Problems solved by technology

[0017] 1. Using the same interface as the application will affect the performance of the distributed database system, and the verification work is also harmful to the online environment
[0018] 2. The application and verification use the same interface, and the distributed database does not support a specific verification method, and the verification of correctness is not sufficient

Abstract

The invention relates to the field of communication, and discloses a method and system for verifying the data of a distributed database in real time. The data of the distributed database is distributed in N data nodes. The method comprises the following steps: after operating the distributed database, if the operation causes the data in the N data nodes to change, obtaining the changed data and synchronizing the changed data to a verification database independent of the N data nodes by a database incremental replication platform; and querying the verification database and verifying whether the operation carried out on the distributed database obtains a correct result. According to the method and system disclosed in the invention, the verification database is added, and the distributed database incremental replication platform is utilized to synchronize the updating data in the distributed database in the verification database, so that when the number of the data nodes changes or the algorithm for distributing the data on different data nodes is adjusted, the verification logic is not influenced and the online environment is not damaged.

Description

technical field [0001] The invention relates to the communication field, in particular to a distributed database data verification technology. Background technique [0002] With the development of cloud computing, the application of distributed database systems is becoming more and more common. In the application scenarios of distributed databases, how to verify the data correctness of distributed database systems, especially the systems that are providing services, has important practical significance. [0003] A common implementation is this: [0004] In a distributed database, the records of the same logical table will be distributed among multiple data nodes according to the hash distribution of the primary key. When it is necessary to verify the correctness of data in a distributed database system, there are usually the following two solutions: [0005] 1. Query and summarize each database node one by one, and finally form the summary data of the logical table, so as...
