Asynchronous task scheduling method, device and system and electronic equipment

Abstract

The invention discloses an asynchronous task scheduling method, device and system and electronic equipment. The asynchronous task scheduling method comprises setting a value of a scheduling parameter for each asynchronous task to be scheduled, wherein the scheduling parameter is a parameter which is used for scheduling retrieval in the scheduling process and shows the execution characteristic of the asynchronous task; setting a corresponding retrieval parameter in dependence on the scheduling demand; retrieving an asynchronous task the scheduling parameter of which is matched with the retrieval parameter from the asynchronous tasks to be scheduled stored in an asynchronous task database in dependence on the retrieval parameter; and calling and executing the asynchronous task which is obtained through retrieval and satisfies the retrieval parameter demand. By employing the above method, the problem that an execution node interacts with a database frequently, the task scheduling sequence and demand cannot be guaranteed, and therefore the asynchronous task scheduling accuracy is low, and the execution of the asynchronous task is slow can be solved. Through the above method, a plurality of scheduling modes of the asynchronous task can be achieved by means of simple parameter setting.

Description

technical field [0001] The application relates to the technical field of distributed data processing, in particular to an asynchronous task scheduling method, an asynchronous task scheduling device, and an asynchronous task scheduling system; the application also relates to an electronic device. Background technique [0002] With the rapid development of the Internet, the scale of servers on which the Internet depends is also becoming larger and larger. And with the continuous expansion of user services, asynchronous tasks often require the use of distributed network storage systems. Therefore, how to manage, maintain and schedule these asynchronous tasks in cross-machine applications has become an urgent problem to be solved. [0003] The traditional asynchronous task scheduling method includes: directly calling the asynchronous task from the database to the execution node. It can be seen that the traditional asynchronous task scheduling method has the following limitatio...

AI Technical Summary

Problems solved by technology

It can be seen that the traditional asynchronous task scheduling method has the following limitations: the execution node interacts frequently with the database; it involves network communication and wastes traffic; it cannot guarantee the order and requirements of task scheduling, resulting in low accuracy of asynchronous task scheduling. Execution of asynchronous tasks is slow

[0004] Even if the traditional asynchronous task scheduling method can meet the scheduling of tens of millions of tasks, it cannot realize the efficient execution and allocation of asynchronous tasks, often resulting in idle resources and exhaustion of some resources, which brings a lot of trouble when scheduling asynchronous tasks. extremely limited
