Re: [Neo] Java outof 64 GB ram

Ok, here is the final code. First of all, i walk around all the nodes and edges, and finally I do a Traverse for storing some information. //Query 1 public static void getNodeMaxOutDegreeNeo(final EmbeddedGraphDatabase neo, final IndexService indexService) { Node idNode;
