titan Getting started with titan Initialising a Titan Graph

Example

With the appropriate storage backend running a new titan graph can be initialised via:

graph = TitanFactory.open("config.properties");

Wehere config.properties defines several configurations relevant to the storage backend. Titan provides some sample configs in its downloadable package. For example conf/titan-cassandra.properties

A shorthand can also be used when you want to ignore most configuration options:

For example for a Cassandra backend:

graph = TitanFactory.open("cassandra:localhost")

For a Berkeley DB backend:

graph = TitanFactory.open('berkeleyje:/tmp/graph')

All the above commands will create a Titan Graph which persists the relevant backend. If this is the first time executing these commands the graph will initially be empty.
