1. First-level caching is the form of storing data in a local cache (low operating hit): Scope of interrelated persistent object caches: Transaction scope, each transaction has a separate first-level cache concurrency Access policy: Because each transaction has a separate first-level cache without concurrency problems, there is no need to provide concurrent acces

Tags: number of times on-line speed exists developer fixed program Targe base Cache penetration refers to querying a nonexistent data, the cache layer and the storage layer are not hit, but for fault-tolerant considerations, if the data from the storage layer is not written to the cache layer, 11-3 shows the entire process is divided into the following 3 steps:

The thinkphp F method can only be used to cache simple data types and does not support expiration and cache objects. The S () cache method supports the validity period, also known as the dynamic caching method. This article is a small series of daily finishing about thinkphp caching methods, the thinkphp cache method i

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

Level 1 cache, level 2 cache, and lazy loading (transfer) in Hibernate, and level 1 cache in hibernate1. Why cache? Hibernate uses cache to reduce the number of accesses to the database, thus improving the execution efficiency of hibernate. There are two types of

conceptual interpretation of 一、一级 cache level two cache (1) First-level caching is the session-level cache, a session to do a query operation, it will put the results of this operation in a cache, if the short time this Session (must be the same session) and do the same operation, then hibernate directly from the firs

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

Evaluate the differences between thinkphp data cache, static cache, and query cache. If the browser saves openid, can it use cache to replace sessioncookie? What is the difference between thinkphp data cache, static cache, and que

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

Http://zeroq.me/p/279 I. cache penetration When cache is used in projects, the app first checks whether the cache exists. If cache content exists, the app directly queries the database and then caches the query result and returns it. At this time, if a piece of data we query does not exist in the
