Abstract

The embodiment of this specification provides a data migration method and device, wherein the method is used to migrate the state data of the source database to the target database, and the state data is dynamically updated data; the method includes: a first application The service receives a data update request requesting to update the state data of the source database; opens the transaction template to record the update data corresponding to this update operation, the update data includes: the latest value of the state data, and synchronizes the update data to the message center. After receiving the successful synchronization notification returned by the message center, the first application service submits the update data recorded in the transaction template to the source database, so that the source database updates the corresponding state data; the message center sends the update data to the second application service , the second application service sends the update data to the target database.

Description

technical field [0001] The present disclosure relates to the technical field of databases, in particular to a data migration method and device. Background technique [0002] Data migration is a very common scenario, which is a method of migrating data from one storage medium to another. For example, a company originally adopted commercial storage equipment, which was costly and difficult to maintain. After developing the corresponding storage equipment by itself, the data needs to be migrated. Migration needs to minimize the impact on existing businesses, and data accuracy must also be ensured. The accuracy requirements for financial data are extremely high, and any data loss or error is not allowed. [0003] For flow-type data, such as account details, etc., since the data will no longer change, the old data can be directly relocated and then the database can be switched. However, for state data such as user balance information, since the data is changing all the time, t...
