Data update and access method and its device, cluster system

Abstract

The embodiment of the present application provides a data update and access method and its device, and a cluster system. The data update method includes: determining the target cluster node associated with the data update; judging whether the target cluster node has the starting conditions for data update, and if , the off-hook operation is performed on the target cluster node; after the off-hook operation, the data on the target cluster node is updated, so as to update the data on the cluster nodes in the above-mentioned cluster and further provide effective data access plan.

Description

technical field [0001] The embodiments of the present application relate to the technical field of the Internet, and in particular to a data updating and accessing method and device thereof, and a cluster system. 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. Cluster configurations are used to improve availability and scalability. Especially some computing-intensive applications, such as: weather forecast, nuclear test simulation, etc., require computers to have strong computing and processing capabilities. With the existing technology, even ordinary large-scale machines are difficult to perform calculations. At this time, computer cluster technology is generally used to concentrate the computing power of dozens or even hundreds of computers to meet the requirements...
