Problems solved by technology

[0004] However, the current data consistency detection method has the following problems: when the user's business is frequent, the database throughput is very large, and a lock table operation will cause many businesses related to the table in the business to fail to proceed normally, affecting the normal operation of the user. business
When the amount of data in the user's business table is large, the time for consistency detection will increase significantly, which will cause the database lock to not be released for a long time, and also affect th

Abstract

The invention relates to a database data consistency detection method and device, a medium and electronic equipment, and the method comprises the steps: obtaining a first database connection of a source database, configuring an isolation level as a serialization isolation level, and closing automatic submission; starting a data detection transaction in the first database connection; acquiring total data of the source database at the current moment and first database log information; acquiring synchronized second database log information in a target synchronization system of the target database; based on the first database log information and the second database log information, obtaining a corresponding synchronization log from a source end synchronization system of the source database; analyzing the synchronization log into an SQL statement to be executed in a target database; acquiring total data of the target database after the execution is finished; performing data consistency detection based on the total data of the target database and the total data of the source database; and submitting a data detection transaction after the data consistency detection is completed.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of database technology, and in particular, to a database data consistency detection method, a database data consistency detection device, a computer-readable storage medium and electronic equipment for realizing the database data consistency detection method. Background technique [0002] In the business scenario of applying a database, data is synchronized from the source database to the target database, and there are many links in the middle that may cause some data errors or missing. Therefore, it is necessary to check whether the source and target data are consistent during data synchronization. [0003] In related technologies, when comparing whether the data of the source end and the target end are consistent, it is usually to first lock the related business tables of the source database and the target database, and then perform comparison to realize data consistency detection. [000...
