[jira] [Created] (KYLIN-1320) Do not calculate cuboid between different group

fengYu created KYLIN-1320:
-----------------------------

             Summary: Do not calculate cuboid between different group
                 Key: KYLIN-1320
                 URL: https://issues.apache.org/jira/browse/KYLIN-1320
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v1.0
            Reporter: fengYu


We find it is slow while buiding cube, most time speed on cuboid calculating, and I find kylin will generate cuboid between groups which is not same with what we expected. so we delete leftover mask and just calculate cuboid in a single group.

I know it has updated in kylin-2.x, However currently in kylin-1.x, this can increase cube building speed.
