基于分布式数据库的海洋动力环境数据云存储
Cloud storage of ocean dynamics environment data
摘要
Abstract
Considering spatial-temporal characteristics of the ocean dynamics environment data,the paper presents a cloud data management based on the distributed database,including a distributed spatial-temporal data sharding schema and a spatial-temporal index.The cloud management realizes physical distributed storage and logical integral structure of data,which improves the efficiency of data retrieval.Taking an example of ocean dynamics environment data in the South China Sea,to compute wave height-period scatter graph of 40 years,the cloud storage system takes less than 10 seconds while the files system takes about 2 minutes.关键词
