How Can I make a statistics,i.e:how many vertexes or edges?
My graph has about 100 million vertexes and 200 million edges. But if use the following code, it is too slow.
GraphTraversal<Vertex, Long> countV = traversal.V().count();while (countV.hasNext()){

Re: [BLOG] Configuring JanusGraph for spark-yarn
Hi John,
Your assumption about different types of graph object for OLTP and OLAP is right (at least for JanusGraph, TinkerGraph supports both). I remember examples from the gremlin user list, though,

HadoopMarc,
It seems that we have two graph classes that need to be created:
The first is a standardjanusgraph object that runs a standard computer. This is able to perform OLTP data pushes and, I

Re: JanusGraph support for Cassandra 3.x
Interesting, if you have a record of what your issues were, could you create a ticket? I haven't seen issues with Cassandra 3.10
and the Astyanax adapter but maybe your setup or usage patterns were

Re: keyspaces in JanusGraph
Hey Peter; as Ted said you can define which keyspace you connect to using the appropriate configuration property when defining your graph's .properties file.

Re: How can I tell if indices are being used in a query (intercepting the log)
The only way I found was to step through the code. While stepping, I didn't see any logs that were there to be missed.
What we really want is for this to be part of the output of the explain step
