Liu Xin-song · Jisuanji gongcheng · 2007
Cost reduction of write operation in database transaction is important in distributed database system design.The paper presents a new update mechanism,named cooperate cache-based distributed database update mechanism(CCDDU).It reduces disk access cost in database transaction by means of cooperative caching pool constructed with physical memory among the servers.This paper describes cooperate cache-based distributed database update mechanism,focusing on how the mechanism improves transaction performance and its availability.
