A similar message came up on the gremlin-users mailing list. You might want to compare notes with that thread. https://groups.google.com/d/msg/gremlin-users/LYv-cvZ66hU/vqZJD4OzBQAJ

No, it is not a bug. It is a warning letting you know that there is a query that is doing a global scan of all vertices. In this case, the specific call is `g.V().count().next()` which is trying to

Hello! I get the example : https://github.com/pluradj/janusgraph-java-example Why is there a warning in the log? "WARN org.janusgraph.graphdb.transaction.StandardJanusGraphTx - Query requires

Hello, I'm attempting to transition from Titan to JanusGraph 0.1.0 and am having problems getting OLAP queries to work via Spark. I've loaded a graph with about 2 million vertices and tried to

I went ahead and did this https://github.com/JanusGraph/janusgraph/issues/272

Thanks for the feedback, John. Issues with the code and documentation are tracked on the project's GitHub issues https://github.com/JanusGraph/janusgraph/issues Please go ahead and open up an issue

Hello, I read through the docs and found various flaws. Some were key concepts not congruent with the codeblock and some were various typos. And since there is no link to report them, I thought I'd

Hi Joseph, Sounds like OLAP is not going to help you here (you would need a gremlin database query step or a customer vertexprogram), You need a JanusGraph index on a unique property of your vertices.

Hi Marc - thank you for the reply. I've written java code to take some data and use it to generate a graph. After that data is put into JanusGraph, I then loop over all the nodes (in the

Hi Joseph, If you want to process all vertices (map operation) you need an OLAP query (currently only works for readonly

I think you're looking for janusgraph-core/pom.xml. All of these dependencies end up in the distribution zip.

Hi All - I'm using a loop to do a task on all vertices in fairly large graph (million+ nodes), and the operation that I'm doing takes some time. I'm getting a

Hi Folks, Forgive me for the simple question, but I've got: # git clone https://github.com/JanusGraph/janusgraph.git # mvn clean install -DskipTests This all works fine. But I want to add a new JAR to

Answering my own question, BulkLoaderVertexProgram uses a nested instance of a graph in each worker to do the trick.

ok, I got it now that the support GremlinHadoop will have to cassandra is as a reader. So, what is the recommended way to persist this data back to the cassandra/elasticsearch cluster?

Collin, We are using JanusGraph in production where I work (for about 1 or 2 weeks now, before that we used Titan) and I know other companies that still uses Titan in their production environment. So

Hello there, This might be a stupid question, but when running tasks in Hadoop do we have access to the index backend? If no, what happens when we run something like the PageRankVertexProgram and the

Hi Raj, Do you need Janusgraph's OLAP part? If not, you might probably succeed in your scala 2.11 project if you simply exclude tinkerpop spark-gremlin from your janusgraph dependency. Note, I did

You say it would take some work. Do you have a ballpark estimate my customer can use for planning? Presumably, when Tinkerpop 3.3 snapshots get to "candidate" stage, you start tooling for them. After

Sounds like ES is not started or cannot connect. Are you using `bin/janusgraph.sh start` or do you have a standalone ES deployed? I'd suggest double checking the IP and port that ES is listening on,
