随着调控云运行数据平台历史数据存储规模持续增长,对历史数据访问的高性能、高可靠性、易扩展需求日益增加。结合业务需求,在分析缓存应用技术的基础上,提出了基于Redis的运行数据平台分布式缓存框架,研究了运行数据缓存的高效存储模型、高速访问、高可用管理等关键技术。实验结果表明,在读写性能、可靠性、可扩展性等多个方面,可满足各类业务应用对运行数据平台历史数据管理与访问的要求。
As the continuous growth of historical data storage scale on the operation data platform of the dispatching and control cloud
the demand for high performance
high reliability and easy expansion of historical data access is increasing. Combined with the business requirements and based on the analysis of cache application technologies
a Redis based distributed cache framework of operation data platforms is proposed
and the key technologies in the operation data cache such as efficient storage models
high-speed access and high availability management are studied. The experimental results show that it can meet the requirements of various business applications for historical data management and access of operation data platforms in terms of read-write performance
reliability and scalability.
