Problems solved by technology
[0002] Database cross-version upgrades usually use a version-by-version upgrade method. This solution is usually implemented in one operation process, including database version upgrades and storage engine switching. If problems occur during the upgrade process, it will increase the uncertainty of troubleshooting. At which stage did the problem occur; at the same time, it increases the complexity of the operation and the difficulty of troubleshooting

The embodiment of the invention discloses a database upgrading method and device. The method comprises the steps: firstly, deploying a database based on distributed file storage in a master-slave deployment mode, and obtaining a master library and a slave library; keeping a storage engine of the main library unchanged, and gradually upgrading a first version of the main library to a target version to obtain a current main library; configuring the version of the slave library as a target version, and newly adding a storage engine for storage engine switching for the slave library to obtain a current slave library; and finally, switching the storage engines of the current master library and the current slave library. The whole upgrading process of the database comprises two stages of version upgrading and storage engine switching, so that the complexity of database upgrading is reduced, the difficulty of troubleshooting in the upgrading process is reduced, and the technical problems of complicated operation in the upgrading process and high difficulty of troubleshooting in the upgrading process in related technologies are solved.
Description
technical field [0001] The present disclosure relates to the technical field of database upgrading, and in particular to a database upgrading method and device. Background technique [0002] Database cross-version upgrades usually use a version-by-version upgrade method. This solution is usually implemented in one operation process, including database version upgrades and storage engine switching. If problems occur during the upgrade process, it will increase the uncertainty of troubleshooting. At which stage did the problem occur; at the same time, it increases the complexity of the operation and the difficulty of troubleshooting. Contents of the invention [0003] The main purpose of the present disclosure is to provide a database upgrading method and device. [0004] In order to achieve the above object, according to the first aspect of the present disclosure, a database upgrade method is provided, including deploying a database based on distributed file storage in a m...
