Abstract

The invention relates to a database cluster upgrading method, device, equipment and a storage medium. The database cluster upgrading method comprises the steps of establishing upgrading processes withthe same number as to-be-upgraded cluster nodes in an original database cluster; obtaining a full snapshot file and real-time data of each to-be-upgraded cluster node in parallel through each upgrading process, analyzing the full snapshot file of each to-be-upgraded cluster node in parallel, and sending the analyzed full snapshot file to a preset target database cluster, synchronizing the real-time data of each to-be-upgraded cluster node to a preset target database cluster in parallel; and when it is detected that each to-be-upgraded cluster node satisfies a data synchronization completion condition, switching the client traffic of the original database cluster to a preset target database cluster, the database version in the target database cluster being higher than the database versionin the original database cluster. According to the embodiment of the invention, the upgrading of the database cluster can be realized in real time at a high speed and across large versions.

Description

Technical field [0001] The invention relates to the technical field of computers, in particular to a database cluster upgrading method, device, equipment and storage medium. technical background [0002] Since its open source in 2011, Remote Dictionary Server (Redis) has become the first choice for caching databases in the Internet and some traditional IT enterprises because of its strong performance, good stability, rich functions and ease of use. In recent years, Redis has a big version upgrade every year, which not only fixes some problems of the previous version, but also adds many excellent features. Many projects are looking forward to using these features. [0003] In the practical application of Redis, data are often stored in the Redis cluster. When upgrading versions, how to upgrade Redis clusters in real time, at high speed and across large versions becomes a necessary condition for effective management of Redis clusters. [0004] Among related technologies, the common...
