云计算平台中对象存储的数据同步方法讨论摘要随着云计算的快速进展,以与数据产生速度的不断提高,各种云计算平台和应用对信息存储的要求也越来越高。包括亚马逊、谷歌和 IBM 在的很多互联网巨头都投入到对云存储系统的讨论中。本文通过分析 OpenStack 平台的云存储系统 Swift,在对该系统进行分析的基础上,了解云存储系统中对象存储技术的使用,以与对象存储系统中同步各类数据的方法。同时本文使用了一定的篇幅详细分析了 Swift 存储系统中客户端与系统的数据传输,并讨论了存储系统维护对象的一致性而进行的同步,基于此提出可配置副本存储方案在数据同步方面所需要进行的设计开发。在上述工作的基础上,通过修改 Swift 的部分源代码,调整系统的配置结构和业务逻辑,实现可配置副本的存储方案。最后,基于云存储系统的应用环境对设计的系统进行分析,讨论该系统在不同情况下的工作方式并给出系统 API 调用的方法示例,评估系统在实际应用环境中的表现。关键词: 云存储,对象存储,对象同步,一致性AbstractWith the rapid development of cloud computing, as well as the continuous improvement of the data generation, a variety of cloud computing platforms and applications for information storage requirements are also increasing. Many Internet giants, including Amazon, Google and IBM are put into the cloud storage system.In this paper, we analysis the OpenStack cloud storage platform system Swift.Based on analyzing the system, we try to understand the using of cloud storage system and object storage technology.At the same time, we use a detailed analysis of the data transmission and the client of the system in the Swift storage system, and research the synchronization for the sake of consistency maintenance of the object storage system. Then, we study the design of a configurable copy storage scheme for the data synchronization.On the basis of the above-mentioned work,we modify the Swift part of the source code, adjust the configuration of the system structure and business logi...
