The GraphFactory interface we defined earlier creates a TinkerPop Graph implementation, where a Map object represents a Storm configuration. The following code illustrates how to create TitanGraph backed by Cassandra:
TitanGraphFactory.java
public class TitanGraphFactory implements GraphFactory {
public static final String STORAGE_BACKEND = "titan.storage.backend";
public static final String STORAGE_HOSTNAME = "titan.storage.hostname";
public Graph makeGraph(Map conf) {
Configuration graphConf = new BaseConfiguration();
graphConf.setProperty("storage.backend", conf.get(STORAGE_BACKEND));
graphConf.setProperty("storage.hostname", conf.get(STORAGE_HOSTNAME));
return TitanFactory.open(graphConf);
}
}
