摘　　要：为满足中老(中国—老挝)铁路磨万(磨丁—万象南)段(简称:中老铁路)客票系统建设需求,提升其可用性和稳定性,设计了中老铁路容灾数据同步系统。结合层次化服务设计思想,详细阐述了该系统的架构和功能,重点研究了数据容灾和应用容灾,以及数据压缩、消息治理、自动化切换等关键技术,解决了数据库与缓存间双写操作中代码高度依赖、高并发环境下数据同步效率低、故障恢复迟缓等难题,为中老铁路的数据缓存同步提供了稳定可靠的解决方案。In order to meet the demand for the construction of the passenger ticketing and reservation system of the Boten-Vientiane South section of the China-Laos railway(referred to as the China-Laos railway)and improve its availability and stability,this paper designed a disaster tolerance data synchronization system for the China-Laos railway.Combined with the idea of hierarchical service design,the paper described the architecture and functions of the system in detail,and focused on data disaster tolerance and application disaster tolerance,as well as key technologies such as data compression,message governance,and automatic switching.The system solves the problems such as high code dependency in the dual write operation between database and cache,low data synchronization efficiency and slow failure recovery in the highly concurrent environment,and provides a stable and reliable solution for the data cache synchronization of China-Laos railway.
