Today, The Linux Foundation announced the creation of the JanusGraph project. We're excited to push forward the open source, collaborative effort on scalable graph databases that was initiated by the

Hi all, extremely excited that JanusGraph is out into the world! I have been working with Titan since 0.4.x and have been hoping for a long time to see new maintainers so that bug reports, pull

This is a big one for us as well, and while we have stuck with a schema that allows supernodes we've made all sorts of work arounds in our java code which accesses Titan. Although in our case we're

I was also delighted to read the notices about JanusGraph! High in my wishlist is: better support for installing JanusGraph in any of the major Hadoop distributions. Many users have had to face

> 2. Provide a well documented migration path from Titan 1.0 Have you already migrated your Titan 0.4 code over to Titan 1.0? -- Jason

> Related to this area, I think the "hands-off-the-backend" approach that the Titan project took should be ditched. I've heard this sentiment before, but my guess is that it will be a while before it

Yes, I've been on Titan 1.0 for quite some time now. I meant from Titan 1.0 to Titan 1.1 / JanusGraph. Maybe very little is needed - I haven't looked into the unreleased Titan 1.1 changes much.

Since I did want to use an index since performance is not ofessence at the current time and I did not want to use either Elastic Search or SOLR, I used the following in Gremlin: graph =

Try dropping the existing HBase table first (default HBase table name is janusgraph), and then create a new graph with graph = JanusGraphFactory.open('conf/janusgraph-hbase.properties') which does not

That was it Jason! Thanks! Could use a better error :-)

However, when I do the next step in the tutorial I get the following error: gremlin> GraphOfTheGodsFactory.load(graph) Unknown external index backend: search Display stack trace? [yN] N

If you are trying to do the tutorial without an index backend, you need to load the graph using this command instead: GraphOfTheGodsFactory.load(graph, null,

Thanks Jason! That worked.

Hi, I was wondering if the execution of a single query/traversal is on a single node or is the execution distributed across nodes ? I understand that the storage is distributed across many machines

What are the maven co-ordinates for downloading the Janus graph jars? is there one? Regards Ajay krishnan

Hi Karthik, The query execution is carried out by the JanusGraph instance, see http://docs.janusgraph.org/0.1.0-SNAPSHOT/arch-overview.html The JanusGraph instance can be your own application with

Hi Ajay, I believe there is just the git repo just now: https://github.com/JanusGraph/janusgraph You can clone the repo and do a local build, which will put the jars in your local .m2 repo, see the

hi, folks, first, very glad to see someone picking up Titan.... I am new in this area and looking for a couple pointers. Does JanusGraph(titan) reply on the datastore(such as HBase) for data

Hi, Demai JanusGraph/Titan takes advantage of the partition/shard capability of the storage backend. This is a high-level description of the graph partition.

Jerry, thanks a lot. appreciate the pointers.... Demai
