> 需要。即使所有属性、点类型和边类型都已经在 HugeGraph 里提前创建好，hugegraph-loader 依然必须有 mapping 文件（struct.json），用来告诉 loader 如何把 CSV 文件的每一列映射到图数据库的 schema 上。没有 mapping 文件，loader 无法解析你的 CSV 数据和字段对应关系。 > > schema 配置文件（如 schema.groovy）只在你需要自动创建 schema 时才需要。如果所有 schema 元素都已存在，可以不用再执行 schema 文件，只要保证 mapping 文件字段和 schema 完全对应即可。 > > 参考社区讨论和 loader 测试用例，struct.json 是必须的，schema.groovy 可选（已建好 schema 时不用）[详见](https://github.com/apache/incubator-hugegraph-toolchain/issues/680#issuecomment-3218174858)。 > > _To reply, just mention [@dosu](https://go.dosu.dev/dosubot)._ > > How did I do?
