------------------------------
@fengYu, yes, your understanding is very correct.

> Key: KYLIN-867
> URL: https://issues.apache.org/jira/browse/KYLIN-867
> Project: Kylin
> Issue Type: Improvement
> Components: Metadata, Query Engine
> Reporter: Shaofeng SHI
> Assignee: Shaofeng SHI
> Fix For: v1.0
>
>
> Scenario: users have a cube already built with the history data; Now they
> create a new cube which adding more dimensions; Due to some reason, user
> expects both the history cube and current cube can be scanned to get a full
> result set;
> A hybrid realization will be introduced, which is composed by multiple cubes,
> and these cubes have no overlap/gap on the partition date; Then the hybrid
> will delegate the query to all cubes, and then merge the results;
