Hi Ravikumar,
TinkerPop provides a quick start for graph visualization with the Gephi plugin for the gremlin console.
Cheers, Marc

Possibility of index out of sync with graph
Is it possible for the index (either Elasticsearch or Solr) to be out of sync with the store (cassandra or hbase) or is the store commit contingent on the index commit? If it is possible, what

Is there a visual viewer for JanusGraph?

Cassandra/HBase storage backend issues

Re: Low throughput on Janus vs Neo4j (Tuning issues?)
Hey Robert,
1) For Neo4J I ended up using your patch (I believe) to get Neo4J 3.0.3 working with TP 3.2.3
2) The queries were submitted as scripts. The connection to server was through the session

Low throughput on Janus vs Neo4j (Tuning issues?)
So I've been evaluating JanusGraph on a single machine that is also hosting a Cassandra instance. It seems that I am unable to achieve the same throughput that other users here seem to have. Currently

Re: HBase unbalanced table regions after bulkload
Hi Ali,
Thanks for returning feedback about your experiments.
The docs have a section on graph partitioning, warning about a too large number of partitions and suggesting to use explicit partitioning

Re: HBase unbalanced table regions after bulkload
Hi Marco,
I think it has nothing to do with the region-count and hbase does not ignore any region in any circumstance. Since my regions are imbalaced (only 100 regions have data in them), data size

Re: Bulk loading using Json, python or Scala?
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!

Re: HBase unbalanced table regions after bulkload
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

Re: HBase unbalanced table regions after bulkload
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

Re: Bulk loading using Json, python or Scala?
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:

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

HBase unbalanced table regions after bulkload
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
