Problems solved by technology

[0003] The database partition table has greatly improved the management and access efficiency of large database tables, but there are also some problems when using partition tables. For example, as the data grows, it is necessary to back up and delete historical data exceeding a certain period. Currently, manual operations are used. There may be misoperations, low efficiency, non-standard backups, and even backup failures

Abstract

The invention discloses a partition table backup method and device, electronic equipment and a storage medium. Relates to the technical field of databases. The method comprises the steps that a partition maintenance configuration table is read, and a first partition table needing to be automatically maintained is determined according to the partition maintenance configuration table; determining partitions exceeding a preset retention period of the first partition table according to the partition maintenance configuration table, and determining backup tables corresponding to the partitions; and replacing the data of the partitions into the backup table, and deleting the partitions. Through the technical scheme of the invention, the partition table can be backed up simply, efficiently and accurately.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of databases, and in particular, relate to a partition table backup method, device, electronic equipment, and storage medium. Background technique [0002] In order to meet the data management needs of large tables in the database, the large tables are converted into small data and divided into smaller, better-manageable segments. These segments are called partitions, and the corresponding tables are called partition tables. The partitions are physically stored independently of each other, but logically share the relevant attributes of the table. Each partition can be managed independently, and can function independently without relying on other partitions, which has the advantages of easy management and use. [0003] The database partition table has greatly improved the management and access efficiency of large database tables, but there are also some problems when using partition tab...
