author's continuous addition of new features, the follow-up speed of the corresponding third-party clients may not be able to catch up, sometimes you may need to make some modifications on the basis of a third-party client for better use. It is not difficult to see from the above that when we do not want data to be kicked out, or need more data types except key/value, or need to implement the function, using redis is more suitable than using memcach

Redis is a high-performance Key-value database. The emergence of Redis, to a large extent, compensates for the lack of memcached such keyvalue storage, in some cases can be a good complement to the relational database. It provides the Python,ruby,erlang,php,java client, which is very convenient to use.Redis uses a single-threaded IO multiplexing model, which encapsulates a simple Aeevent event processing fr

Introduction to Redis:First, IntroductionRedis is an open source, Key-value database that is written in C and that supports network interaction and can be persisted based on memory. Redis source code is very simple, as long as there is time to see rectification C language, to see the source of Redis can read 50-60%. The current largest cluster of Redis should be

For such functions, you need to understand their implementation principles and understand In addition to storage, apsaradb for Redis also provides some other functions, such as aggregate computing,
