改进的key/value数据存储设计方案

Improvement of Key/Value Data Store Design

针对现有key/value缓存系统海量数据的访问速度慢,满足不了应用的需求,提出一种改进的key/value数据存储方案并将其应用于缓存系统中。通过小数据量存储方案的提出,及对rehash算法、rehash权重因子w的改进,十分有效地解决了hash冲突、rehash迁移数据导致的系统变慢问题,加快了缓存系统的速度,提高了缓存系统的命中率。

In the view of existing key/value caching system mass data access speed slow unable to meet the application requirements, put forward an improved key/value data storage scheme and applied it to the cache system. Put forward a small amout of data storage program and improved rehash algorithm ＆ the rehash of the weighting factor w, a effective solutions to a hash conflict, the rehash of migration data led to the system slows down, accelerated the speed of the cache system and improved the cache hit rate
