> 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;
