Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0040] Existing database query methods can easily lead to computationally intensive query requests occupying all computing resources, eventually resulting in increased response time of the entire system and decreased system throughput. To solve this technical problem, in some embodiments of the present application, a distributed query system is provid...

Abstract

The embodiment of the invention provides a distributed query system and method, equipment and a storage medium. In the embodiment of the invention, the distributed query system comprises front-end nodes and computing nodes. The front-end nodes can determine the query type to which the received query request belongs, and add the query type to which the query request belongs to at least one query task corresponding to the query request. Thus, the computing nodes can execute the query task in a mode matched with the query type according to the query type to which the query request carried by thereceived query task belongs. Furthermore, when the query type to which the query request belongs is the first query type, the computing node can preferentially execute the received query task, so thatthe system blockage degree can be reduced, and the system response time and the system throughput can be improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a distributed query system, query method, device, and storage medium. Background technique [0002] In today's information age, the application and research of information data has become a trend. Based on its advantages, databases are widely used in data storage, management, maintenance and query. [0003] With the development of big data, database systems often need to provide data of different dimensions for different users. Due to the different query requirements of users, the database system may receive query requests of various calculation amounts. The current database query method can easily lead to computationally intensive query requests occupying all computing resources, which eventually leads to an increase in the response time of the entire system and a decrease in system throughput. Contents of the invention [0004] Various aspects of the p...
