> Key: KYLIN-1693
> URL: https://issues.apache.org/jira/browse/KYLIN-1693
> Project: Kylin
> Issue Type: New Feature
> Components: Query Engine
> Affects Versions: v1.5.1
> Reporter: JunAn Chen
> Assignee: Shaofeng SHI
>
> For this case:
> table name : "tbl"
> columns: (dim_city, dim_industry, keyword, pv)
> the "keyword" column has a large cardinality, for about ten million.
> currently I can build "top100 pv" in (dim_city), (dim_industry).
> But I also want to build "top100 pv" in (dim_city, dim_industry) and "top100 pv of keyword" in (dim_city), (dim_industry) and (dim_city, dim_industrt).
