Concurrency Control Mechanism of SDD-1: A System for Distributed Databases (The General Case)

摘要

SDD-1, a System for Distributed Databases, is a distributed database system being developed by CCA. SDD-1 permits data to be stored redundantly at several database sites in order to enhance the reliability and responsiveness of the system and to facilitate upwards scaling of system capacity. This paper describes the algorithm used by SDD-1 for updating that is stored redundantly. (Author)
