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,

I want to load GraphOfTheGodsFactory using cassandra & es. It is giving me this exception when i try to do gremlin> graph =

Sorry! I found it's my own fault. The property is a String type, and is a mixed index. while this went wrong, gremlin> g.E().has('contents','hdfs').values() Could not find a suitable index to

Hi everyone, The Opensource Graph Technologies meetup community in London has been nicely growing the past few months! We've been organising it (GRAKN.AI) and we've had cool talks from people Apache

Here's a recent one: https://twitter.com/CELUM/status/857934890934964225

FYI, the Titan mailing list is here. What does your index definition look like?Are you using JanusGraph or is this a problem you can recreate on JanusGraph?

This issue has been reported https://github.com/JanusGraph/janusgraph/issues/228 Please follow the discussion there.

cqlsh communicates using CQL interface, but JanusGraph uses Thrift. I'd suggest double checking that the RPC settings (rpc_address, rpc_port) in cassandra.yaml match what you have in

Hi Collin, I'm not aware of what "level of testing and rigor that went into the 1.0 release of Titan". The version is just a number, and I wouldn't get too hung up on it if you've tested it in your
