Hi,
There is something confused me . In kylin 1.3 ,the dimension types are
hierachy/derived/normal and mantory when create a cube in the dimensions
step. In kylin 1.5.1 there 2 types including normal and derived in the
dimensions step, and in the advanced setting , aggregation group has some
aggregating manner of hierachy/mantory/joint.
I test 1.3 including 2 derived dims and 2 hierachy dims(also has 3
columns each dims, level1-> level2 -> level3), I said it has 4 dims in the
traditional BI way, but in kylin ,it's 10 dims.
In kylin 1.5.1, I can't create hierachy dims directly, but I can create
it for derived dims or normal dims first, then in the aggregroup , make it
to hierachy dims. but I don't know how to count it in traditional BI way.
We can discuss about the dims, and the different dims definition.
