Redis is an emerging NoSQL data caching component, similar to Memcache, but with more functionality than memcache. First, both Redis and Memcache are memory-based, so read and write speeds are very fast. However, Memcache only supports simple

Redis is document-based, and it's difficult for nosql to deal with relationships. For example, people can blog, blogs can be categorized. According to the traditional SQL, the user table and the classification table are the main table, the blog

I/O operations are an essential part of every system. In addition, I/O operations may also affect the system efficiency to a certain extent. Today, I learned how to handle I/O in redis. Similarly, redis also encapsulates an I/O layer in its own
