Hi!
I am trying write select-query and my perfomance is very slow when I call method toList().
How I can improve this perfomace ?
My example:
long start;
long end;
try (GraphTraversalSource g = graph.traversal()) {
start = System.currentTimeMillis();
GraphTraversal<Vertex, Vertex> list2 = g.V().hasLabel("Entity");
end = System.currentTimeMillis();
System.out.printf("getGremlinTime: %d ms\n", (end - start));
start = end;
List<Vertex> res2 = list2.toList();
end = System.currentTimeMillis();
System.out.printf("toList: %d ms\n gremlin count: %d\n", (end - start), res2.size());
}
Debug log:
getGremlinTime: 13 ms
2020-12-31 14:19:01.336 WARN 14144 --- [ main] o.j.g.transaction.StandardJanusGraphTx : Query requires iterating over all vertices [(~label = Entity)]. For better performance, use indexes
toList: 12025 ms
