问题的具体描述
1.创建A空间定义TAGt1、t2 定义EGDE_TYPEe1,e2
2.执行exchange任务生成sst 生成 t1/e1相关数据,执行download,执行ingest,校验数据,无任何问题
3.执行major compact，过程失败
4.执行exchange任务生成sst 生成 t2/e2相关数据,执行download,执行ingest
5.执行major compact，成功
6.校验数据发现部分t1点/e1关系数据丢失(t1、t2为相同的vertex_id),t1数据丢失的点现象表现为- 执行 match (v) where id(v)=‘xxxx’ return v; 无数据返回
- 执行 match (v)-[e:e1]-(v2) where id(v)=‘xxxx’ return v; 无数据返回
- 执行 match (v)-[e:e2]-(v2) where id(v)=‘xxxx’ return v; 有数据返回,但点上无任何tag
