有人可以向我解释为什么将实体导入 Neo4j 需要 6 到 10 秒吗？

我正在使用带有Neo4jTemplate @Autowire-d 的自定义存储库的 Spring Data Neo4j。因此，当我坚持一个实体时，我会调用template.save(entity). 我不得不说，虽然实体有点重。它有 47 个属性，即字段，其中 3 个用@Indexed注释标记，其中 10 个是用 标记的其他自定义实体@RelatedTo。其中 5 个@RelatedTo字段是 type Set。这意味着实际上在导入这个重实体时，另外 10-15 个实体也可能被持久化并连接到它。

这是实际的问题还是我可以做些什么来加快这个过程？

我环顾四周，找到了，BatchInserter但它不关心索引。我找到了这个示例实现，但如果没有其他选择，我会尝试它。

所以我想我想了解的是，如果沉重的实体是缓慢持续或其他原因的原因。

我正在使用 Neo4j 1.8 并没有触及配置文件。

任何帮助表示赞赏。谢谢。

@Michael Hunger：
- 数据库中的数据量似乎没有影响。
- 我没有使用 AspectJ，所以我想我使用的是简单映射，对吧？你认为我会用 AspectJ 获得更好的性能吗？
- 我认为我没有跨越该save方法的外部事务。我正在使用 Wicket Web 应用程序中的数据库。如果我将 Neo4j 的 REST API 与Jersey REST 客户端一起使用会更好吗？
- 如果自定义类型的类中有一个属性，例如Area area，那么将为此自动创建另一个节点area以及主节点和 之间的连接area，对吗？所以没有必要template.createRelationshipBetween(entity1, entity2, type, properties, true)，对吧？要使用它，我必须做的是删除area属性，然后使用一些索引找到正确的area，然后手动建立连接。这是你的意思吗？

这就是我的保存方法的样子：

@Override
@Neo4jTransactional
public <T extends Identifiable> T save(T entity) {
    T saved = template.save(entity);
    Long savedId = saved.getId();
    Node savedNode = getNode(savedId);
    connectToContainerNode(savedNode, entity.getClass());

    return saved;
}

这是如何定义实体的示例（忽略 @ExcelCell 注释）。通常有一个抽象类被持久化实体扩展。如果我做错了什么，请告诉我。

  • 您能否分享您的实体或表现出相同行为的示例项目？
  • 您的数据库中已有多少数据？
  • 您使用简单映射还是高级映射？
  • 您是否有跨越该方法的外部事务save？
  • 我认为您的时间花在处理关系上（SDN 对每个关系进行重复检查）您可以尝试替换那些template.createRelationshipBetween(entity1, entity2, type, properties, true)跳过这些检查的关系吗？
