>                 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+
