Remarks

FixedPivotData was specially designed for querying large cubes with minimal memory consuption / initialization time. Typical slicing operation that iterates through all cube values with GetEnumerator is performed with minimal possible memory usage and almost fast as PivotData. On the first indexer access dictionary-based indexes are initialized (this may take some time) and after that individual values are also returned fast.
