求limit下推功能

使用nebula创建了一个商品知识图谱,存储类目、SPU以及从属关系,使用如下语句查询spu顶点时耗时特别长,该顶点的入边大概有3000w,希望能针对这个场景做下推优化

   GO FROM 1239472222637158456 OVER spu_belongto_category REVERSELY | LIMIT 10

下面是简化后的建图语句

CREATE SPACE goods(partition_num=1024);
USE goods;
CREATE TAG spu(mid int, name string);
CREATE TAG category(mid int, name string);
CREATE EDGE spu_belongto_category(spu_mid int, category_mid int, source string);

建议使用max_edge_returned_per_vertex参数限制返回数据量。
