hongbin ma commented on KYLIN-1747:
-----------------------------------

what does the "exception" here mean? did you mean "except mandatory"?
however if it's "except mandatory", I don't see why and how it's excluded, can you please elaborate?

> Kylin doesn't calculate all 0 combinations (exception mandatory dimensions) today; There wasn't specific consideration, but this may lead some query be slow.
> Investigate to remove that design, and make sure all functions (including query, merge cuboid statistics, etc) won't be broken.
