memcached monitoring

Today, I saw a memcached on the Internet as the hibernate level-2 distributed cache. I felt very interested. I tried it and it felt pretty good. I recommend it to you. Http://code.google.com/p/hibernate-memcached/The latest version is 1.0, supporting hibernate3.3. The following describes how to use it:Hibernate-memcached must support the following class libraries

First, the concept　　Memcached is a free and open source, high performance, distributed memory object caching system.Memcached is a memory-based Key-value store used to store arbitrary data (strings, objects, and so on) of small pairs. This data can be a database call, an API call, or a result of a page render.The general purpose is to reduce the number of database accesses by caching database query results to improve the speed and scalability of dynam

After the record times out, the client can no longer see the record (invisible, Transparent), and its storage space can be reused.Lazy ExpirationMemcached internally does not monitor whether the record is out of date, but instead looks at the tim

) network Factors Network factors refer to whether MySQL and Memcached are in the same IDC, and whether the network performance between them is good. The better the network performance, the faster the speed. The locally deployed Memcached can reduce network overhead. 4) inserted data volume The size of the inserted data volume includes two aspects: the size of each record inserted into MySQL, and the size

We're off duty today. How to install, start, and uninstall memcached in the Windows operating system: 1, download the relevant software: Download Address:http://download.csdn.net/download/wangshuxuncom/8249501; 2, extract the compressed files obtained, you will get a folder called "Memcached-1.2.6-win32-bin", the folder will be copied to the appropriate location (such as copy to the C packing directory); 3,

Memcached is an open-source, high-performance, distributed memory object cache system that can be used in various cache scenarios. Its main purpose is to accelerate Web applications by reducing database access. It is a memory-based "key-Value Pair" storage that stores direct data from database calls, API calls, or page reference results, such as strings and objects. You need to describe the difference between him and memcache. mencache is a module of

Everyone is familiar with memcached. The introduction from Baidu encyclopedia is as follows: Memcached is a high-performance distributed memory object Cache System for dynamic web applications to reduce database load. It caches data and objects in the memory to reduce the number of times the database is read, so as to provide dynamic, database-driven website speed. Me
