> dim-attribute query on cube
> ---------------------------
>
> Key: LENS-34
> URL: https://issues.apache.org/jira/browse/LENS-34
> Project: Apache Lens
> Issue Type: Task
> Components: cube
> Reporter: Amareshwari Sriramadasu
> Assignee: Jaideep Dhok
> Fix For: 2.0
>
>
> If only dim-attributes are queried from cube, cube query rewriter should pick facts with least weight and even an aggregated fact if the dim-attribute is available in the aggregated fact.
> This issue to verify the above behavior by writing a unit test and fix the behavior if it is different from above.
