Task scheduling system and method and server

Abstract

The invention provides a task scheduling system and method and a server, and the system comprises a first task distribution module and a plurality of task execution modules. The first task distribution module is in communication connection with the plurality of task execution modules; the first task distribution module is used for storing a to-be-executed task; and the plurality of task executionmodules are used for obtaining the to-be-executed task from the first task distribution module, and executing the to-be-executed task through the task execution module obtaining the to-be-executed task. The to-be-executed task is obtained from the first task distribution module through the plurality of task execution modules, compared with the mode that the task queues distribute all the tasks toall the work nodes according to the arrangement sequence of the work nodes, the task execution modules in the mode actively obtain the tasks, so that the task distribution flexibility is improved, thetask execution modules can obtain the tasks according to the work states of the task execution modules, and the task distribution rationality is improved.

Description

technical field [0001] The present invention relates to the technical field of big data processing, in particular to a task scheduling system, method and server. Background technique [0002] The task scheduling system in the related art usually stores the tasks in the database, and the scheduling node obtains the tasks from the database, and then sends the obtained tasks to the task queue, and the task queue assigns each task to each working node, and the assignment In the process of tasks, they are usually assigned according to the order in which the working nodes are arranged, which leads to poor flexibility of task assignment and makes it difficult to allocate tasks reasonably. Contents of the invention [0003] The purpose of the present invention is to provide a task scheduling system, method and server to improve the flexibility and rationality of task allocation. [0004] In a first aspect, an embodiment of the present invention provides a task scheduling system, ...
