<!-- Answer --> HugeGraph 在顶点 ID 策略为 PrimaryKey（PRIMARY_KEY）时，如果插入两条 primaryKey 值完全相同的数据，系统会自动进行“去重/覆盖”处理： - **同一个 VertexLabel 下，primaryKey 组合值相同的顶点，只能有一条。** - 如果你插入一条 primaryKey 已存在的顶点数据，HugeGraph 会直接覆盖原有顶点（即后插入的会替换前面的），不会报错，也不会新增一条重复数据。 这种行为适合大批量导入或幂等写入场景，用户无需手动查重，HugeGraph 会自动保证 primaryKey 唯一性，实现“以主键为准，后写覆盖前写”[相关文档说明](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/guides/desgin-concept.md)。 **补充说明：** - 如果你希望插入时能感知是否发生了覆盖（比如需要提示），可以考虑用 AUTOMATIC 策略（但性能不如 PRIMARY_KEY）。 - 如果用 CUSTOMIZE_STRING 或 CUSTOMIZE_NUMBER 策略，则需要你自己保证 ID 唯一性，系统不会自动查重。 如需具体代码示例或批量导入配置，可以继续补充需求。 <!-- Dosu Comment Footer --> *To reply, just mention my name [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
