-MultiDimensionalIndexer
-=======
-The **\Magento\Framework\MultiDimensionalIndexer** library provides functionality of multi-dimension index creation and
-handling.
-
-Library introduces a set of extension points which split monolithic index by specified Dimension (Scope), creating 
-independent index (i.e. dedicated MySQL table) per each Dimension. Along with that library provides index name 
-resolving mechanism based on provided scope. The Multi-Dimension indexes introduced for the sake of data scalability
-and ability to reindex data in the scope of particular Dimension only.
-
-Aliasing mechanism guarantees zero downtime to make Front-End responsive while Full Reindex being processed.
