摘要
Abstract
A novel lock scheme applied in distributed systems is proposed in order to fulfill the requirement of huge data throughput. The lock structure refines the granularity of data coverage and allows data sharing in (he premise of data consistency while the lock localization algorithm decreases the time to took up lock objects. These methodologies are evaluated in terms of throughput benchmark and lock collision ratio, and simulation result demonstrates that with these optimizations the storage layer can provide high-performance random access to data retrieval requests from upper layer.关键词
