Yang Hao commented on KYLIN-2363:
---------------------------------
If there is no one to solve the problem, I want to solve it by not saving data
in step "Convert Cuboid Data to HFile". If the max dimension N has set, then a
row key with more than N column will be filtered. How about this solution.

> 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+
