I've been running into the "Frame size (##) larger than max length (15728640)!" on a query and I've tried several options for increasing the value but none seem to be recognized. Can this value be

Hi Jason, Thanks for posting an example! I have been having a rough time finding some example code. That said, the build fails (on mac using java 8 update 110 and maven 3.3.9): [INFO]

I followed the steps described in the documentation to access the JanusGraph using REST calls. But I am getting error message as follows. curl -XPOST -Hcontent-type:application/json -d

Hi Rob, I went through the tinkerpop code, just PageRankMapReduce, ClusterCountMapReduce, ClusterPopulationMapReduce has memoryKey function. (I found the description "We still recommend users call

So I understand that if I open up separate transactions and modify the schema, a commit on one of the transactions will fail. What I don't understand is why adding edges of the same name between

Hi Rob, It sound like your battling skills are OK! I have never used the PersistedOutputRDD option myself, but if your are stuck you could also try the

Last battle before I think this is all done, I need to extract the output without collecting results to the driver and exploding the memory there. Gremlin has a page at

Hi Marc, Managed to get this working. The final code ended up being simple, but the configuration properties you need to set has changed across different versions of JanusGraph/Tinkerpop and finding

Thanks Ted! Folks can find the snapshot distribution zip at: https://oss.sonatype.org/content/repositories/snapshots/org/janusgraph/janusgraph-dist/0.1.0-SNAPSHOT/ I've created an uber simple Java

Hello, We're still working some of the kinks out, but the first JanusGraph 0.1.0-SNAPSHOT has been deployed. This includes a snapshot build of the zip distribution. You can check it out and kick

Hi Rob, Yes, you are diving in, I read. JanusGraph data are available as HadoopGraph using the HBaseInputFormat and CassandraInputFormat classes. You can find examples on the old Titan forum,

Thanks (again!) for the quick response. I've got Gremlin to use the existing SparkContext successfully. I'm trying to test this, however I'm also finding triggering the traversal from Scala

Hi Rob, Documentation is not abundant on this, I agree. So I read through the spark-gremlin source code and saw that SparkGraphComputer can reuse the SparkContext using the

Hi Ivan, When I first read your question on March 6 I thought this one was not for me, but I see now that you still did not get an answer. I agree it looks suspicious, but there is still one thing I

These are all good suggestions. Not sure if it would be feasible to recreate your db, but if it was, you may be able to use edge TTLs:

I'm definitely not a Titan/Janus or ES expert so I'm not sure how it works. But I imagine if you had an index by label, timestamp, asc, then you would only ever hit the tip of the index

Hi, I have a Spark-based program, which writes vertices and edges to a JanusGraph cluster (Cassandra backend). Once the write is complete, I would like to execute an OLAP traversal for all vertices,

Hi Marc, Thanks for this. Yes it is a mixed index with elasticsearch as the backend. I've thought about the poor man's approach and I'm going to give that a try. In fact I can probably query

Thanks Robert, I will follow the path you have suggested and see what that I can achieve. The problem with the g.V() queries is that it is iterating over all vertices, so it is fast when I first

Hi Kevin, By an "elasticsearch index" you do mean a mixed index, don't you? Actually, indexing does not help you too much, because your query still hits 1/7 of your edgestore. The way to go here is to
