Abstract

The invention discloses a data migration method and device and is used for solving the problem that in the prior art, a data migration mode is relatively low in migration efficiency and bad influences are caused in user service. The method comprises on the basis of a preset timing interval, periodically performing the following steps of determining a current migration vernier value, dividing a plurality of continuous time intervals starting from the current migration vernier value, updating the current migration vernier value to the maximum time in the plurality of time intervals, wherein the migration vernier value is initially the minimum time of the newest modification time of data records in a source database; for each divided time interval, generating a migration task corresponding to the time interval, wherein the migration task is used for migrating the data records of which newest modification time currently belongs to the time interval, in the data records of the source database to a target database; and performing the generated migration tasks concurrently.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data migration method and device. Background technique [0002] With the rapid development of the Internet and computer technology, more and more businesses can be conducted online. [0003] Users can submit business requests to the business system through the Internet, and the business system performs corresponding business processing according to the received business requests, and returns the business processing results to the users. Data is stored in the database of the business system in the form of data records. [0004] In practical applications, in order to improve business processing capabilities, business systems often need to be updated. When the original business system is to be upgraded to a new business system, if the database used by the new business system (called: target database) is different from the database used by the original business system (ca...
