Node scheduling method, node switching method, node coordinating method, corresponding device, equipment and medium thereof

Abstract

The invention discloses a node scheduling method, a node switching method, a node coordinating method, a corresponding device, equipment and a medium thereof. The node scheduling method comprises thesteps: in response to a node query request, obtaining a specified task type, querying an access entry of a corresponding service node from a node database, and enabling the access entry to serve as the feedback of the request, wherein each service node is used for scheduling an execution node for the corresponding type of task; when the service node corresponding to the task type cannot be queriedin the node database, in response to a role switching instruction of the execution node, storing an access entry of the execution node and the task type as data records of the node database so as toupdate the execution node to the service node; and monitoring connection states of all the service nodes, and clearing the data records of the service nodes from the node database after the service nodes are disconnected. According to the multi-center distributed task scheduling system constructed in the technical scheme of the invention, various types of tasks can be scheduled more efficiently and orderly.

Description

technical field [0001] The present application relates to the field of computer networks, in particular to a node scheduling, handover and coordination method, and related devices, equipment and non-volatile storage media corresponding to these methods. Background technique [0002] The scale of the systems of major Internet companies is increasing, and the number of business-related tasks is increasing and becoming more and more complex, especially in a distributed environment. When there are multiple business systems, each business system has processing tasks. Therefore, it is necessary to have a task platform for unified management and scheduling of the tasks of each business system, that is, a distributed task scheduling system, so as to respond to a large number of task processing requests of various types of business systems in a timely manner and meet the task processing requirements of corresponding businesses. [0003] At present, the execution logic of most distrib...

Problems solved by technology

[0004] First of all, the dispatching center configuration dispatching node adopted in the prior art, even if the dispatching center adopts a high-availability solution, because there is only a single dispatching center structure, that is, there is only one dispatching center node that provides dispatching services, if If the dispatching center node has a failure such as downtime, the system will be unavailable for a period of time, and it will take a long time to return to an available state, resulting in a large number of tasks that cannot be executed, resulting in various types of services that cannot be provided to users.

[0005] Secondly, the processing method related to task execution in the prior art does not consider the availability of execution nodes, and directly preempts the same task by multiple execution nodes unconditionally, so it is easy to cause task conflicts, causing multiple execution nodes to repeatedly execute the same task. tasks, and because the task loads of different execution nodes are unbalanced, it is actually impossible to achieve greater processing efficiency reasonably and efficiently
