Subject Re: wonder how to config a blacklist of cuboids

Thank you for your reply! 

I think it is a math game. It already meets the need via the existing rules.

Sorry to bother you without some deep research.

Thank you so much!

Hi, so far Kylin allows user to enter a whitelist, no blacklist. 

If you can list all the cuboids you want, you can do that with the whitelist + a minimal aggregation
group (say only 1 dim in that group). Because at least you should have one agg. group.

In the picture, I see you want to avoid that cuboid that C+D appeared at the same time (mutually
exclusive). You can do that by separating them into two agg groups: 1) ABC, 2) ABD .Then you
will have
the following cuboids: ABCD, ABC, AB, BC, AC, ABD, AD, BD, A, B, C, D

When I config a cube ,  I fund Mandatory Cuboids in Advanced Setting. As the explain in official
website , it means Whitelist of the cuboids that you want to build.
I wonder how to config a blacklist of the cuboids that I do not want to build.

In my case, I just want to remove the cubid who contains the Dimension of C and D. And I have
no idea how to config it.
Or should I filled the Mandatory Cuboids with all cuboids that I need ??
Wating for your reply!
