Abstract:Aiming at the problems of difficult expansion and single point failure of meteorological data storage,this paper establishes a distributed meteorological data storage system by using distributed relational database,distributed analytical database and distributed tabular database.By comparing and analyzing the difference of access performance between distributed database and traditional database,it is found that the access time of distributed database is significantly higher than that of traditional database.The distributed Xugu database can complete real-time data storage and data access through the data service interface during the expansion period,and the real-time business is not affected,which can effectively meet the requirements of real-time meteorological data service.
