配电网监测数据索引集群的分布缓存方法
Distributed Cache Method for Index Cluster of Distribution Network Monitoring Data
摘要
Abstract
Aimed at the problem that the response time in distribution network monitoring system is too long due to a rapid increase in distribution network monitoring data,a hot data part link list(HDPL)distributed cache method is pro-posed in this paper.By introducing cache technology and analyzing the limitations of the existing hot data link list(HDL)cache method,a novel HDPL cache method is proposed to improve cache management efficiency.Meanwhile,a preheated query is designed to realize a hot start for the index system,so as to improve the cache hit ratio of the index system.The monitoring data of one distribution network is taken as an example to verify the effectiveness of the pro-posed method.Results show that the proposed HDPL cache method and the designed preheated query can greatly re-duce the query time for the index cluster under different query conditions,effectively improving the query efficiency of distribution network monitoring data index cluster.关键词
