Hi Madhan It is exciting news that you have just made available this work under the APL2.0 license!!! Standard RDBMS, though not as scalable as the NoSQL storage backends, might provide an easy start

Hi Dany, Some anwers: computation happens inside janusgraph (not the storage backend) and janusgraph runs as part of gremlin server yes, a query and its computations run on a single gremlin server ins

This question is also asked to the gremlin user group, where it can be best answered: https://groups.google.com/g/gremlin-users/c/-oBWRUxF_Hw

Hi James, Best approach is to do a custom build of janusgraph with the version of TinkerPop changed (you can use -D skipTests because TInkerPop API have not changed). With the maven dependency plugin

Also check: https://github.com/JanusGraph/janusgraph/commit/7fbf6567f259b2514e64e7a70e668e7975b38a72 This suggests that no new library conflicts occur. Marc

The janusgraph docs and gitrepo talk about ghost vertices or phantom vertices: https://docs.janusgraph.org/advanced-topics/eventual-consistency/#ghost-vertices https://docs.janusgraph.org/basics/trans

Hi Ted, Most probably you recognize my nickname from the answers I provided on this user forum on OLAP attempts with JanusGraph. I also co-authored: https://tinkerpop.apache.org/docs/current/recipes/#

Hi Ted, Yes, a short overview of OLAP questions from the user list sounds like a good idea and is easy to prepare. It need not be long; 10 minutes including a few questions for clarifications would do

Hi Abhay, The hadoop client picks up configs from the JVM classpath. So, simply add /etc/hadoop/conf (or some other folder that keeps the hdfs-site.xml and other cluster configs) to your classpath. Ne

Is this what you are looking for (it includes an explicit example): https://docs.janusgraph.org/basics/configured-graph-factory/#updating-configurations You can version your graph in the storage and i

Hi Vinayak, Try: g.V().project('v', 'vcount', 'ecount').by(identity()).by(count()).by(bothE().count()) Best wishes, Marc

You really have to try this out and see. I can only answer from what I read in the ref docs. > Do I need to ConfiguredGraphFactory.close(GRAPH) before I update its configuration? The docs say the bind

Hi Vinayak, A new attempt: g = TinkerFactory.createModern().traversal() g.withSideEffect('vs', new HashSet()).withSideEffect('es', new HashSet()). V(1,2).aggregate('vs').outE().aggregate('es').inV().a

Hi Vinayak, Speeding up your query depends on your setup. 15.000 vertices/second is already fast. Is this the janusgraph inmemory backend? Or ScyllaDB? In a perfect world, not there yet, your query wo

Confirmed, could not find it either. Could you please add it as a comment to: https://github.com/JanusGraph/janusgraph/issues/1163 Unless someone comes up with a solution, it seems you will have to ke

Thanks. Still, my earlier answer remains unsatisfactory. Somehow, a new JanusGraph instance must be able to load an existing schema from the system table and have the information about label constrain

Hi Vinayak, Could you try in the gremlin-server.yaml with just: graphs: { ConfigurationManagementGraph: conf/janusgraph-cql-configurationgraph.properties } So, without the graph, graph1 and graph2 key

Hi Vinayak, You showed the error message from the remote console. Does gremlin server itself log anything particular about the ConfigurationManagementGraph after a restart? Marc

Please be sure to run all the steps (including a graph.tx().rollback() before index creation and a mgmt.commit() after update of the index) from the example in: https://docs.janusgraph.org/index-manag
