: This article mainly introduces a simple php Cache method using redis. if you are interested in the PHP Tutorial, please refer to it. The cache method described here is relatively simple. The following is a rough idea: Example: A list cache example can be cached for 1 minute because the real-time requirement of list

Problem Description Recently we used spring cache + Redis to do caching. Under high concurrency the @cacheable annotation returns a null content. Look at the source code, in the use of annotations to get the cache, the Rediscache get method will first determine whether the key exists, and then to get the value. There's a copper leak, and when thread 1 judges tha

500ms, when the small white realized that the program needs to be optimized.This time the small white teacher came, the teacher said, these articles list data, in a short period will not change too big, why not to cache it up? This can be removed from memory every time, without having to access the database every time.The project architecture is made up of the simplestAdded the cache layer:In this way, the

The caching method described here is relatively simple, the following is the approximate idea :Example:A list cache example, because the list data real-time requirements are not high, can be cached for 1 minutes.Approximate idea:According to the URL of the request to determine:1. The requested URL hash is recorded in Redis and the data in Redis is returned direct

Suppose dal uses php as an example. I used to use php to operate mysql separately. Now I need to squeeze the server and consider adding a redis instance. However, I am confused about the access policies of the two data sources. I hope to help me sort it out. It is better to explain it with pseudo code. Thank you. Suppose dal uses php as an example.

1. Be sure to set the maximum cache size and set the cache policyIf you do not set the maximum cache, the Redis crashes when the new data is added, if the maximum memory is exceeded!Setting mode: MaxMemory 1GBAfter logging in using REDIS-CLI, use the Info command to view the

Adding a Redis cache using Springboot needs to be introduced in the Pom fileOur support for adding the cache requires two dependencies, one for the Springboot internal cache configuration, and the other for our Redis cache.Configuring the

A: Introduction to RedisRedis is fully open source free, adheres to the BSD protocol and is a high-performance Key-value database.Redis and other Key-value cache products have the following three features: Redis supports data persistence, which saves data in memory on disk and can be loaded again for use when restarting. Redis not only supports simpl

1. Who decided to take the Redis cache? Of course it's mybatis.MyBatis in the default implementation of data deletion and modification function, here to use the cache AhAnd it's mybatis. This ORM framework uses a caching mechanism, and MyBatis has a two-tier cache by default! So, you only need to configure
