gremlin

I would like to rank items according to a given users preference (items liked by the user) based on a random walk on a directed bipartite graph using gremlin in groovy. The graph has the following basic structure: [User1] ---'likes'---> [ItemA] <---'likes'--- [User2] ---'likes'---> [ItemB] Hereafter the query that I came up with: def runRankQuery(def userVertex) { def m = [:] def c = 0 while (c < 1000) { userVertex .out('likes') // get all liked items of current or similar user .shuffle[0] // select randomly one liked item .groupCount(m) // update counts for selected item .in('likes') // get

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 connected to a remote gremlin server via gremlin groovy shell. Connection succeeded. But for any remote command I try to execute it gives timeout error. Even for command :> 1+1 gremlin> :remote connect tinkerpop.server conf/senthil.yaml ==>Connected - 10.40.40.65/10.40.40.65:50080 gremlin> :> 1+1 Host did not respond in a timely fashion - check the server status and submit again. Display stack trace? [yN] org.apache.tinkerpop.gremlin.groovy.plugin.RemoteException: Host did not respond in a timely fashion - check the server status and submit again. at org.apache.tinkerpop.gremlin.console

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

Im using OrientDB type graph. I need syntax of Gremlin for search same SQL LIKE operator LIKE 'search%' or LIKE '%search%' I've check with has and filter (in http://gremlindocs.com/ ). However it's must determine exact value is passed with type property. I think this is incorrect with logic of search. Thanks for anything. Daniel Kuppitz Try: g.V().filter({ it.getProperty("foo").startsWith("search") }) or g.V().filter({ it.getProperty("foo").contains("search") }) You can use filter with a bit of regex: gremlin> g = TinkerGraphFactory.createTinkerGraph() ==>tinkergraph[vertices:6 edges:6]
