Research on a Method of Using Whole Sort Timestamp Vector Method in Massive Data Update Conflicts
Abstract
Data consistency consists of strong consistency and weak consistency. Strong consistency ensures that the data replicas keep consistent at any time, but it limits system availability, weak consistency ensures the data replicas keep consistent at last that greatly increases system availability, but it can not keep concurrent modification timely. Replication is the key technology of massive data consistency. The article, according to the characteristic of massive data, based on the existing method of maintaining the consistency of massive data, improves the method that solves the problem of update conflicts with timestamp vector of whole sort in data replication. It greatly improves the system availability which uses timestamp vector to solve the problem of update conflicts.
