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 pre-execution tasks of a plurality of subsequent tasks, one task being selected from the pre-execution tasks of each subsequent task as a pre-trigger task; sequentially executing the pre-execution tasks, and if the execution is successful and the pre-execution tasks are pre-trigger tasks, adding subsequent tasks of the pre-execution tasks into a waiting queue; judging whether all the front execution tasks of all the subsequent tasks in the waiting queue are completed or not, recording the subsequent tasks of which all the front execution tasks are completed as to-be-executed subsequent tasks, and adding the to-be-executed subsequent tasks into the to-be-executed queue; and determining an execution number, and executing the execution number of subsequent tasks in the to-be-executed queue. According to the technical scheme, the task scheduling efficiency and accuracy can be improved.

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...
