Redis (2009) is an open-source in-memory database project released in May 2009 implementing a distributed, in-memory key-value store with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, hyperloglogs, bitmaps and spatial indexes
.
Redis is mostly single threaded, or double-threaded when it rewrites the AOF log.[1]
Redis is also provided as a service in different Cloud providers such as ElastiCache from Amazon Web Services, Azure Cache from Microsoft Azure, Alibaba Cloud offers ApsaraDB and Google Cloud Memorystore.
