Abstract

The invention is applicable to the technical field of distributed index clusters, and provides a method for solving cache failure of a mass data distributed index cluster, which comprises the following steps of: 1, screening a search manager to screen out hot data; 2, carrying out hotspot data correlation analysis on the screened hotspot data, and carrying out comprehensive sorting according to the correlation and search times; 3, analyzing the performance of the searcher, and calculating a difference value between preheating time spent by preheating query and a time gain effect brought by preheating query; 4, a preheating query statement is set, and the optimal number of optimal preheating queries is found through an experiment; and step 5, testing and setting time gains brought by the optimal preheating query number under different conditions. According to the method, the problem of system cache failure caused when the operation is submitted is solved, meanwhile, hot start of the system is achieved, cluster resources are greatly saved, and the cluster query speed is increased.

Description

technical field [0001] The invention belongs to the technical field of distributed index clusters, and in particular relates to a method for solving the cache invalidation of massive data distributed index clusters. Background technique [0002] With the continuous increase of the scale of high-speed railways in my country, the use of four electrical equipment such as traction power supply system, railway power system, railway communication signal power supply and catenary isolation switch, as well as the use of 6C system, make the data collected by the inspection and monitoring system increase sharply. The volume of data has exceeded the terabyte level, which makes the effective storage of valuable data a new problem. It is difficult for traditional terabyte-level databases to meet the storage requirements, and the growth rate of data has far exceeded the growth of computer performance. How to quickly process the massive data of the distribution network and propose a rapid ...
