gremlin

问题 I am trying to initialize an in-memory graph using TinkerGraph. Firstly, i have defined the bean in my context xml file and tried to initialise the TinkerGraph. My intention is to unit test the classes that i have created for forming the gremlin queries, the end queries that i get from these classes are in the form of a string, so in order to execute them through the TinkerGraph, i have the used the approach given in the following post: Get Gremlin query as a String and execute it in java

问题 Im working on a Cosmos DB app that stores both standard documents and graph documents. We are saving both types via the documentdb api and I am able to run graph queries that return Graphson using the DocumentClient.CreateGremlinQuery method. This graphson is to be read by a web app and the graph displayed for user viewing and so on. My issue is that I cannot define the version of the Graphson format returned when using the Microsoft.Azure.Graphs method. So i looked into Gremlin.net and that

问题 I'm on the Gremlin console and connected to an AWS Neptune DB g.V().hasLabel('Risk').toList() provides the expected results, but when i try to assign the results to a variable risks = g.V().hasLabel('Risk').toList() I get the message below - the token recognition error is clearly throwing on the variable name because when i change the variable name the position and "at" part of the message changes. {"requestId":"650d7c4b-44d1-43f8-b9a3-fbf085cc3ead","code":"MalformedQueryException",

问题 I've been looking at the Gremlin graph language, and it appears very powerful. However, whilst running through what it can do to evaluate it against requirements, I came across a case that I can't seem to complete. Assuming Gremlin is started, and using its example database: gremlin> g = TinkerGraphFactory.createTinkerGraph() ... gremlin> g.V.out('knows') ==>v[2] ==>v[4] So this shows vertices that have an edge of 'knows'. However, I want to find vertices that do not have edges of 'knows'.
