Abstract

The embodiment of the invention provides a data processing method and device. The method comprises the steps that the initial number of virtual database instances in a database instance is acquired; according to the initial number of the virtual database instances, the target number of the virtual database instances is configured, the initial number of the virtual database instances is equal to 2m, m is larger than or equal to 0, the target number of the virtual database instances is 2n times of the initial number, and n is a positive integer; according to the target number of the virtual database instances, the corresponding relation between the virtual tokens and the virtual database instances is updated, and the virtual tokens are integer ranging from 0 to 2n-1, the number of the virtual tokens corresponding to the virtual database instances is the same; and data is migrated based on the corresponding relation between the virtual token and the table name according to the updated corresponding relation. According to the data processing method and device provided by the embodiment of the invention, the database instance can be expanded into a plurality of virtual database instances to realize the cluster function of the database.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data processing method and device. Background technique [0002] Some existing specific databases can only provide a predetermined number of database instances and do not support cluster configuration, such as the open source Influxdb database. Influxdb database is a time-series database that can be used to store time-related data. However, with the increase of database application requirements, in the face of huge reading and writing pressure, it is necessary to use a predetermined number of database instances to realize the cluster function. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the a...
