摘要
在智能电网环境下,录波数据具有广域、全景、海量和可靠的特征,传统的存储硬件采用磁盘阵列,数据库管理软件采用关系数据库系统的方法由于系统扩展性差、成本高、可靠性低,难以适应要求。本文提出了一种基于Hadoop的录波数据分布式存储与访问的新方法,并将其与传统方法的访问速度进行了对比,证明了新方法的高效性。
In the smart grid,recorded date is wide,panoramic,reliable and mass. The old way is using ER database management system based on disk arrays, which leads the poor system scalability, high cost, and low reliability, those are all really hard to match the requirements. Compared the access speed with the traditional method, the method of the access and recorded data based on the Hadoop with distributed storages It is proposed more efficiently.
