Abstract

The invention provides a data consistency implementation method and device and a storage medium. The method comprises the steps that when the data copying mode of a main database and the data copyingmode of a standby database are both preset modes, log data generated when the main database executes a current service are obtained from the main database, and the preset modes are a full-synchronouscopying mode or a semi-synchronous copying mode; and the log data is copied to a standby database before the main database submits the executed current service. Real-time synchronization of data between the main database and the standby database can be ensured, the data consistency between the main database and the standby database is improved, the availability of a financial service system is improved, the service continuity is improved, and the technical problems that in the prior art, the data consistency between the main database and the standby database cannot be guaranteed, consequently,the availability of the databases is reduced when the main database breaks down, and the continuity of financial services is affected are solved.

Description

technical field [0001] The present application relates to the financial field, and in particular to a method, device and storage medium for realizing data consistency. Background technique [0002] At present, MySQL database products have matured day by day. Since the data synchronization between the primary and secondary MySQL databases is asynchronous and logically replicated, the data consistency between the primary and secondary databases cannot be guaranteed. [0003] In the Internet scenario, in order to ensure the data consistency of the primary and secondary databases, it is usually regularly checked whether the data in the primary and secondary databases is consistent, and inconsistent data is repaired. However, this approach does not apply to financial services. The data inconsistency was discovered only after the later inspection and verification. At this time, the business may have been running for a period of time, and the business processing system may be run...
