Hi all:
As was shown in some ppts about kylin, the max num of dimensions may less
than 16, or they would lead to large time-cost during cube building.
If I have the following dimensions, what's the total num of dimensions:
1 normal dimension: DimA
1 derived dimension: DimB, and the derived columns are dimB1 and dimB2
1 hierarchy dimension: DimC, and the levels are dimC1, dimC2 and dimC3
