Example Embodiment

[0042] In order to solve the problem in the prior art that the distributed database cannot determine the data consistency before and after the data change, the present invention provides a method, device and related device for verifying data in a distributed database. The present invention compares the data to be verified before and after import. Whether the data check value of the changed data row is the same, or compare the number of rows of the data to be changed before and after the import and whether the sum of the data check value of the corresponding row number is the same, so that the data to be changed can be accurately determined before and after the change Consistency effectively solves the problem that distributed databases in the prior art cannot determine data consistency before and after data changes. The present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodime...

Abstract

The invention discloses a distributed database data verification method and device and a related device. According to the method and device and the related device, the consistency of to-be-changed data before and after the change is determined through comparing whether verification values of an appointed line of data in the to-be-changed data before and after import are consistent or not, so thatthe problem that distributed databases in the prior art cannot determine the data consistency before and after the data change is effectively solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and related device for verifying distributed database data. Background technique [0002] With the wide application of database technology and the continuous accumulation of online business data, especially the rapid development of Internet business, the amount of data is increasing day by day, and the performance of stand-alone databases has increasingly become the bottleneck of online business, and because distributed databases can provide high performance, Database services with large storage capacity and high concurrency can be quickly applied to various online business scenarios. [0003] However, the existing distributed databases cannot determine the consistency of data before and after data changes during data migration and data initialization, thus limiting the application range of distributed databases. Contents of the invention [0004] The p...
