[jira] [Created] (KYLIN-2363) support limit of dimensions in a cuboid

fengYu created KYLIN-2363:
-----------------------------

             Summary: support limit of dimensions in a cuboid
                 Key: KYLIN-2363
                 URL: https://issues.apache.org/jira/browse/KYLIN-2363
             Project: Kylin
          Issue Type: Improvement
            Reporter: fengYu


the scene like this:

I have 20+ dimensions, However the query will only use at most 5 dimensions in all dimensions, so cuboid that contains 5+ dimensions(except base cuboid) is useless.

I think we can add a configuration in cube, which limit the max dimensions that cuboid includes.

What's more, we can config which level(number of dimension) need to calculate. in above scene, we only calculate leve 1,2,3,4,5. and skip level 5+
