I am using AWS Neptune with gremlin and I want to get the id of a vertex with all properties of the vertex in one query. How can I do this? I have tried g.V().hasLabel('file').valueMap(true) but the output is: { "fileSize": [ "9170" ], "Gremlin.Net.Process.Traversal.T": "f1fce58306f85ca7050503160640d735c9919c8fc85881d65de80bfe31b5ca24", "mimeType": [ "text/html" ] } No label and no id is there. The problem with project('id','label',' fileSize', 'mimeType', 'malwareSource'). by(id). by(label). by('fileSize'). by('mimeType'). by('malwareSource') is that the propertie malwareSource is sometimes

I am now trying to learn how to connect to Neo4j server and run Cypher queries on it using Bulbflow from Python. And the thing I do not understand is the difference between two possibilities to connect to the neo4j server: 1) Graph from bulbs.neo4jserver import Graph g = Graph() 2) Neo4jClient from bulbs.neo4jserver import Neo4jClient client = Neo4jClient() Could anyone please explain the conceptual difference here? And which way is it better to choose if I then want to execute (quite a lot of) Cypher queries against the server and ultimately in parallel? PS: I do not have enough reputation to

I need some help to be confirm my choice... and to learn if you can give me some information. My storage database is TitanDb with Cassandra. I have a very large graph. My goal is to use Mllib on the graph latter. My first idea : use Titan with GraphX but I did not found anything or in development in progress... TinkerPop is not ready yet. So I have a look to Giraph. TinkerPop, Titan can communique with Rexster from TinkerPop. My question is : What are the benefit to use Giraph ? Gremlin seems to do the same think and is distributed. Thank you very much to explain me. I think I don't really

I use Titan 0.4.0 All, running Rexster in shared VM mode on Ubuntu 12.04. How could I properly delete a graph in Titan which is using the Cassandra storage backend? I have tried the TitanCleanup.clear(graph) , but it does not delete everything. The indices are still there. My real issue is that I have an index which I don't want (it crashes every query), however as I understand Titan's documentation it is impossible to remove an index once it is created . You can clear all the edges/vertices with: g.V.remove() but as you have found that won't clear the types/indices previously created. The

I am very new to Gremlin. I am trying to build a graph on DSE graph using Gremlin. I am able to create the vertices: a = graph.addVertex(label, 'label1', 'key', 1) b = graph.addVertex(label, 'label1', 'key', 2) c = graph.addVertex(label, 'label2', 'key', 1) d = graph.addVertex(label, 'label2', 'key', 2) Now i am looking to automatically add edges between two nodes with differents label where the property 'key' matches (i.e create and edge between a and c, and between b and c). I am stuggling to do that. I tried to do the following g.V().hasLabel("label1").sideEffect{g.V().("label2").has("key"
