Abstract

The invention provides a data management method and device, and the method comprises the steps of obtaining an identification value of data when the data is requested to be written or read; determining a database group corresponding to the identification value, wherein each database group is used for storing data of which the identification value is within a preset range corresponding to the database group; calculating to obtain a remainder obtained by dividing the identification value by a preset target value corresponding to the database group; determining a database having a preset corresponding relationship with the remainder from the database group; and responding to the write operation or read operation of the data in the database. After the corresponding database group is determined based on the storage range, the data is ensured to uniformly fall into a plurality of databases of the database group in a modulo mode, and the hot spot problem is effectively avoided. Moreover, another database group can be directly expanded during capacity expansion, the number of databases and storage tables of other database groups is not influenced, and normal access of previously stored data is ensured.

Description

technical field [0001] The present application relates to the technical field of data management, in particular to a data management method and device. Background technique [0002] As the amount of business data increases, the amount of data stored and accessed in the database is also increasing. In the prior art, one storage table in the database is usually divided into multiple storage tables by means of table subdivision, so as to reduce the data volume of a single storage table, thereby reducing data query time and improving data access efficiency. And through the way of sub-database, the database is divided into multiple databases, so as to realize concurrent access. [0003] In the prior art, there are usually two storage methods based on sub-tables and sub-databases. One is based on the hash modulo method, which determines the storage location of the data by dividing the remainder of the identification value of the data by the total number of databases or storage t...
