Abstract

The invention relates to a data comparison method and device, computer equipment and a storage medium. The data comparison method comprises the steps of obtaining task configuration information of a comparison task, wherein the task configuration information comprises a source data connection identifier, a target data connection identifier and a target thread number; establishing connection with asource database according to the source data connection identifier, and obtaining source data from the source database; establishing connection with a target database according to the target data connection identifier, and obtaining target data from the target database; extracting data identifiers in the source data and the target data; performing hash operation on the data identifier, and grouping hash results according to the number of target threads; determining a target thread corresponding to each group; and calling a plurality of target threads to perform concurrent comparison on the source data and the target data corresponding to the hash results belonging to the same group. By adopting the data comparison method, the data comparison efficiency can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data comparison method, device, computer equipment and storage medium. Background technique [0002] Based on business development requirements, enterprises often need to synchronize or migrate source data from one database to another. The synchronized or migrated data can be referred to as target data. In order to ensure the integrity of the source data, it is necessary to compare the consistency of the source data and the target data during data synchronization and migration. The traditional data comparison method is mainly to compare multiple pieces of data in two isomorphic databases one by one based on DBLink (Database Link, database link), which makes the data comparison efficiency low. Contents of the invention [0003] Based on this, it is necessary to provide a data comparison method, device, computer equipment and storage medium capable of improving da...
