> 可以，HugeGraph 支持通过 PrimaryKey（主键属性）直接绑定主键值来实现边的创建。具体来说：
>
> * 当你在 schema 中为顶点设置了 primaryKeys（如 id），顶点的 ID 策略会自动变为 PRIMARY_KEY。
> * 这时，顶点的唯一标识就是主键属性的值，无需显式指定顶点 ID。
> * 在创建边时，可以直接用主键值（如 "pk_001"、"pk_002"）作为源/目标顶点的标识，HugeGraph 会自动根据
VertexLabel 和 PrimaryKeyValues 生成顶点 ID 并完成边的绑定。
>
> 你的 Groovy 示例是正确的用法：
>
> schema.vertexLabel("person").primaryKeys("id").create();
> graph.addVertex(T.label, "person", "id", "pk_001", "name", "张三");
> graph.addVertex(T.label, "person", "id", "pk_002", "name", "李四");
> graph.addEdge(T.label, "knows",
> T.source, "pk_001", // 源顶点主键值
> T.target, "pk_002"); // 目标顶点主键值
> 官方文档说明：
>
> * PRIMARY_KEY 策略下，顶点 ID 由 VertexLabel + PrimaryKeyValues 生成，类型为
String，且数据会基于主键去重，无需手动指定 ID

> * 在边的映射中，如果顶点采用 PRIMARY_KEY 策略，需指定一列或多列用于拼接生成顶点的 ID，即可直接用主键值绑定
