Hi Sai, What happens in createTraversal()? What do you get with g.V(1469152598528).elementMap() if you open the graph for OLTP queries? Best wishes, Marc

Hi Pasan, The multiple janusgraph nodes share the same storage backend, so the common caching is done in the storage backend. Best wishes, Marc

Hi Sai, The calling code you present is not complete. The first line should read (because HadoopGraph does not derive from JanusGraph): Graph graph = GraphFactory.open("read-cql.properties"); Best wis

Hi Sai, This exception is not really related to this thread. JanusGraph with SparkGraphComputer can only be used with the TinkerPop HadoopGraph. Therefore, the example in the JanusGraph ref docs has a

Many organizations use JanusGraph on this scale. Insertion of data is slow so you need massive parallel operations to do an entire bulk load overnight. Most people use tools like Apache Spark for this

In theory (not used in practice) the following should be possible: make a snapshot of the ScyllaDB keyspace after the ScyllaDB snapshot is written, make a snapshot of corresponding ES mixed indices re

Hi Sai, In your last post a line with ConfiguredGraphFactory.createConfiguration(new MapConfiguration(map)); is missing. A complete working transcript that works out of the box from the janusgraph-ful

Hi Sai, I suspect this is related to your setting: #do not auto generate graph vertex id graph.set-vertex-id=true Can you try without? Best wishes, Marc

Hi Sai, "ConfigurationManagementGraph" is not meant to be opened. Please follow the exact instructions described in: https://docs.janusgraph.org/basics/configured-graph-factory/#configurationmanagemen

Hi Joe, Good question and I do not know the answer. Indeed, the documentation suggests that the DB cache stores less information than the transaction cache, but it is not explicit about vertex propert

Hi Shiva, This sound more like a cluster management question than a JanusGraph question, so my suggested steps are: try to run a simple mapreduce job using HBase, like Hbase's built-in rowcounter exam

https://github.com/JanusGraph/janusgraph/issues/2588 For further explicitness I added the following example: gremlin> g.V().has('x', neq('lion')).elementMap() ==>[id:4264,label:Some,x:x2,y:??] ==>[id:

Hi Sergey, The mere mortals skimming over the questions in this forum often need very explicit examples to fully grasp a point. The transcript below, expanding on the earlier one above, shows the exac

Hi Alessandro, The executors tab of the spark UI shows the product of spark.executor.instances times spark.executor.cores. I guess spark.executor.instances defaults to one and EMR might limit the numb

Hi Alessandro, Yes, please include the properties file. To be clear, you see in the spark web UI: spark.master=yarn spark.executor.instances=12 and only two executors for 700+ tasks show up, while oth

Hi Alessandro, I assume Amazon EMR uses hadoop-yarn, so you need to specify spark.master = yarn, see: https://tinkerpop.apache.org/docs/current/recipes/#olap-spark-yarn Once you can run the TinkerPop

Hi Sergej, The example string "??" you used was not an ordinary string. Apparently, somewhere in elasticsearch it is interpreted as a wildcard. See my transcript below with some other property value a

Hi Carlos, I read the preceding discussion with Stephen Mallette, which says: From the logs, while loading this graph, Cassandra driver is almost always warning that all batches are over the limit of

Hi Sergey, I think I see your point, but for completeness can you be explicit on step 1) and specify your mgmt.buildIndex() statements? Best wishes, Marc

Hi Toom, OK, I tried two things. I start with the janusgraph-full-0.5.3 distribution and run (this has gremlin server running with conf/janusgraph-cql-es.properties): $ bin/janusgraph.sh start Now I s
