Neo4j with Gremlin-Scala

gistfile1.scala

import org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph
import gremlin.scala._

val dbPath = "/tmp/test" + math.random
val timeStart = System.currentTimeMillis
val graph = Neo4jGraph.open(dbPath)
val sg = ScalaGraph(graph)
val gs = GremlinScala(graph)

// graph.tx.open()
(1 to 30000) foreach { _ ⇒
  sg.addVertex("some label")
    .setProperty(s"property ${math.random}", math.random)
}
// graph.tx.commit()
val timeEnd = System.currentTimeMillis

val vertexCount = gs.V.count.head
println("---------------")
println(s"time to create: ${(timeEnd - timeStart) / 1000f}s")
println(s"vertex count: $vertexCount")
println("---------------")
graph.close

Without a bulk api for neo4j it takes nearly 70s to create 30k vertices.

There is currently no publicly available build artifact of tinkerpop3 that contains neo4j-gremlin, so this all depends on custom local builds.
