Abstract

The invention discloses a real-time data migration method. The method includes: exporting and loading full data from a source database to a target database; during the process of data loading, recording customer information with data changes; The information provides data synchronization transaction through the transaction system of the source database; according to the data synchronization transaction, real-time data synchronization is performed through the transaction system of the target database. The method of the present invention performs real-time data synchronization on changed customer information through data synchronization transactions during data migration, and can ensure that real-time transactions of customers are not affected during data migration.

Description

technical field [0001] The present invention relates to the field of computers, more specifically, to a method, device and storage medium for real-time data migration between different databases in a computer system. Background technique [0002] In the business system, with the continuous development of the business and the rapid increase of customers, outdated database versions or data table involvement will become the bottleneck restricting business development. The single-instance deployment of the database may have the risk of a single point of failure; the unreasonable design of the database sub-table and sub-database may cause resource contention when the business is busy, resulting in low system concurrency. When the above situation occurs, it is necessary to consider adjusting the existing database design and performing data migration. [0003] During the process of data migration, the real-time trading system cannot stop external services. In the prior art, the O...
