Hi Pawan, OK, I did a small upgrade session myself and did not encounter any issues (apart from having to set numTokens: 4 in conf/cassandra.yaml). This is what I did: Start from a fresh janusgraph-fu

Hi Pawan, It seems I miss the practical experience, but it seems you have to set graph.allow-upgrade=true (although it is not clear whether this applies to all version changes or only to "storage vers

Hi Pawan, This part of your stacktrace suggests that something changed on your Cassandra cluster or with the graph_user. So, check the CREATE permission, with your admin or try to create a keyspace wi

Hi Mladen, You are right, your issue is different than the one I mentioned about GraphManager. I mentioned earlier that the JanusGraph test suite covers your use case: https://github.com/JanusGraph/ja

No, JanusGraph does not have a storage backend for a single-node cluster that persists to single file (such as sqlite would). It is possible though to have a single Cassandra instance co-hosted on you

Hi Mladen, After your original post, the following issue was reported: https://github.com/JanusGraph/janusgraph/issues/2822 Marc

Hi Mladen, The good news: there actually is an explicit MultiHost test for this in the janusgraph test suite: https://github.com/JanusGraph/janusgraph/blob/v0.6.0/janusgraph-cql/src/test/java/org/janu

Hi Anjani, In individual query for a subgraph of 40 nodes will typically take between 0.1 and 1 seconds (with scyllaDb being the fastest storage backend). The number of 200 TPS can be reached easily b

Hi Chris, Hard to interpret your report. It maybe worthwhile to try the documented way of remote connection with traversal.withRemote(...) or Cluster.open(...): https://tinkerpop.apache.org/docs/curre

Hi Anjani, How large is your graph, can you hold it in memory in its entirety? How large are the subgraphs you want to retrieve in terms of width and size? What are your requirements regarding TPS? Wh

Thanks for this information [I mean the facts, this forum is not intended to spread opinions on third parties]. After, checking, I was surprised myself. The deviation from the JE has occurred since v0

Hi Chris, Thanks for reporting. I could confirm the exception you got by using the console and server files from the distribution. I got the right results, though, when I changed the contents of conf/

Hi Jan, When you say "We stopped testing HBase 1 in our CI solution already in branch 0.3" does that mean you are not sure whether HBase1 tests would run on a custom build for 0.4+? If so, the code wa

Hi Priyanka, The case you describe sounds suspect and might be a JanusGraph issue. Your last remark ("If i add some delay b/w two operations then vertices are getting removed correctly.") gives an imp

Hi Laura, https://tinkerpop.apache.org/javadocs/current/full/org/apache/tinkerpop/gremlin/structure/io/graphson/GraphSONReader.html People do not want to put effort in explaining graphSON because that

Hi Laura, If you want to know, you would better ask on the TinkerPop users list. Note that graphSON is not designed as a human-readable or standardized interchange format, but rather as interchange fo

Nice work!

The behavior you describe sounds like the behavior one experiences for transactions occurring in parallel. So let us investigate some further: do you use CompositeIndex or MixedIndex? is it certain th

Hi Laura, You can only add a single level of metaproperties. One can understand this from the java docs. In a TinkerGraph a regular property is a TinkerVertexProperty with a property() method to add m
