「夜色曾沁凉：算法包3.1.0 对应的图库版本应该为多少呢？ 目前我用的是3.2.1的 考虑升级的话 是升级到3.4.1还是3.3.0」 看版本兼容性的话，应该是 3.4.1。不过我去确认下 |

逃脱不了就是我要先跑一边查询语句，然后看一下结果格式是不是符合预期，然后再解析 |

ResultSet 里面是有相关数据的 |

查什么肯定是要提前知道啊，不然返回值怎么写？ |
Beta Was this translation helpful? Give feedback.
-
就是我得先验证我的结果 |

是不是我想要的 |

一个简单的例子 |

这个是要的，不过就是你的查询结果格式是不能提前预知的 |
Beta Was this translation helpful? Give feedback.
-
结果就是这样的，就是我能通过查询的输入知道我的输出是什么样子，以及该怎么解析。而不是我先知道了结果集长什么样子，再去解析 |

返回结果 和 实体/对应类型的数组 绑定 |

-
嗯，是要提前知道的，但是这个“知道”的代价有点繁琐 |

有没有更好的泛化处理的方式 |

GraphQL查询是这样的， |
Beta Was this translation helpful? Give feedback.
-
我看目前这种应该都是类GraphQL的形式 |

现在有这样一个问题，在写代码的时候，需要对每个语句的结果有个预期模板才能去写数据解析的逻辑，一个简单的例子是比如查询索引，需要先跑一边响应的语句才能知道响应结果的格式然后再去解析，不知道大佬们这种情况怎么解决的 |

「程训焘：这种玩法扩展性很差，数据量大了就不行了，除非你不考虑扩展性」 感谢大佬，请问大佬在图库的使用方法上有什么推荐吗？ |

点可能会变，每个点的内容也可能会变，感觉可能删了重建图会简单点吧 |

「只打鱼不晒网：[图片]」 这个是hive元数据MySQL的信息 |
Beta Was this translation helpful? Give feedback.
-
就是为了拿到你Hive的元数据 |
Beta Was this translation helpful? Give feedback.
-
所有数据几个g |

如果是通过前端进行操作，前端会把这整张图一下存到后台 |
Beta Was this translation helpful? Give feedback.
-
但是前端的操作不会实时对数据库内容操作，只会在修改完成后才会发送图数据入库请求 |
Beta Was this translation helpful? Give feedback.
-
好像也没找到 |

MATCH (v) RETURN count(v); |
Beta Was this translation helpful? Give feedback.
-
前辈们，MATCH (n)-[r]->(m) RETURN n,r,m limit 10，这么写不对吗 |

「ZGT：感谢大佬，请问大佬在图库的使用方法上有什么推荐吗？」 推荐多看NebulaGraph的文档！ |

盲猜就是你上面连的那个MySQL链接 |

应该是个子图吧，总不至于直接拎一整个库出来改吧。 |
Beta Was this translation helpful? Give feedback.
-
是个子图可以读到缓存里，拿个图框架存着做可视化，用户的修改你可以存下来（不管什么方式，持久化mysql也行，做个小git那种可以回退的也行），然后最后入库直接把最终修改映射到nebula里，哪些要删哪些要加。内存里的直接丢了也行或者你看办法能不能复用。 |
