Abstract

The invention provides a leader election method and device based on multiple copies, equipment and a storage medium, and relates to the technical field of communication. The method can be applied to a target cluster, and comprises the following steps: acquiring a plurality of resource observation vectors at the current moment through each first application copy; according to the plurality of resource observation vectors at the current moment and a preset predictor, obtaining a predicted submission delay sum corresponding to each first application copy at the current moment; and according to the predicted submission delay sum corresponding to each first application copy at the current moment, determining a first target leader application copy in the plurality of first application copies at the current moment. According to the method, the predicted submission delay sum corresponding to each first application copy at the current moment is quickly obtained, so that the first target leader application copy can be quickly elected from the plurality of first application copies at the current moment, and the method has the characteristics of simple election mode and high election efficiency.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a multi-replica-based leader election method, device, device and storage medium. Background technique [0002] A cluster is a group of independent computers interconnected by a high-speed network that form a group and are managed as a single system. When a client interacts with the cluster, the cluster behaves like a stand-alone server. [0003] Currently, in order to enhance the reliability of the cluster, the applications in the cluster are generally deployed in the form of multiple copies to tolerate downtime or distributed faults. Among them, in order to ensure the consistency of data in multiple application copies, the leader in multiple application copies is often determined based on the Raft algorithm, so that based on the application leader can ensure that the client requests are sorted in the ordered log and the The request is forwarded to other co...
