How to Quickly Complete MySQL Data Difference Comparison?

In the modern business environment, databases are important tools for enterprises to store core data, and MySQL, as one of the most popular relational database management systems, is widely used in various industries. In scenarios such as disaster recovery, data migration, and backup recovery, to ensure the consistency of data between two or more ends, it is usually necessary to perform consistency comparison of the data.

The traditional method of data comparison "manual sampling" usually requires a series of cumbersome processes, including exporting data sets, comparing data sets, and writing SQL to modify inconsistencies. It's fine when the amount of data is not large, but in the case of large data volume and complex database structure, it may cause serious business failures. For example, when a company migrates a large amount of order data, manual sampling does not find the inconsistency in the results. After the business switch, it leads to abnormalities in customer order information, which is fatal for the company's brand and credit impact. Therefore, the automation of data comparison is the trend of the times.

Insufficiencies of Data Comparison Tools on the Market

Performance Issues: Most tools are based on local computer resources for data comparison, which cannot handle a large amount of data comparison and have slower comparison speeds.
Functional Limitations: Only support specific types of data sources, which cannot meet all user needs.
Operating System Compatibility: The support for mainstream operating systems is not comprehensive, causing difficulties for users.
Expensive: Some commercial tools provide good performance and user experience, but they are often expensive and not suitable for small and micro enterprises.
