Loading data into Titan

Question

I am currently running Titan Server (0.4) [via bin/titan.sh -c cassandra-es start] and load the sample data using rexster-console:

rexster[groovy]> g = rexster.getGraph("graph")
rexster[groovy]> GraphOfTheGodsFactory.load(g)

How can I do the same thing above using a RexsterClient in java? Essentially, Is it possible to get access to graph without me having to embed all this in client.execute()?

Thanks for your help.

Answer 1

Once you've created the graph you can access it with RexsterClient. You shouldn't need to recreate the graph again with it as the data is already in Cassandra. Just specify the graph name when constructing your RexsterClient instance (in the case of Titan Server the graph name is just "graph"):

RexsterClient client = RexsterClientFactory.open("localhost", "graph");
List<Map<String, Object>> results = client.execute("g.v(4).map");

That will initialize "g" and allow you to just issue some Gremlin against the Graph of the Gods sample data set. You can read more about the options for RexsterClient here.
