fengYu commented on KYLIN-2363:
-------------------------------
I know the configuration and what it means, In my scene, for example, I have 6
dimensions : A/B/C/D/E/F， I need at most 2 dimensions(in where and group by) in
any query, so, I need calculate cuboids like AB/AC/AD/AE/AF/... and A/B/C/D/E/F
and skip ABC/ABD/ACD/... and ABCD/ABCE...
so I need a configuration specify the max dimensions that cuboid contains which
need to be calculated.
> support limit of dimensions in a cuboid

> 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+
