> Key: KYLIN-5649
> URL: https://issues.apache.org/jira/browse/KYLIN-5649
> Project: Kylin
> Issue Type: Bug
> Components: Query Engine
> Affects Versions: 5.0-alpha
> Reporter: Zhiting Guo
> Assignee: Zhiting Guo
> Priority: Major
> Fix For: 5.0-beta
>
> Attachments: When query contains computed columns, fail to guarantee
> the priority of using the aggregate index to answer the aggregate query.pdf
>
>
> After enabling the "kylin.query.use-tableindex-answer-non-raw-query = true" &
> & "kylin.query.layout.prefer-aggindex = true" parameter, the aggregate query
> can match the aggregate index and the basic detail index, but the final hit
> is the basic detail index. What is puzzling is why the aggregate query is
> answered using the basic detail index?
