-----------------------------------
Currently cube is modeled in the UI frontend layer. the service layer
accepts the model definition (in json format), do some checking and pass to
the next layer. I'm for fixing this in the UI frontend.

> suppose a metric column price is of type decimal (6,2), the sum aggregator of
> it might exceed the maximal of decimal (6,2). Currently for metric
> aggregators we inherite the column's type in hive. We should think auto
> expanding decimal type to decimal(18,4) (just an example) for such cases
