摘要： 数据网格是一个典型的分布式系统,访问其中的广域分布的海量数据需要很大的时间开销。介绍GridDaen数据网格系统实现高速数据统一访问的Cache技术。GridDaen采用二级Cache机制,使用两个数据缓冲表来快速定位缓冲数据和控制缓冲数据访问,给出了各级Cache的数据替换算法,并提供了灵活的配置方法,可以将Cache与客户机、服务器独立分布,实现了Cache的可扩展性。

Abstract: Access to widely distributed massive data in data grid which is a typical distributed system spends a lot of times. This paper introduces cache technique to implement fast data uniform access in GridDaen data grid. GridDaen uses two-level cache, which adopts two cache-data tables to locate cache-data and control data access, designs replacing data algorithm in its cache, and provides a set of flexible config methods which can separate cache from client or server and implement scalable cache in client or server.
