Problems solved by technology
However, in the existing technology, when a task needs to be executed regularly in the cluster environment, it will be limited by the current cluster environment, causing the scheduled task to be executed repeatedly, or the fault tolerance of the cluster cannot be used, or even though the actual business operation has achieved deduplication But all instances under the cluster are used at the same time
[0003] Moreover, in the existing technology, the frequency of scheduling services needs to be particularly high, such as scheduling every 100 milliseconds, but due to network request delays, the request has not yet reached the business cluster after 100 milliseconds, resulting in task execution frequency not meeting expectations
If there are many similar scheduled tasks, it will greatly increase the number of network requests of the cluster and increase the network pressure of the cluster

The invention discloses a task scheduling method, computing equipment and a storage medium. The task scheduling method comprises the following steps: acquiring cluster information of a server cluster; constructing a target task; selecting a first node from the server cluster according to cluster information, and sending a target task to the first node; setting a detection frequency, and checking whether the first node has a fault according to the detection frequency; and if the first node has a fault, selecting a second node from other nodes in the server cluster according to the cluster information, and sending the target task to the second node, so that the second node communicates with the data server according to the execution frequency to execute the target task. According to the method, the server cluster does not need to be called through a network when the target task is executed every time, the task server sets the execution frequency, the server cluster can execute the target task according to the execution frequency, and service calling failure and repeated calling caused by network delay are avoided.
Description
technical field [0001] The invention relates to the field of server clusters, in particular to a task scheduling method, computing equipment and storage media. Background technique [0002] With the development of cloud computing technology, server clusters are used more and more widely, and many enterprises have begun to use server clusters to efficiently provide services. Clustering is a popular technology used to provide high availability and scalability services while supporting fault tolerance. However, in the existing technology, when a task needs to be executed regularly in the cluster environment, it will be limited by the current cluster environment, causing the scheduled task to be executed repeatedly, or the fault tolerance of the cluster cannot be used, or even though the actual business operation has achieved deduplication But all instances under the cluster are used at the same time. [0003] And in the existing technology, the scheduling service frequency is...
