Re: Use index for sorting
We use special strategy that rewrite order comparator for supporting missing values https://gist.github.com/mad/6bef960d51d7a0d89a8c310851023303

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!

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.

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;

Re: Property with multiple data types
Maybe I'm completely wrong, but would I be right to say that "labels" are the equivalent of Java classes? Like, one label represents a Java class and graph properties represent a class properties? So,

Re: Centric Indexes failing to support all conditions for better performance.
Hi Christopher,
I don't have any workaround in mind except testing and comparing query latencies.
I have created https://github.com/JanusGraph/janusgraph/issues/2283 which hopefully can be addressed
