hi,
Sorry for disturb you , I am a chinese engineer , Excused for my bad english :) . Recently, I am learning Neo4j and trying to use it in my project . But When I make a Pressure on neo4j with 5 theads , 10 theads, 20 and 30, I found the nodes inserted to the Neo4J is not change obvious (sometimes not change ~ ~! ). Does it not matter with threads ? the kenerl will make it Serial ? Is there any documents or something about The performance of Neo4j ? thanks for your help The program as follows: I put this function in ExecutorService ,with 5/10/30 threads. then test for the nodes inserted into at same time .(The counts have not changed obviously) Transaction tx = null; Node before = null; try { for (int i = 0; i < 1000000; i++) { if(stop == true){ return; } if (graphDb == null) { return; } try { if (tx == null) { tx = graphDb.beginTx(); } // 引用计数加1 writeCount.addAndGet(1); int startNodeString = name.addAndGet(1); Node start = getOrCreateNodeWithOutIndex("" + startNodeString); if (before == null) { // 根节点.哈哈哈 I got U Node root = graphDb.getNodeById(0); root.createRelationshipTo(start, LEAD); } if (before != null) { before.createRelationshipTo(start, LOVES); } int endNodeName = name.addAndGet(1); Node end = getOrCreateNodeWithOutIndex("" + endNodeName); start.createRelationshipTo(end, KNOWS); before = end; // 每一千次 commit一次 if (i % 100 == 0) { tx.success(); tx.finish(); tx = null; } } catch (Exception e) { System.out.println("write : = " + e); } } } catch (Exception e) { } finally { tx.finish(); } } _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
