Redis Quick Start

Address: http://laoding.me/2010/08/redis-quick-start.html

Redis is an advanced key-value database. It is similar to memcached, but data can be persistent and supports a wide range of data types. There are strings, linked lists, sets, and ordered sets. Allows you to compute, merge, and merge sets (difference) on the server side. It also supports multiple sorting functions. So redis can also be seen as a data structure server.

All redis data is stored in the memory and then asynchronously stored to the disk (this is called the "semi-persistent mode "); you can also write every data change to an append only file (AOF) (this is called "Full persistence mode ").
