2M nodes / 15M edges)
