[Denali CTP3] Analysis Services New Feature : Scalable String Storage

As you may know, both dimension's attributes and distinct count measures can be of string data type. During processing, Analysis Services reads data and put them into individual stores organized by attributes in case of dimensions or by measures groups/partitions for cubes.

The file format of those stores differ to adapt to the type of the data located inside. By default, until now, string stores couldn't exceed the 4GB file size limit.
