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.

Hello, I have a local setup of JanusGraph 0.6.0 with Cassandra 3.11.9. I am creating a graph using the ConfiguredGraphFactory. For this, I am using the bundled properties and yaml files and creating

Hi Marc, Adding additional data - Checking duplicate data with uniqueness constraints on name_cons field - gremlin>

Hello, I have a graph (Janusgraph 0.5.3 running on a cql backend and an elasticsearch index) that is updated in near real-time. About 50M new vertices and 100M new edges are added every month. A

Hi Marc; Yes, We are committing the transaction after each operation. how do you know about "duplicate vertex creation" when "it returns only 1 record"? Vertex is being ingested with the same data

Hi Pawan, Your code mirrors the example at https://docs.janusgraph.org/advanced-topics/eventual-consistency/#data-consistency for the greatest part. Are you sure the changes on graphMgmt get

Hi Matthias, Thanks for taking the trouble to report this. It took a while, but your report did not go unnoticed: https://github.com/JanusGraph/janusgraph/issues/2857 Best wishes, Marc

Hi Everyone, I am facing a duplicate vertex creation issue even though the unique index is present in that property and when i retrive the data with the same index it returns only 1 record. Please see

I have a follow-up question in addition to my reply above: Is there any guide for understanding the JanusGraph metrics available? I have written a basic metrics integration but I'm finding it quite

Hey again Boxuan, thanks for your help in this thread! 1) Read speed is quite fast, at least as fast as I would expect for using a remote database like BigTable. 2) That is a good idea, I will try

I am not an expert on this and I've never used BigTable or GCP before, but here are my two cents: 1) Did you test the read speed? Is it also very slow compared to writing? 2) Did you try using an

Hey there, folks. Firstly I want to say thanks for your help with the previous bug we uncovered. I'm evaluating JanusGraph performance on BigTable and observing very slow write speeds when writing

Hi Marc, Your solution works if the configuration hasn't been changed yet. If you change the index backend and set a wrong hostname, you cannot access your data anymore: mgmt =
