I'm trying to figure out if it is possible to create graphs on the server from a java/scala client but I haven't found any examples.

I'm running janusgraph 0.3.1 configured with the configurationManagementGraph with cassandra and solr. The server seems to run correctly.

But I can't figure out how to create a graph from my scala client on the server.

Is this supported? What is the usual way of creating graphs in janusgraph?

This is what works for me in Java

GryoMapper.Builder mapperBuilder = 
GryoMapper.build().addRegistry(JanusGraphIoRegistry.getInstance());
MessageSerializer serializer = new GryoMessageSerializerV3d0(mapperBuilder);

Cluster.Builder clusterBuilder = Cluster.build();
clusterBuilder.addContactPoint("localhost");
clusterBuilder.port(8182);
clusterBuilder.maxContentLength(524288);
clusterBuilder.serializer(serializer);
Cluster cluster = clusterBuilder.create();

try {

    GraphTraversalSource g = EmptyGraph.instance().traversal().withBulk(true)
        .withRemote(DriverRemoteConnection.using(cluster));

    ...

} finally {
    cluster.close();
}

  • by this we wont able to create/open/drop graphs. Your code can be used to get GraphTraversal after a graph is created. The original question was about creating a graph from client (java). – anaray Jul 24 '20 at 19:36
