Design And Implementation Of Distributed Users Online State System

User online state system,which is a sub module,is often used as a sub module in the practical application.It is designed to optimize the data storage structure,and fully consider the high concurrency,high request,high availability,load balancing,and achieve a more optimized online state system.This paper designs a distributed user online state system,which can achieve high performance,high availability,load balance,improve the user experience,improve the user experience.Research contents include the determination of system design criteria and design decisions,determine the system's test plan,model design,data storage structure design,and select the high performance NoSQL data;how to achieve portability,high availability,load balancing.The key issues to be resolved include the design of the system module,the realization of the module decoupling,the design of the architecture of the distributed system,the availability of the system,and the high availability of the system.
