-------------------------------
To be frank, this does not sound like a useful feature. However, it has no harm
behind the dictionary builder extension point. I'm not negative to merge the
patch.
> AppendTrieDictionary support not global

> Currently, AppendTrieDictionary only support global dict, which means the
> dict will grow continuously. But for the cube doesn't have Partition Date
> Column and the cube doesn't need aggregate query across segments, we could
> build AppendTrieDictionary from empty dict every time.
