Setting up Titan to use the Cassandra storage backend

We've seen that Titan supports different storage backends. Exploring all three options is beyond the scope of this chapter (you can learn more about Titan and its configuration options at http://thinkaurelius.github.io/titan/), so we will focus on using the Cassandra (http://cassandra.apache.org) storage backend.
