             Summary: Hybrid model for multiple realizations/cubes
                 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: v0.7.3


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;
