Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] see figure 1 , figure 1 is a flow chart of a task scheduling execution method provided by an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0027] Step 101. Obtain a first list of tasks to be executed at intervals of a first preset time period.

[0028] Wherein, the above-mentioned first task list is the tasks that need to be scheduled and executed in the current period, such as business data rep...

Abstract

The invention provides a task scheduling execution method and device, and the method comprises the steps: obtaining a to-be-executed first task list every first preset duration; determining a second task list preferentially executed in the first task list according to a depth-first search algorithm; and scheduling execution resources to execute the tasks in the second task list. According to the embodiment of the invention, the method comprises the steps: obtaining a to-be-executed first task list every first preset duration; according to the method, the second task list which is executed preferentially is determined according to the depth-first search algorithm, and the execution resources are scheduled preferentially to execute the determined second task list, so that core emergency tasks with high execution priorities of the execution resources can be scheduled preferentially in the high-concurrency time period of the tasks, and the timeliness of task scheduling execution is improved.

Description

technical field [0001] The present invention relates to the application field of big data platforms, in particular to a task scheduling execution method and device. Background technique [0002] Under the big data platform, in order to ensure the effective execution of tasks in the platform, the platform usually builds a task scheduling platform to manage the tasks. The task scheduling system precisely controls the execution of tasks based on scheduling parameters such as inter-task dependencies, resource constraints, and priorities. [0003] The general-purpose task scheduling platform has the ability to execute tasks of different types of tasks, and realizes the controllable execution of tasks according to the task scheduling parameters configured for implementation: dependencies, priorities, estimated resource occupancy, and operating cycles. In consideration of versatility and scalability, the scheduling platform usually consists of services such as task dispatching and...
