Gremlin vertex programs / graph computers using Gremlin.Net?-CodePudding

Are vertex programs / graph computers supported by Gremlin.Net? Or is it only supported on JVM Gremlin implementations?

CodePudding user response：

You cannot write a VertexProgram in Gremlin.NET. Those must be written in Java. You could however execute that JVM-written VertexProgram with .NET if you submit a script with your traversal referencing that program. There is an example of that approach here with more details, but I'll paste some code here:

gremlin> result = graph.compute().program(PageRankVertexProgram.build().create()).submit().get()
==>result[tinkergraph[vertices:6 edges:0],memory[size:0]]
gremlin> g = traversal().withEmbedded(result.graph())
==>graphtraversalsource[tinkergraph[vertices:6 edges:0], standard]
gremlin> g.V().elementMap()
