Title:
CLUSTER QUORUM METHOD AND APPARATUS, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116661
Kind Code:
A1
Abstract:
Disclosed are a cluster quorum method and apparatus, an electronic device, and a computer-readable storage medium. The method comprises: obtaining a past voting set, and using the past voting set to obtain a first node number and a power supply condition; generating a quorum parameter according to the power supply condition by using the first node number; obtaining the current network topology, and determining whether the current network topology satisfies the quorum parameter; and if the quorum parameter is satisfied, providing a cluster service. According to the method, there is no need to ensure that nodes in a new network topology after a fault are the majority in an original cluster, such that the network topology can continue to work no matter how many nodes are comprised in the network topology while data consistency is guaranteed, thereby improving viability of a cluster.
