Summary: Support multiple group-by columns for TOP_N meausre
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: liyang
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).
