Abstract

The invention discloses a database processing method, a database processing device, a storage medium and a terminal, which relate to the technical field of data processing, and mainly aim to solve theproblem of low data processing efficiency during capacity expansion of an existing database. The database processing method mainly comprises the steps of: determining a first data storage corresponding relationship of original data nodes by utilizing the number of the original data nodes and the number of preset virtual nodes, and determining a second data storage corresponding relationship of current data nodes by utilizing the number of the current data nodes and the number of the preset virtual nodes; according to the first data storage corresponding relationship and the second data storage corresponding relationship, determining a mapping relationship of data storage from the original data nodes to the current data nodes; and storing the target data in the original data nodes into thecorresponding current data nodes according to the mapping relationship.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a database processing method and device, a storage medium, and a terminal. Background technique [0002] With the advent of the era of big data, the scale of data storage is also gradually increasing, especially for the processing of a single data node in a relational database, the pressure becomes extremely high. [0003] At present, the existing database targets data in the form of sub-tables, and the database is divided into several small tables in the form of a large table. The data is distributed and stored in different tables according to specific algorithms. The number of nodes will cause all the data in the database to be redistributed and stored every time a new node is added, and adding node data that is an even multiple of the original number of nodes will also cause more than half of the data to be migrated, resulting in unnecessary waste of data resources. In...
