GremlinScala only provides a wrapping layer where it makes sense. In this case it looks like you're just using the main tinkerpop Graph interface, so Gremlin-Scala isn't involved. You can do just the same in Scala with g.createKeyIndex("my_key",classOf[Vertex])
here is my code from your sample:
import com.tinkerpop.gremlin.neo4j.structure.Neo4jGraph val graph: Neo4jGraph = Neo4jGraph.open("E:/scratch/test47") val gs = GremlinScala(graph)
Both 'gs' and 'graph' has no .creatKeyIndex function for me.
I think it's a blueprints method. But Neo4jGraph
implements that interface...
Please be aware that this this is all for tinkerpop3 - blueprints doesn't exist any more (it was in tinkerpop2). I'll update the readme shortly so that other's don't get down the wrong route, too.
Here are some pointers for code and documentation: https://github.com/mpollmeier/gremlin-scala/tree/tinkerpop3 https://github.com/tinkerpop/tinkerpop3/blob/master http://www.tinkerpop.com/docs/current/
For your question in particular: https://github.com/tinkerpop/tinkerpop3/blob/master/neo4j-gremlin/src/main/java/com/tinkerpop/gremlin/neo4j/structure/Neo4jGraph.java#L288
Looks like there's a Schema manager that let's you manage indices. Tinkergraph (the dummy graph implementation) has a createIndex function.
How can enable indexing in gremlin-scala? Apparently in Java gremlin there is a feature like this: gremlin> g.createKeyIndex("my_key",Vertex.class)
