我在OrientDB中插入大量（几百万）边缘时遇到问题。在java中，我有一个包含~5000行和列的矩阵，其中每个条目表示对象之间的相似性值。我想将此信息插入OrientDB。
但是在创建了200k到400k之间的边缘之后，发生了ODatabaseException，我还没有找到解决这个问题的方法。
我正在通过以下方式创建边缘：使用SQL Batch，我将SQL查询添加到字符串并为每100个边执行批处理。每个SQL行都如下所示：
CEATE EDGE similarity FROM #10:0 TO #10:1 SET score = 0.5
我应该以不同的方式做这件事吗？是缺乏记忆问题吗？我一直无法找到解决方案。
感谢。
修改：
我正在使用异常和一些代码更新问题：
代码：
public void saveHouseCharacteristicsSimilarities(double[][] houseSim,
ArrayList<OHouse> houseList) {
OrientGraphFactory factory = new OrientGraphFactory("plocal:/directory");
OrientGraphNoTx graph = factory.getNoTx();
int counter=0;
String query = "BEGIN\n";
for (int h1 = 0; h1 < (houseList.size() - 1); h1++) {
for (int h2 = (h1 + 1); h2 < houseList.size(); h2++) {
counter++;
query += "create edge similarity from "
+ houseList.get(h1).getRid() + " to "
+ houseList.get(h2).getRid() + " SET score = "
+ houseSim[h1][h2] + "\n";
if (counter % 100 == 0
|| ((h1 == (houseList.size() - 1)) && (h2 == (houseList
.size() - 1)))) {
query += "COMMIT";
graph.command(new OCommandScript("sql", query)).execute();
query = "BEGIN";
}
}
}
graph.shutdown();
}
异常（在此特定点我已经保存了250000条边）：

尝试这样的东西来创建边
OrientVertex vertex = graph.getVertex(houseList.get(h1).getRid());
OrientVertex vertex2 = graph.getVertex(houseList.get(h2).getRid());
vertex.addEdge("similarity",vertex2,new Object[]{"score",houseSim[h1][h2]});
答案 1 :(得分：0)
好吧，问题似乎不是东方本身，而是程序运行的glassfish服务器。由于某种原因，Glassfish终止了与东方的联系。无论如何，在服务器外运行程序解决了这个问题。谢谢！
