我再查询的时候 可能时间长有时候会导致一个节点的graphd服务挂掉 重启之后 再去查某个节点的连边数 会发生和之前查询结果不一样的情况 有遇到这个问题的吗？ |

这种问题，建议把复现步骤写清楚，发到 github 上或者论坛里 |

这么只言片语的话，很难给你有效帮助 |

我们对 bug 是很关注，提出来肯定有人看 |

-
想你说的这个情况，graphd 本身是无状态的，它挂不挂都不会影响查询结果，可能是别的原因造成的 |

-
不一定是有 bug，需要有详细的复现步骤，才能搞清楚发生啥了 |

你要变，你就告诉我变成什么样子，否则的话，我需要你告诉我你变什么，不变什么，这个事情才算清楚，“变什么” + “不变什么” 其实就等于最终你要什么样子 |

通过不写一个内容来隐含它不变，是比较容易出错的 |

我理解额这点要不就完全写全 要不就只写需要更改的部分 所以搞得我有点困惑 |
Beta Was this translation helpful? Give feedback.
-
你自己看看语法，是只写需要变更的部分的，只不过变更哪个属性，这个属性自己的内容要写全。 |
Beta Was this translation helpful? Give feedback.
-
你可以认为属性是变更的粒度。 |

这个跟mysql里面变更一列是一样的 |
Beta Was this translation helpful? Give feedback.
-
column type 不算是属性吗 |
Beta Was this translation helpful? Give feedback.

额 我确实不了解mysql额 |

语法设计是追求清楚，一般不追求最小信息量。就像我说“我喜欢你”，此处的“我”有时候也可以省略嘛，我表的态肯定代表我自己，但我把主语说清楚是“我”，表达更清楚。当然不同数据库设计的不一样，有的可能也支持很细粒度的语句。 |

如果对细粒度的语句有需求，可以到社区提 feature request |

@程训焘 请问有没有nebula关于raft实现的博客额 |

这个镜像为啥没了呀 |

「?：这个镜像为啥没了呀」 如果你用 docker 的话，可以直接在 docker extensions 里装 nebulagraph，非常方便，几秒钟就拉起来服务了。 |
