Zusammenfassung:The invention provides a heterogeneous database migration method, a heterogeneous database migration device and a storage medium, which are used for solving the technical problems of low migration efficiency, instability and the like of a heterogeneous database. According to the method, the source tables are grouped based on the dependency relationship between the source tables and the data volume, and the exporting step of the source database and the importing step of the source database to the target database are executed in parallel through the multiple migration tasks. The migrated data does not fall to the ground in the data export and import processes, and is directly imported in batches through the memory cache, so that the migration efficiency is improved. Under the condition thatmigration is interrupted, the migration offset during interruption can be found, incremental migration is conducted based on the offset during re-migration, and the migration stability is improved. 本公开提供一种异构数据库迁移方法、装置及存储介质,用于
