Hi Joe, Do you mean with threadsafe transactions that requests from different client threads should be handled independently, that is in different JanusGraph Transactions? In that case, I think you wa

Great stuff! Is is really motivating to gain a much deeper understanding of the JanusGraph inner workings and get practical advice at the same time. Marc

Hi Nikita, Do you use the spark web UI? In the executor tab you can follow the stderr link and see any logged or printed output. No idea why they use stderr. Best wishes, Marc

Hi Senthilkumar, I remember the Gremlin.version() output of 1.2.1 in the gremlin console of the janusgraph distribution is a bug somewhere. You can look in the lib folder and see that janusgraph-0.6.1

Hi Senthilkumar, Sounds like the "getting started deployment scenario", see https://docs.janusgraph.org/operations/deployment/#getting-started-scenario JanusGraph servers only need to have the exact s

Hi Nikita, JanusGraph can be run as a server or in embedded mode. gremlin-server.yaml is for configuring JanusGraph Server. With JanusGraphFactory in the Gremlin Console you instantiate embedded Janus

Hi Nikita, Possibly, your previous setup included JanusGraph Server and you had a remote connection from the Gremlin Console to JanusGraph Server. In that case, succesful gremlin requests are committe

Hi Nikita, Sorry for asking the obvious, but are you sure you committed the addV() transaction with a g2.tx().commit() before closing the Gremlin Console? Best wishes, Marc

Hi Joe, What is slow? Can you please check the Expero blog series and compare to their reference numbers (per parallel spark task): https://www.experoinc.com/post/janusgraph-nuts-and-bolts-part-1-writ

Thanks for reporting back! Unfortunately, java still has big problems using multiple versions of the same library, so your current approach is not a guarantee for success for future version updates (a

Hi Joe, Your issue description is not complete. To start: what version of JanusGraph do you use? what spark master do you use? The easiest way to find the guava version of JanusGraph is to download th

Hi Scott, Another approach is to take snapshots of the Cassandra tables and Elasticsearch indices after creating the schema and indices. Note that there are some subtleties when taking snapshots of no

OK, you can try and increase the java stack size used by Gremlin Server: $ export JAVA_OPTIONS='-Xss4m' $ bin/janusgraph.sh start https://www.baeldung.com/jvm-configure-stack-sizes

So, after interpolation, your string expressions looks like: g.addV("place").property("location", Geoshape.geoshape(Geoshape.getShapeFactory().polygon().pointXY(42.5636137, 1.4294247).pointXY(...).poi

Your code does work in the Gremlin console:: gremlin> graph = JanusGraphFactory.open('conf/janusgraph-inmemory.properties') ==>standardjanusgraph[inmemory:[127.0.0.1]] gremlin> g = graph.traversal() =

Hi Dmytro, Can you please present an easily reproducible scenario, preferably using the default "bin/janusgraph.sh start", like I showed, with gremlin console output and starting with an empty db/cass

Hi Dmitry, Here you go again: g.addV().property('location', Geoshape.line([[52, 0] as double[], [52, 2] as double[]])) g.V().elementMap() 21:09:39 WARN org.janusgraph.graphdb.transaction.StandardJanus

Hi Dmitry, It is not clear to me whether you have problems to get any geo predicate working or that your specific example is the issue. Can you first confirm that the following works for you (on a cle

Answer to your other question: What you do is certainly allowed, but has drawbacks compared to building a separate java package: building janusgraph-core takes more time (slower development cycle) giv

Hi Nikita, gremlin console does a lot of imports for you, but does not cover the full JanusGraph and TinkerPop APIs. So, sometimes you have to do an import yourself. In this case: gremlin> import org.
