High HBase backend 'configuration' row contention

NullPointerException comparing PredicateCondition (in equals method)
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 PredicateCond

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 s

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 tra

Bindings for graphs created using ConfiguredGraphFactory not working as expected
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

Cleaning up old data in large graphs
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 plausible

Cleaning up old data in large graphs
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. https://www.geeksforgeeks.org/time-to-live-ttl-for-a-column-in-c

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 committed

Usage of CustomID on Vertexes
Hi Hazal, Your comment is correct: the graph.set-vertex-id feature is not documented further than this, so using it is not advised. You are also right that lookups in the index require additional proc

I read some conceptual confusion, so let me try: a single query is handled by a single janusgraph instance (In this case JanusGraph Server) you can handle many queries from many nodejs clients in para

Queries with negated text predicates fail with lucene
Hi Toom, Yes, you are right, this behavior is not 100% consistent. Also, as noted, the documentation regarding text predicates on properties without index is incomplete. Use cases are sparse, though,

Options for Bulk Read/Bulk Export
Hi, There are three solution directions: if you have keys to your vertices available, either vertex ids or unique values of some vertex property, you can start as many gremlin clients as your backends

Query performance with range
Hi Claudio, Paging with range can only work with a vertex centric index, otherwise the vertex table is scanned for every page. If you just want all results, the alternative is to forget about the rang

Thread goes into Waiting state forever
Hi Tanroop, Does the problem also occur if you replace v() with V().limit(1) inside your query? If not, at what result size does your issue start to occur? Btw, your post has a typo: "user" and "uidx"
