摘　　要：为了解决物联网异构数据的存储问题,该文提出了一种混合技术存储方案。针对结构化数据存储,该文基于MySQL分布式数据库和Redis缓存,设计了结构化数据的存储方案;对于图片等非结构化数据,通过FastDFS分布式文件系统进行管理,使用Redis缓存保存文件的索引映射关系并实现快读热点数据的功能。最后对系统进行测试,测试结果表明该方案实现了性能目标。In order to solve the storage problem of heterogeneous data in the Internet of Things,this paper proposes a hybrid technology storage scheme.For structured data storage,this paper designs a structured data storage scheme based on MySQL distributed database and Redis cache;for unstructured data such as pictures,it is managed through the FastDFS distributed file system,and the Redis cache is used to store the index mapping of the file relationship and realize the function of fast reading hot data.Finally,the system is tested,and the test results show that the solution in this paper has achieved the performance goal.
