When we use the cache, whether it is Redis or memcached, we basically encounter the following three issues: Cache-through-cache concurrency cache invalidation First, the cache penetrates Note:What's wrong with the above three graphs? Our use of caching in our projects is

Preface To design a caching system, the problem that has to be considered is: cache penetration, cache breakdown and failure of avalanche effect.Cache Penetration Cache penetration means querying a data that does not exist, because the cache is written passively when it is not hit, and for fault tolerance, if no data

Level 1 cache and level 2 Cache A. level 1 cache (Session-level cache): load the same object twice in a session. During load, Hibernate first searches for the object in the session cache, load data to the database if not found. Therefore, when an object is loaded twice in th

In "MVC cache 01, use controller cache or data layer cache", you can set useful cache time in the data layer. However, this is not "intelligent". It is often expected to invalidate the cache and load new data when it is modified or created. □Ideas 1. the

Several caches, need to use the front-end configuration, plus a backend instance withFragment cache:Public Function indexaction () { //render page $this->view->settemplateafter (' common '); Cache fragments Front-end configuration $frontcache = new \phalcon\cache\frontend\output (Array ( "lifetime" = 86400 );Back-end processing $

The cache memory is a temporary memory located between the CPU and memory. It has much smaller capacity than the memory, but the switching speed is much faster than the memory. The emergence of cache mainly aims to solve the conflict between the CPU operation speed and the memory read/write speed, because the CPU operation speed is much faster than the memory read/write speed, this will take the CPU a long

Preface I believe most developers are familiar with caching.

In the previous section, we implemented the random cache algorithm and the FIFO cache algorithm. Now, we will continue to implement two other famous cache algorithms: LFU and LRU. Once again, this code is only used for demonstration. If you want to use it in an application, you need to add additional work.Let's look at the implementation of the LFU
