GitHub user dosubot[bot] added a comment to the discussion: 关于电网拓扑数据导入
<!-- Answer --> Neo4j 和 HugeGraph 在 schema 和数据导入方式上有不少差异，尤其是边标签（EdgeLabel）和主键（primary key）映射。HugeGraph 导入失败最常见的原因是 struct.json 里边的 source/target 字段没有正确映射到顶点的主键字段，或者这些字段没有包含在 selected 列表里，导致边无法关联到顶点（即使顶点已经导入成功）[参考](https://github.com/apache/incubator-hugegraph/issues/2749)。 建议你把 schema.groovy、struct.json 和几行典型的电网数据（顶点和边）发出来，我可以帮你逐条检查映射和格式，定位问题。也可以把报错日志贴出来，能更快找到原因。 导入前可以先确认： - schema.groovy 里每个顶点定义了主键，边标签只连接一种源/目标类型 - struct.json 里边的 source/target 字段要和顶点主键一一对应，并且都在 selected 里 - 数据文件里顶点和边的 label、主键字段和 schema 完全一致 如果你需要 struct.json 或 schema.groovy 的参考模板，也可以直接说你的数据结构，我可以帮你写一份适配 HugeGraph 的导入配置。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
