The Swiss Army Knife of caching, and the dominant caching data store presently. Can be used and "put in front" of nearly anything to increase its speed. Used for both persistent and non-persistent storage. Has high flexibility in its data structures (Sets, Sorted Sets, Hashes, Lists, Strings, Bit Arrays, HyperLogLogs, Geospatial Indexes)*Redislabs

Is highly efficient for medium and small sizes, less efficient for very large.
