Hi there, Recently I am trying to measure Janusgraph performance. When I was trying to run benchmark using Janusgraph 0.5.3, I found too low performance when testing pagerank and wcc. The code I used

HI Marc, I have tried it. And finally I got complete Graph500 vertices and edges loaded. But there is a still weird thing that I found the same exception reported in the log. Could you please explain

Hi Boxuan, Thank you for the response. I tried by forceClosing all management instances except the current one before setting "tx.log-tx". Management is getting updated with latest value, this is not

Hi Mark, Thanks for the suggestions. Narrowed down the issue to JanusGraph's support for Azul Prime JDK 8, which generates nanosecond precision for Instant.now() API, as compared to the millisecond

Hi Shipeng Qi, The system that you use might be too small for the number of threads in the loading code. You can try to decrease the number of threads from 8 to 4 with: private static ExecutorService

I suspect this is due to stale management instances. Check out https://developer.ibm.com/articles/janusgraph-tips-and-tricks-pt-2/#troubleshooting-indexes and see if it helps.

Hi there, I am new to Janusgraph. I have some problems in loading data to Janusgraph with Cassandra CQL as storage backend. When I tried to load Graph500 to Janusgraph, planning to run benchmark on

Hi Boxuan,For existing JanusGraph setup, I am updating tx.log-tx configuration by setting management system property as mentioned in

Thank you, this is exactly what I look for.

Hi Toom, Do you want to ALWAYS make sure the vertex is indexed? If so and if you happen to use Elasticsearch, you can set See

Hello, The vertex that has just been created are not immediately available on mixed index (documented here [1]). I'm looking for a way to make sure the vertex is indexed, by waiting the mixed index

Janus supports "properties of properties", ie. properties defined on other properties. How is this represented with graphml? Should I use nested elements like this <node> <data

janusgraph-full includes Gremlin Server

What is the difference between janusgraph-<version>.zip and janusgraph-full-<version>.zip?

Hi Laura, Your assumption about ordering of nodes and edges is correct, see the warning at: https://tinkerpop.apache.org/docs/current/reference/#graphml For your use case it seems that you can simply

Hi Ronnie No idea what is going on here, but just being pragmatic: the bin/janusgraph.sh script starts Cassandra, Elasticsearch and Gremlin Server using the conf/janusgraph-cql-es.conf graph

Sorry I'm asking to this list because I can't find this information anywhere else. Is it possible to have an <edge> element nested inside a <node> element with graphml? And will Janus be able to read

Thank you Boxuan for the response. I will create a feature request. Regards, Radhika

Hi Radhika, Unfortunately, there is no such API. If you are willing to dive into JanusGraph source code, you can modify StandardTransactionLogProcessor::fixSecondaryFailure method and build JanusGraph
