Yes, I forgot that one, VertexPrograms need to be written in java. If you are not familiar with setting up java projects, you can take a look at the examples at: https://github.com/JanusGraph/janusgra

The easiest way is to write your custom VertexProgram for TinkerPop. If it runs in TinkerPop, it will also run in JanusGraph. There are other ways, though, see two examples in: https://github.com/Janu

Kerberos has a reputation for being complex. I would try to first get the pure TinkerPop example working, using the TInkerPop Gremlin-server and Gremlin Console distributions. Also check the log outpu

You are mixing up two procedures: Gremlin Server Krb5Authenticator is for authenticating gremlin clients towards Gremlin Server. Apparently, you do not want it, so remove it from your configs. Apparen

Adding new types of storage or indexing backends to JanusGraph is not straightforward. So, unless you are a seasoned java developer and have some time to spare, you will have to use the available stor

Connecting gremlin console to gremlin server goes like: cluster = Cluster.build(<hostname>).jaasEntry(<entry in gremlin-jaas.conf file>).protocol(<serverPrincipalName>).create() and see https://tinker

Hi Nikita, I do not understand: Krb5Authenticator runs inside Gremlin Server and authenticates users of gremlin clients (e.g. Gremlin Console). Why would you run JanusGraphFactory in the Gremlin Conso

Hi Aman, Without saying that I understand everything of the JanusGraph behaviour that you describe, I can add the following: when accessing the graph via JanusGraph server (what you call the gremlin A

Hi Krishna, The properties you cite are not quoted in the right way: "storage.hostname: "cass01,cass02,cass03"" Are these typos in the post or in your actual code? Best wishes, Marc

Hi Yingyie, My answer above was not accurate. Actually, on my system the startup only succeeds with: $ cd janusgraph-full-0.6.1 $ bin/janusgraph.sh start So, it fails when you start it the way you did

Hi Yingjie To see a NullpointException from the very first start is rather disappointing, so thumbs up for your patience! To make things reproducible, what OS + verion and JVM + version do you use? Di

Hi Doug, Some questions back: In terms of https://docs.janusgraph.org/operations/deployment/ how does your cluster look like? Have you located any performance bottlenecks? What kind of gremlin queries

What JanusGraph version do you use? Recent TinkerPop versions use Order.asc instead of Order.incr. Best wishes, Marc

If you do not use sessions, remote requests to Gremlin Server are committed automatically, see: https://tinkerpop.apache.org/docs/current/reference/#considering-transactions . Are you sure that commit

Hi Lixu, JanusGraph-0.6.0 had various changes to the ConfiguredGraphFactory which might have solved your issue: https://github.com/JanusGraph/janusgraph/issues/2236 https://github.com/JanusGraph/janus

Hi Laura, No answer but some relevant search results: https://groups.google.com/g/gremlin-users/c/jUBuhhKuf0M/m/kiKMY0eHAwAJ The graph.set-vertex-id property at: https://docs.janusgraph.org/configs/co

Hi Laura, JanusGraph only allows to configure a custom SchemaMaker with the schema.default property. Googling on SchemaMaker hits some (unmaintained?) projects that could help: https://github.com/grap

How fast is immediately? A well dimensioned cassandra or scylladb cluster (with its own block cache!) should be able to serve requests at the ms level. https://www.scylladb.com/2017/09/18/scylla-2-0-w

Hi Matt, Adding to what I stated above about independent composite indices for separate graphs on the same storage backend, the issue turns out to more nuanced for mixed indices on an indexing bakend,
