ReasonOne of the reasons for today's slow access to a project is that it is slow to read Oracle, the amount of data is small, the configuration table is ignored, and the business table is 380,000 records. One solution is to use the cache.So the question is, which caching framework is good?EhcacheThe project has been using it, but the version may be a bit low. It's really handy, just get a jar bag on the line. Java's preferred.MemcachedWrite in C, more trouble, to install. The data that is integr

This article describes the implementation of the Redis cache class definition and use of PHP. Share to everyone for your reference, as follows: Php+redis Cache Class

The newly developed system needs to control the GC thread that recycles the cache at every moment and only one is running, which can cause the system to crash if there are multiple threads running concurrently. If only one JVM process is so good, simply use the Synchronized keyword. But my system is going to be deployed on multiple servers, on each server, on more than one instance. And synchronized is only useful in a single process. Consider using t

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 cache tool library. Php redis

Tags: Understanding data ring Why increase access speed disk resolution list first of all, we know that MySQL is persistent storage, stored in the disk, retrieval, will involve a certain IO, in order to solve the bottleneck, so there is a cache, such as the current use of the most memcached (referred to as MC). First, the user accesses the MC, if not hit, to access MySQL, and then like memory and hard disk, the data copied to the MC part of the

I. Introduction to RedisRedis 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 multiple types of data structures such as string (strings), hash (hashes), list (lists), set (sets), ordered set (sorted sets) with Range query, bitmaps, h Yperloglogs and geo-spatial (geospatial) Index RADIUS query. Redis has bui

Memcached and Redis have the same point: All are stored in the form of key-value pairs to store the data, popular speaking is a big HashtableThe cached data is present in the content Key-valueDifferent points:Memcached:1, a key corresponding value must be serialized through the client into a binary stream storage byte[] (disadvantage, because the serialization of deserialization consumes a large CPU)2, a key corresponding to the maximum value can only

Distributed caching, can solve the single server memory can not be unlimited expansion of the bottleneck. In the application of distributed caching, multiple client contention issues are encountered. This time, need to use a distributed lock, the client has access to the lock to operate permissions. Memcached and Redis are common distributed cache-building schemes, and the following are examples of implemen
