First, in this chapter we will use a few brief words to help you quickly understand what is redis, beginners do not have to get to the bottom
1 Redis Introduction
Remote Dictionary Server (Redis) is an open source use written in ANSI C, support network, based on the persistence of memory can log type, key-value database, and provides multi-lingual API
It is often called a data structure of the server, because the value may be a string value String, hashes the Map, the list List, and an ordered collection of the sorted set collection set and other types
2 Redis Features
2.1 Advantages:
1. To support a variety of data structures, such as String string, list doubly linked list, dict hash table, set set, set, etc sorting zset
2. Support persistence operations, and can be aof rdb data persistence to disk, data backup or data recovery operations, better means of preventing data loss.
3. Support for data replication via Replication,, can be replicated in real-time data synchronization via master-slave mechanism to support multi-level replication and incremental replication, master-slave mechanism is an important means Redis be HA (Hight Availability) of.
4. The single-process request, all the serial execution command, and delivers the data coherency problem without the need to consider
