I'm trying to write a Janus DB loader for my distributed application.
I have "sub-graphs" which I can successfully load independently, per machine in my cluster. I do this by using graph.addVertex and subsequently a loop of vertex.addEdge(otherVertex), for each vertex in my sub-graph.
However, I have a second kind of vertex, whose edges can refer to any other vertex on any other machine. These effectively join my sub-graphs together.
JanusGraphVertices are not serializable, so i cant transport the vertices across machines. Also I can't seem to find a nice way to fetch these vertices from Janus, from the already loaded sub-graphs. Is there any way to do this nicely?
I know I could probably write the entire graph out to HDFS and load to Janus with a bulk loader program. However my application doesn't currently require Hadoop and i'd like to avoid this if possible!
