I see.. we need to use GraphML file. The issue here is our graph might contain billions of nodes, will Python client be able to handle that? Thanks!

I need a help in time series modelling, with Cassandra as the backend storage... Consider a model as below Has many Which Report Domain

Thanks, Dave! I am wondering what's the recommended format of the data, xml, txt or csv ?

Hi Ali, OK, I overlooked your config line "storage.hbase.region-count=1024". This is far too large a number, since HBase likes regions with a size of the order of 10GB, rather than the 130MB you

Hi Marc, As far as I know, even if yarn schedules executors unevenly, it does not mean that the data written across hbase will be uneven. The data is written hbase according to the key of the datum

You should be able to bulk load with any client that allows you to submit raw gremlin scripts to the server. For example, you can do it with ipython-gremlin, check out cell # 2:

Hi Ali, I have never tried to optimize this myself, but maybe you should also look into the docs at 12.3.30. storage.hbase ... storage.hbase.region-count The number of initial regions set when

Other than Groovy, is it possible to do bulk loading using Json, python or Scala? Any sample code could be provided? Thanks!

We are using cloudera 5.7.0 with java 1.8.0_74 and we have spark 1.6.0, janusgraph 0.1.1, hbase 1.2.0. I managed to bulkload 130GB of data into 1024 region hbase table in 2 hours 30 minute with 1024

Hi Elizabeth, For JanusGraph you should also take into account the TinkerPop documentation. A relevant pointer for you

That won't work if the framesize is not large enough.

This should give you the counts, highest first, by vertex id: g.V().group().by(id()).by(outE().count()).order(local).by(values,decr) Robert Dale

Using cassandra as the backend, I was trying to count edges {g.E().count} and of course ran into the framesize problem because I had a supernode. I found that I could identify which node was the

Hi all, I am new to Janusgraph, I have dived into docs of Janusgraph for almost two weeks, nothing found. I could only gather the scatted information and most of the time it will prompt some

Outstanding - thank you Jason. -gene

Here is my problem: We are using cloudera 5.7.0 with java 1.8.0_74 and we have spark 1.6.0, janusgraph 0.1.1, hbase 1.2.0. I try to load 200Gb of graph data and for that I run the following code in

Hi Misha , Thanks a lot for your response and useful information much appreciated. Thanks , Anurag

Hi Jamie, Good question, and I dig the ASCII art. To answert your question, they will describe the same graph as if you were running the Janus instances in their own JVMs. I've used both approaches.

We have a _domain specific_ REST API that is architecturally decoupled from JanusGraph. In other words, users of the REST API have no indication that their calls interact with JanusGraph, or even with

Make sure you're using a mixed index for numeric range queries. Composite indexes are best for exact matching. The console session below shows the difference: gremlin> graph =
