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

JanusGraphFactory.open() creates a graph. You need to create a graph traversal source. graph =

graph.io(IoCore.graphson()).readGraph("data/tinkerpop-crew.json”); Use this, this is able to load graphson format. ~AnkurG

Hi, I am using embedded janusgraph server (cassandra + ES). have generated two graphs by change following properties in default janusgraph-cassandra-es-server.properties :

Just to update problem got resolved, i was using without: mgmt.setConsistency(leadidCUniqueIndex, ConsistencyModifier.LOCK); After removing, this works like charms earlier in adding 300 vertex we

It is difficult to help with just a stack trace. Please provide a some more context of the problem, like the graph configuration, the schema definition, and the graph mutation code that is happening

We are using single node Janusgraph instance with embeded (cassandra and es). While adding multiple vertex getting following exception: org.janusgraph.diskstorage.locking.TemporaryLockingException:

OK. I got it. This works: val javaGraph = JanusGraphFactory.open(conf) val graph = javaGraph.asScala javaGraph.openManagement() etc... Thanks.

I suspect that, but I couldn't see how I get to the janusgraph api from the ScalaGraph. This is my code: val conf = new BaseConfiguration() conf.setProperty("storage.backend", "cassandra")

The janusgraph management API is not part of Tinkerpop, and thus not of gremlin-scala. So, you can just use the janusgraph java API within scala. Hope this helps, Marc Op dinsdag 5 september 2017

I am using gremlin scala and I can't seem to find the management API so I can create indexes. Any pointers?

FYI, Solr support for LIST and SET cardinality should be in 0.2.0

Thank's I will get that going in my app.

Titan/JanusGraph has been using 2.11 and TinkerPop has been using 2.12 for the last 2 years or so. JanusGraph overrides TinkerPop's version. There is only one copy of jline in either TinkerPop or
