Redis is a representative of the Key-value database in the open source NoSQL, developed in C language, followed by BSD License. Supports memory, disk persistence storage, and it has a very rich data type, including strings, linked lists, ordered collections, and so on. High availability comes with a master-slave archit

Memcached: High-performance distributed cache database Key-value storage mode (HASHMAP) Data persistence is not supported, all data is lost after server shutdown C developed, based on the Libevent library, available on most linux,bsd,solaris, as well as in Windows and other OS The client implements the software in a number of languages: C

The rich data structure makes the design of Redis very interesting. Unlike relational databases, Dev and DBAs require deep communication, review each line of SQL statements, and unlike memcached, do not require DBA involvement. Redis DBAs need to be familiar with data structures and understand usage scenarios. Here are some common examples of the KV database to t

Label:Add by Zhj: A record of a relational database table can be mapped to a hash type in Redis, in fact, the database record is the key value pair. This saves memory by using fewer keys than the keys in this article, because each key
