First, overview: The previous blogs focused on commands related to Redis data types, such as String, List, Set, hashes, and Sorted-set. These commands all have one thing in common, that is, all operations are for the value associated with the key.
ObjectiveRedis is a common memory-based Key-value database that is more advanced than memcache and supports a variety of data structures, efficiently and quickly. Redis makes it easy to solve high-concurrency data access problems, and it's good to
