-----------------------------------
Summary: TopN support query UHC column without sorting by sum value
Key: KYLIN-2098
URL: https://issues.apache.org/jira/browse/KYLIN-2098
Project: Kylin
Issue Type: Improvement
Reporter: Shaofeng SHI
Assignee: Shaofeng SHI
Fix For: v1.6.0
In previous version, TopN doesn't support to query the UHC column directly (as
it is not in dimension), like this SQL: "select distinct seller_id
from test_kylin_fact where cal_dt >date'2012-06-01'
" (assume "seller_id" is a "group by" column in TopN measure)
In some BI tool, it need fetch the distinct values of the dimension before
generating the chart, so it's better to serve such query directly.
