Re: Janus multiple subgraphs
Hi Laura, unfortunately, you would have to handle this in your application layer. For example, you can use different labels, properties, indexes for different subgraphs.

Bulk loading
I've read the "Bulk Loading" chapter of the documentation several times but I still don't understand how to create a graph. Everything that I can find online is some Java or Groovy code.

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

Re: How to filter out step 3 vertex list based on step 1 vertex
Sounds good. Will check in the gremlin-users group. Thanks Boxuan!

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

How to filter out step 3 vertex list based on step 1 vertex
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,

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.
