In the original: Talking about Redis application scenarioFirst, the problem of mysql+memcached architectureThe actual MySQL is suitable for massive data storage, through the memcached to load hot data to the cache, speed up access, many companies have used such a structure, but with the increasing volume of business data, and the continuous growth of traffic, we encounter a lot of problems:1) MySQL needs to continue to disassemble the table, memcached

key-value pairs, and the time complexity of the lookup is irrelevant to the number of elements, and the hash table locates the elements by calculating the hash code value to locate the element's position and thus directly accessing the element, so the time complexity of the hash table lookup is O (1).How to be in.

replication is used together;The function of sharding is the distributed storage of data, and the function of master-slave replication is to provide backup for each shard node and increase data security.Note: The deployment of the Sina Redis cluster uses this scheme, and the use of Sina Redis is described in the blog before the big cc:The application of Redis in

capacity: Existing relational solutions cannot support Google's massive data storage;The NoSQL advantage is mainly reflected in the following points:1. Simple extension: typical example is Cassandra, because its architecture is similar to the classic peer-to, so it can easily add new nodes to expand the cluster;2. Fast Read and write: The main example is Redis, because of its simple logic, and pure memory
