redis distributed cache

What is memcached? Memcached is a software developed by Brad fitzpatric, danga interactive under livejournal. It has become an important factor in improving the scalability of Web applications among many services such as Mixi, hatena, Facebook, Vox, and livejournal. Many Web applications save data to RDBMS. The application server reads data from the data and displays it in the browser. However, as the data volume increases and access is concentrated, the burden on RDBMS increases, the databa

Distributed cache server, since the use of data caching is obviously to be efficient to obtain data, large-capacity storage data. In order to cache large amounts of data and to obtain data efficiently, the distributed cache database should solve the problem that the data can

Overview Velocity is a distributed cache solution launched by Microsoft. It provides support for developing scalable, available, and high-performance applications and caches various types of data, such as CLR objects, XML, binary data, and cache servers in cluster mode.

understood to replace the servlet set of Session management, do not rely on the container, without changing the code. If you are using spring-session, use the Spring-data-redis set of connection pools, prefect, but only if you have to use the spring framework. As for Shiro, it is a very mature, powerful and easy-to-use security framework that costs more to learn than spring-session. let's look at the implementation of the second approach It is import

At work, there are often problems with resource access conflicts in a distributed environment, such as a store's inventory number processing, or an atomic operation of an event, which requires ensuring that only one thread accesses or processes resources within a certain time period.So now there are many distributed lock solutions on the Internet, such as database, MemCache, Zoopkeeper and so on.This time,

The most typical and most important bug is that if there are a lot of processes in IIS, there is not enough memory to use the garbage collection mechanism, it will cause the session to be lost. The workaround is that you can store the session in a sate server or SQL Ser

Original article: http://topic.csdn.net/u/20080722/22/3a63114f-31ea-4174-ba9f-0c0d0c8cb293.html Why cache? If you ask this question, it means you are a newbie. After all, the database throughput is limited, and 5000 reads and writes per second are amazing. If you do not need to cache, assume that there are 100 database operations on a page, the concurrent databases of 50 users are closed, so that up to 50*3
