> currently, when user set dozens of precise count distinct metrics in one
> cube, we put all the count distinct metrics column in one columnFamily. Which
> result in HBase scan become slow because the one {{KeyValue}} is too big. we
> could set more columnFamily to speed up the HBase scan in this scenario.
