You are using unique(), this takes lock for each operation. Try to handle uniqueness through application instead of Janus. ~AnkurG

Unique index is globally. ~AnkurG

As I understand labels are used for partitioning. Does the same apply for clustering? I.E I create vertices and edges with custom properties. Assume I have a unique property called: 'nodeId'. Now I

You can use coalesce step to do a check or insert query. http://tinkerpop.apache.org/docs/current/reference/#coalesce-step Something like

I should add I do this query (to eliminate duplicate vertices) before adding each Vertex as I know that in the existing RDBMS same nodes exist multiple

I am writing an app that loads an existing RDBMS based graph implementation into JanusGraph. I create this index: JanusGraphManagement mgmt = javaGraph.openManagement(); if

Hi, Like Neo4j has inbuilt graph visualization tool or datastax has studio; keylines is good framework to draw graph. Do we have similar kind of open source tool/framework for JanusGraph. ~AnkurG

One Option I thought of that should have worked but doesn't is: Assuming I have a method to create between 'from' vertex and 'to' vertex: Iterator<Edge> edgesIter = from.edges(Direction.OUT,

I have an app where I am migration a d non graph DB graph to Janus. So I create the graph when I first start the app. Using cassandra backend. I have an issue where 2 vertices have "identical" edges

Hello, Netflix is hosting a Graph Database meetup on Sep 19: https://www.meetup.com/Graph-Databases-and-Frameworks/events/243156558/ Join us to learn how Netflix deployed TitanDB (the predecessor of

Hi Himanshu, g.V().count() requires a full table scan, so normally you would use an OLAP query for that. Unfortunately, OLAP queries with HBase also still have some performance issues,

Hi all, I have a Janusgraph with more than 100K vertices. When I try to retrieve all the vertices through a java code using a gremlin query, it takes more than 10 mins to list all the vertices. I am

My bad, thnx Jason.

Thanks. I startup JG instance in my local and use this code to connect to it GryoMapper.Builder builder = GryoMapper.build().addRegistry(JanusGraphIoRegistry.getInstance()); cluster =

Suny, in the original post you wrote about "in-memory database for unit testing and cassandra for the real application data on same janusgraph instance". I assumed you mean same JG instance for both

Thanks for you response. So I should use 2 instances of JG - One with in-memory backed to perform unit testing and other with cassandra to run functional use cases ?

The in-memory database was built for testing - http://docs.janusgraph.org/latest/inmemorystorage.html#_ideal_use_case_2 If it's only the data access layer (e.g. gremlin queries) being tested, I would

Oh, and I would always use separate JG instance for testing if it is possible.

For unit testing you should use mocks otherwise this is not unit testing. For functional testing I use TinkerGraph as much faster and less resource hungry backend. Janus in-memory should be fine,

Hi, I am using janusgraph with cassandra as backend for my application. If i want to write a unit test to verify saving/retrieving of data, is mocking the only way ? Can i use in-memory database for
