XIE FAN commented on KYLIN-2363:
--------------------------------
I agree with this idea. And I think we can extend this idea a little: allow
users to select exactly which cuboids they need in a visual way. Users can
choose what cuboids they need in the front-end and only these cuboids will be
materialized. For example, users can choose to calculate all the 1-D and 2-D
cuboids and part of the 3-D, 4-D cuboids and exclude the other.
> support limit of dimensions in a cuboid

> 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+
