简单调研下,对于桌面的版本,大家喜欢哪个图计算的库或者接口?networkx networkit gds或者其他 |

或者换一种思路,是不是率先用上 NebulaGraph 企业版,能更快做到老板! |

大佬们,你们用官方的Nebula Flink Connector写入了吗,一个数据 要写两遍 |

官方给的demo,8条数据,写到库里16条,有大佬知道咋回事吗 |

请问这种要查询两次分别获取 id 应该如何写? |

官网上的这个例子执行报错 |

「程训焘:这个报错不是说你的这个 insert 的 vid 超长,是 storage 在插入的时候,从 meta 读的这个 space 的 vid 是报错了。可以看看这个 space 是不是别的 insert 也不行,看看错误日志是不是有啥信息。」 好的,我怀疑是不是一个bug,因为之前这样是不会的,就是nebula graph崩了一次后出现的,而且我之前存进去能看到点和边查询几遍后也找不到了 |

vertex的模型可以理解为id加一个tag列表,每个tag中是tag名字和属性map |

是的 |

我下班后可以贡献一下我之前写的简单的解析类,大体思路很简单你拿到value wrapper之后可以用里面提供的类型判断方法判断基本类型,然后解析基本类型,还有几个特殊的list wrapper,mapper wrapper,vertex wrapper,edge,path这些递归解析就行 |
