stupid method is also very practical. The result of the lookup is the redis_reply_string defined above in the Hiredis/read.h excerpt section as follows #define REDIS_REPLY_STRING 1 #define Redis_reply_array 2 #define Redis_reply_integer 3 #define Redis_ Reply_nil 4 #define REDIS_REPLY_STATUS 5 #define REDIS_REPLY_ERROR 6 The values returned are distinguished by these macro enumerations. Actually here basically about the Redis interface t

Redis (Remote Dictionary Server) is an open-source (BSD-licensed), in-memory data structure storage system that can be used as a database, cache, and message middleware. It supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered set), and hash (hash type). Redis supports master-slave synchronization. D

Redis is used as the cache in the project and memcache is not yet used. There are two main considerations: redis's rich data structure, its hash, list, set, and Strin with rich functions Redis is used as the cache in the project and memcache is not yet used.

Django Analysis Using redis Cache Server, djangoredis I haven't updated it for a long time. I have been busy with a project during this time. Today I will record a technology that is frequently used. Redis is familiar to everyone. Like memcached, redis is a high-performance key-value database. As for what is a

With the development of Redis, more and more architectures have replaced memcached as the cache server, which has several outstanding features:1. In addition to hash, sorted Set, list and other data structures are provided.2. Can be persisted to disk3. Support Cluster (3.0)It has the same performance and memcached, and with the popular other components (such as queues) will also use

In the previous article we analyzed the first level cache, level two cache related source code and basic principles, today we share the MyBatis level two cache and Redis combination, of course MyBatis two cache can also and Ehcache, Memcache, Oscache, Hazelcast used in combi

Redis cache failure story to start with the expire command, expire allows the user to specify a time-out for a key, and the value corresponding to the key will be erased after that time. This article mainly on the basis of the analysis of Redis source code to stand on the Redis designer's perspective to consider the pr

First, the purpose of caching the home page is not to improve performance, but to reduce database access pressure and effectively delay the arrival of database I/O bottlenecks. There are many ways to implement the home page cache, but since Redis is used in the project to cache database reads and writes, you can also cache
