> Prune cuboids by capping number of dimensions
> ---------------------------------------------
>
> Key: KYLIN-2363
> URL: https://issues.apache.org/jira/browse/KYLIN-2363
> Project: Kylin
> Issue Type: Improvement
> Reporter: fengYu
> Attachments: Dimension Capping.md
>
>
> 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+
