Abstract

The invention provides a data consistency verification method, device, electronic equipment and readable storage medium, and relates to the field of computer technology. After the same sorting process, take out the first elements of the two record lists and compare their unique identifier sizes until there are no remaining elements in either list, and put the first element with the largest unique identifier back into the original queue. The first element with the smallest unique identifier is classified into the verification result table to realize data consistency verification for each element in the two record lists. The verification result table includes: only the elements in the first record list The first result of the , the second result of only elements in the second record list. The problem of difficult data verification in the prior art when the data in the target database and the source database are not exactly the same is solved.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a data consistency checking method, device, electronic equipment and readable storage medium. Background technique [0002] At present, data consistency verification is mostly used for database synchronization or migration. After the synchronization or migration is completed, the data consistency between the source database and the target database is verified. The verification method is divided into data verification and log file verification. Data verification is verified by comparing the verification sum (such as MD5 value) of each record. Log file verification is synchronized by comparing transaction logs Data consistency; and both methods need to verify whether the data is completely consistent. [0003] The existing data consistency verification method needs to verify whether the data is completely consistent, which cannot meet the situation ...
