Embodiment Construction

[0034] In the prior art, task scheduling is usually performed based on secondary development of open source software or commercial software. However, since the current scheduling method based on open source software adopts the scheduling method based on task flow, such as oozie, azkaban, etc., it is necessary to define the logical relationship between each task in the task flow. This method has high coupling between different task flows. When the number of tasks and task relationships increase in complexity, it is very difficult to define the task flow accurately and clearly. If the task flow cannot be accurately defined, it is easy to make mistakes in the scheduling process. In addition, scheduling methods based on open source software usually only provide core task scheduling functions, and lack auxiliary task development, task relationship organization, task status maintenance, task monitoring, task governance, service monitoring, log downloading, and many other capabilities...

Abstract

A task scheduling method and device, a storage medium, and a terminal, the method comprising: determining a plurality of pre-execution tasks of subsequent tasks, wherein one task is selected from the pre-execution tasks of each subsequent task as a pre-trigger task ; Execute the pre-execution tasks in turn, if the execution is successful, and the pre-execution tasks are pre-trigger tasks, then add the subsequent tasks of the pre-execution tasks to the waiting queue; determine each follow-up task in the waiting queue Whether all the pre-execution tasks of the task have been completed, the follow-up tasks that all the pre-execution tasks have been completed are recorded as follow-up tasks to be executed, and the follow-up tasks to be executed are added to the queue to be executed; Specifies the number of subsequent tasks to be executed in the queue to be executed. The technical solution of the invention can improve the efficiency and accuracy of task scheduling.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a task scheduling method and device, a storage medium, and a terminal. Background technique [0002] With the rapid development of the securities trading market, the types of transaction business and the amount of data to be processed are also increasing. As an enterprise-level data storage and computing center, the batch processing task relationship of the data platform is becoming more and more complex, timeliness and correctness. The higher and higher requirements lead to smaller and smaller processing time windows and emergency time windows left for the data platform, all of which put forward higher requirements on the efficiency, high availability and ease of maintenance of the batch processing architecture of the data platform. Require. [0003] In the prior art, task scheduling is usually performed based on secondary development of open source software or commer...
