摘　　要：提出Redis数据库的分布式扩展机制并引入新的Key过期处理策略,构建了能够满足大规模数据应用场景下的缓存系统。经布署在广东等地系统的运行结果表明,该动态分布式缓存系统解决了原有计量采集系统中计量记录入库性能差的问题,能够满足海量数据的处理需求,具有高效、可靠、扩展方便的特点,对于构造提高关系数据库事务型操作能力的缓存系统具有指导意义。Based on Redis database, this thesis introduces a distributed extension mechanism and newKey overdue processing strategies. Meanwhile, a cache system which can be applied to big data isconstructed. The operation of the systems deployed in different places like Guangdong show that thisdynamic distributed cache system has successfully handled the performance bottlenecks existing in the oldmetering collection system and met the demands of big data processing. Thus, featuring high efficiency,good reliability and convenient extension, this system has exerted conductive significance on constructinga cache system which can improve the transactional operational capability of relational database.
