About Redis

Redis is a key-value storage System , the official site Http://redis.io

1. similar to memcached, but supports data persistence

2. support for more value types , in addition to string (string), also support hash, lists (linked list), sets (collection) and sorted sets (ordered collection) several data types

The 3.redis uses two file formats: full-volume data (RDB) and incremental request (AOF). The full data format is to write the in-memory data to disk for the next read of the file to load. The incremental request file serializes the in-memory data into an operation request for reading the file for replay to get the data
