Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, hyperloglogs, bitmaps, streams and spatial indexes. The Redis project is mainly developed by Salvatore Sanfilippo and is currently sponsored by Redis Labs. Redis was initially released in 10th of May 2009.

Other than that it includes o...
