Problems solved by technology

[0002] With the rapid development of Internet technology, a large amount of data is generated every moment. How to query the desired data from the massive data is particularly critical, but the current data query system does not support real-time data query within the refresh interval. Query, the data written in the refresh interval cannot be queried, and the real-time performance is not high

Abstract

The present application discloses a distributed real-time data query method, cluster, system and storage medium. The method is applied to a distributed query system. The distributed query system includes a gateway cluster and at least one regional cluster connected to the gateway cluster. The regional cluster Including a first storage cluster and a second storage cluster connected to each other, the method includes: receiving a first request signaling sent by an external device, wherein the first request signaling includes query time and external device information; During the preset refresh time period corresponding to the second storage cluster, query the data corresponding to the external device information from the corresponding first storage cluster to obtain a first result set; generate a query result set based on the first result set, and store the query results The set is returned to the external device; the first storage cluster is used to cache the written data in real time, and the second storage cluster is used to store the written data in all time periods. In the above manner, the present application can realize real-time query.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, cluster, system and storage medium for distributed real-time data query. Background technique [0002] With the rapid development of Internet technology, a large amount of data is generated every moment. How to query the desired data from the massive data is particularly critical. However, the current data query system does not support real-time data within the refresh interval. Query, the data written within the refresh interval cannot be queried, and the real-time performance is not high. SUMMARY OF THE INVENTION [0003] The present application provides a distributed real-time data query method, cluster, system and storage medium, which can realize real-time query. [0004] In order to solve the above technical problems, the technical solution adopted in this application is to provide a distributed real-time data query method, which is applied to a...
