Abstract

The invention relates to the technical field of electronics, in particular to a data migration verification method and apparatus. The method comprises the steps of calculating each row of migrated data in a process of migrating the data from an A end to a B end to obtain an identifier corresponding to each row of data; migrating the identifier and the row of data corresponding to the identifier to the B end; calculating a sum of identifiers corresponding to all rows of data in the migration process to obtain a first value, and calculating a sum of identifiers corresponding to all rows of data at the B end to obtain a second value; and when the first value is equal to the second value, indicating that data migration verification is passed. An embodiment of the invention furthermore provides the apparatus which executes the method. The method and the apparatus have extremely high working efficiency for data verification of the problems of row loss, row data repetition and the like in the data migration process.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a method and device for verifying data migration. Background technique [0002] Importing a large amount of data from a file into a database (DB) is currently a common business scenario for data import, especially in Internet application scenarios, after the data is imported, it is necessary to verify the correctness of the imported data to ensure the integrity of the data in the database sex and correctness. The usual practice in the prior art is to retrieve the data from the database, and then check it with the data in the file item by item. During the check, the following problems often occur, and the following problems are particularly serious in the scenario of massive data import: [0003] Assuming that the file has a total of N lines, and the data imported into the database is M lines, read the data line by line from the file, retrieve the database, and comp...
