Re: Very slow performance when opening a new session

Hi Roy, I can confirm your observation using the standard 'bin/janusgraph.sh start' from the full janusgraph distribution. I just used the the gremlin console with: :remote connect tinkerpop.server

Janus multiple subgraphs

My understanding is that a Janus server can host multiple graphs, but they are isolated and cannot be queried together. I'd like to know if/how it's possible to split one single graph into multiple

Re: JanusGraph System Requirements

I think you need to qualify this a little better. For example, 100GB data is relatively small. Would easily fit in a single AWS i3.large. But what's going to be your analytical load? How many queries

Sounds good. Will check in the gremlin-users group. Thanks Boxuan!

Hello, What would the system requirements for JanusGraph be with 100 GB of data? Thanks

Re: How to filter out step 3 vertex list based on step 1 vertex

That’s a great question! To be honest I am not sure about the reason. My assumption is the __.out("edgeCB").is("B") is an anonymous child traversal within where() step, and thus it has no access to

Re: How to filter out step 3 vertex list based on step 1 vertex

Thanks Boxuan! I tried the single query and that worked accurately! On the other hand, I am still trying to figure out why the where traversal e.g. where(__.out("edgeCB").is("B")) didnt work. Is it

Re: How to filter out step 3 vertex list based on step 1 vertex

Hi Ronnie, Not sure if it's optimal but this should work: g.V().hasLabel("VertexB").as("B").in("edgeAB").out("edgeAC").as("C").out("edgeCB").as("B2").where("B", eq("B2")).select("C") You can also do

Hi, Assuming following schema VertexA--edgeAB-->VertexB VertexA--edgeAC-->VertexC VertexC--edgeCB-->VertexB Traversal step 1: start with VertexB, step 2: traverse edgeAB to find connected VertexA,

Re: Multiple or-steps are conflated when using the textRegex() predicate

Hi, Thanks for the quick answer. That seems to be it. Hopefully the fix will be available soon. Best regards, Mladen Marović

Re: Multiple or-steps are conflated when using the textRegex() predicate

Hi, Seems you are the victim of https://github.com/JanusGraph/janusgraph/issues/2231. There is an open PR to fix this: https://github.com/JanusGraph/janusgraph/pull/2567 Best, Boxuan

Multiple or-steps are conflated when using the textRegex() predicate

Hello! I came upon some unexpected behavior when running queries with multiple or() steps and string searches on mixed indexes and would like some clarification if this is intended or not. I have a

Re: Indexing on sub-attribute of custom data type

Hi Marc, Thanks for confirming about "creating an associated vertex which defines this custom data type" approach. In which case i would not be experimenting custom data types for now. Thanks for the

Re: Could not call index

At first I thought it might have something to do with 2 new indices I added yesterday, so I re-indexed them just in case. But the result is still the same. I'm having a hard time what does the error
