Abstract: Aiming at the problem that a large amount of data in the system leads to slow data retrieval and lack of realtime, a flight delay visualization system based on elasticsearch(ES)- Redis is designed. This paper fully integrates the advantages of MySQL, ES and Redis, the flight data statistics is realized combining statistical query function of MySQL and the rich visual interface of Echarts. The real-time data retrieval is realized by ES and Redis, and the data processing speed of ES-Redis is more than 10 times that of MySQL. The Hybrid algorithm is used to realize the cache replacement of ES-Redis query mode, further improving the response speed of the system.

Key words: data real-time retrieval, flight delay statistics, cache replacement, elasticsearch(ES), Redis
