Re: JanusGraph 0.5.2 and BigTable

Could this be related to delays in indexing? I don't know how to figure out of such exists, but assuming this happens - how does a traversal behave when looking up based on an index key when the key

Re: JanusGraph 0.5.2 and BigTable

From time to time, usually after setting up a fresh copy of the BT and Janus, I'll encounter errors relating to locking. However this doesn't happen every time. Sorry, I can't see to be able copy the

JanusGraph 0.5.2 and BigTable

Hi All, I'm experiencing an issues with running JanusGraph (on top of GKE) against BigTable. This is the general setup description: We are using a single node BigTable cluster (for development /

Thank you very much, I'll try that. Toom.

We use special strategy that rewrite order comparator for supporting missing values https://gist.github.com/mad/6bef960d51d7a0d89a8c310851023303 пятница, 4 декабря 2020 г. в 09:59:13

Aggregating edges based on the source & target vertex attributes

Hello, I request your help regarding the janus graph query which I am trying to construct. Let's consider the following graph where each vertex denotes a person and the edge between any two vertex

Re: Condition where-inV-is does not work

Hi Anton, To compare objects you need the eq() predicate, not the is() step (see https://tinkerpop.apache.org/docs/current/reference/#a-note-on-predicates). Also note that JanusGraph uses

Re: addE doesn't create more than 1 edge

Thanks for your explanation. I got the idea, that "many" side of "one-to-many" relationship should go first when adding edges.

Re: Condition where-inV-is does not work

Thanks for reply. In real query I don't have an ID, that's why I use traversal in where clause. Tried this one, but it does not work either:

Re: How to improve traversal query performance

Hi Marc, Thank you for your too much advice. I will keep learning about Gremlin query for better performance. Thanks a lot! Manabu. 2020年12月11日金曜日 22:40:21 UTC+9 HadoopMarc:

Re: addE doesn't create more than 1 edge

Marc is correct about "It is not a bug: the addE() step only adds one edge per traverser". I think query by Mark will create a self link. Below query might work (not

Re: addE doesn't create more than 1 edge

Hi Anton, It is not a bug: the addE() step only adds one edge per traverser. Also, using g.V() twice is an anti-pattern. Try it the other way around, something like (not

Re: Running OLAP on HBase with SparkGraphComputer fails with Error Container killed by YARN for exceeding memory limits

Re: Configuring Transaction Log feature

The code explains behavior. the api sets start time to null instead of Instant.now() hence different behaviour. public LogProcessorBuilder setStartTimeNow() { this.startTime = null; return this; }
