I. OverviewThe cache (Caching) can store information that is often used so that it is immediately available every time it is needed.Common Cache Database:Redis uses memory storage (in-memory) for non-relational databases, strings, lists, collections, hash lists, ordered collections, and each data type has its own exclusive commands.There are also bulk operations (bulk operation) and incomplete (partial) tra
store, both key and value are serialized using the Redis Serializer (serializer). Spring Data Redis provides a number of such serializers, including:
Generictostringserializer: Serialization using the Spring transformation service;
Jacksonjsonredisserializer: Using Jackson 1, serialize the object to JSON;

Integration example of Redis cache + SpringThe article integrating spring 4 (including mvc, context, orm) + mybatis 3 example) briefly introduces the integration of Spring MVC, IOC, and MyBatis ORM in the latest version and declarative transaction processing. This article will introduce the integration of Redis cache +
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
What is Redis?Redis is a TCP server that supports request/response protocols. In Redis, the request is completed using the following steps:
The client sends a query to the server and reads from the socket, usually in a blocking manner, for the server response.
The server processes the command and sends the response back to the client.

Aof method will append each received write command to the file through the write function (default is appendonly. aof), when redis restarts, it re-executes the write command stored in the file to recreate the entire database content in the memory.

First, the question
The amount of data per query is enormous and requires the server to respond to user requests more quickly.
Second, the solution

How php operates redis Cache
In addition to memcache, a commonly used php operation class library, we may also be very familiar with memory cache, Which is redis. We will share this php technical article with you, this is about how to use php to operate the redis memory
The Redis Cache server is a keyvalue database that reads 110000 s and writes 81000 s. it is fast because it is a memory operation, common usage is to store user tokens, text message verification codes, and other official websites to show that Redis itself does not have a Windows version, Microsoft officially developed a Windows-based
only be judged by ourselves
Then we use Redis to put the verification code into Redis and give an expiration time to solve the problem well

3, take the result of two times to compare the address:Found that two are not the same object, yes, yes. If you are using Ehcache, then the memory address of the two will be the same. That's because the caching mechanism used by Redis and Ehcache is different. Ehcache is based on the local computer's memory usage cac
