Chuanlei Ni commented on KYLIN-2363:
------------------------------------
If we only have the 4-D cuboids, but we need to query about 3-D information.
Obviously, kylin cannot get the result from Hbase directly.
But can kylin calculate the resultset based on the 4-D cuboid on fly?
Is this idea possible for the current kylin architecture which store the cube
on hbase and do some post-processing via coprocessor?

> 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+
