A critical security vulnerability was reported in Apache Log4j 2 on December 9, 2021: CVE-2021-44228 [1]. JanusGraph itself is not directly affected by this vulnerability as it still uses log4j 1.2

Thanks for your report. Can you please provide the following details: Which version of JanusGraph do you use? Are you sure you did not set the storage.drop-on-clear property to false? Do you have

Hi Tendai, I do not understand the concept of row contention. Is not this config row just the row that is retrieved most often on the region servers that contain it and are not other rows on these

Hi, We are running embedded Janusgraph (0.5.3) with an HBase backend (2.1.6) in our Spark jobs. Each Spark executor creates an instance of Janusgraph. At times there can be over 500 executors

The same problem does not exist when using InMemory Storage Backend.

Hi All, I have the setup using Cassandra backend (Azure Cosmos DB fully managed). Seems it is not possible to add two edges with the same label. gremlin> g.addV() ==>v[4288] gremlin>

Hi all. I'm creating dynamic graphs using configuredGraphFactory in bigTable. I'm able to create them but when I try to delete them then it seems that they only get deleted from janusgraph-server and

Thanks a lot Marc for the answer and the link to the gremlin-users group. I was wondering if there's something "implementation specific" done in JanusGraph that could help in having such progress

Hi Albert, I tried with the GraphOfTheGods with janusgraph-0.5.3: So, I guess you did not mean to say that these traversals should fail. If it has anything to do with the way you use the

Hi Marc, Thanks for reply. Yes, we are also doing thorough testing to check any compatibility issue and thus so far we haven't found any except this one. Strange thing is that the current issue posted

Hi Umesh, I assume that checking the compatibility matrix at https://docs.janusgraph.org/changelog/ made you post the additional comment about cassandra 4.0.0 :-) Indeed, support of cassandra 4.0 is

Hi Marco, Interesting idea! From what I read about the EventStrategy, this is a feature stemming from TinkerPop and questions about it could best be addressed there. Note however that gremlin OLTP

Hi all, I've successfully using in my application an EventStrategy's listener with both the DefaultEventQueue and the TransactionalEventQueue: they gave a way for the listener to be invoked while the

One update: Cassandra version is 4.0.0 -- Sincerely, Umesh Gade

Hi, We just upgraded janus to 0.6.0 and started observing an issue which was working earlier. Scenario is, we open a connection with read/write CL="ONE" using JanugGraphFactory. But when quorum

Janusgraph (version 0.5.2) can be made to throw a NullPointerException using the following traversals: g.V().has(label, eq('User')).has(label, eq(null)) g.V().has(label, without('User')).has(label,

Hi Anya, In v0.6.0 the bin/janusgraph-server.sh start script does not start Cassandra any more. Are you sure you did start Cassandra ("cassandra/bin/cassandra") before starting JanusGraph? Also check

Hi Mladen, Indeed, there is still a load of open issues regarding TTL: https://github.com/JanusGraph/janusgraph/issues?q=is%3Aissue+is%3Aopen+ttl Your last remark about empty vertices sounds

Hi Mark, thanks for the response. As described in https://docs.janusgraph.org/schema/advschema/, TTL is already supported. However, there are two issues in my case: a) Changing the TTL is supported,

Hi Mladen, Just two things that come up while reading your story: the cassandra TTL feature seems promising for your use case, see e.g.
