redis usage

Redis is currently the NoSQL field of the popular fried chicken, it is like a Swiss Army knife, small, sharp, practical, especially suitable for the use of traditional relational database difficult to solve problems. But Redis is not a silver bullet, there are many problems that are suitable for it, but there are many problems that are not suitable for it to solve. In addition,

In the use of Redis process, we found that a lot of redis different from the memcached, but also different from the characteristics of MySQL.(This article mainly discusses Redis is not enabled for VM support) 1.

: The internal implementation of set is a value that is always null hashmap, which is actually calculated by hashing the way to fast weight, which is also set to provide a judge whether a member is within the cause of the collection.

is a data structure server because Redis supports complex data features such as list, set, and so on. Different interpretations of the role of Redis determine how you use Redis.Internet data is currently used in two different ways to store, relational database or key value. But these internet services do not belong to these two types of data, such as the user's relationship in the social platform, it is a
