Data modeling and application design with Redis
Taking advantage of Redis' data structures
Redis ships with tools and types that are intended to make development easier. It has structures to simplify tasks, such as maintaining a queue of sequential events, or lists of unique items (ordered or unordered). Chances are that one of Redis' delivered types will suit how your application needs to store or manage data.
