描述

Describe the bug

GraphLearn has implies int64_t as OID_T (see types.h) and current gremlin engine doesn't support string oids as well (see https://github.com/alibaba/GraphScope/issues/1265).

An exceptions should be thrown in g.graphlearn()/g.gremlin() is the oid type of vineyard graph is not compatible with those two engines.

贡献者指南

研究方向: 检查 types.h 中的类型定义以及 g.graphlearn() 和 g.gremlin() 的实现，找到应该进行类型兼容性检查的位置。
