Abstract

The invention discloses a data synchronization method and device for heterogeneous databases and electronic equipment, and aims to improve the data synchronization efficiency between the heterogeneous databases. The method comprises the following steps: acquiring data operation information corresponding to data change information in a source database, wherein the data operation information comprises data for data operation and an execution sequence; performing conflict detection on an insertion operation in the data operations corresponding to the data change information to identify whether a primary key conflict exists between data aiming at the insertion operation and existing data in a target database or not; reconstructing the target insertion operation into a corresponding deletion operation and a new insertion operation on the basis of the data corresponding to the target insertion operation with the primary key conflict, so as to obtain reconstructed data operation information; and based on the reconstructed data operation information, executing corresponding data operation on the target database so as to synchronize the data change information to the target database.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data synchronization method, device and electronic equipment for heterogeneous databases. Background technique [0002] Any changes to the database are recorded in the logical log file as binary files. At present, data synchronization between heterogeneous databases is usually based on the synchronization of the logical log files of the source database, that is, the logical log files of the source database are parsed into corresponding data operations and sent to the consumer program at the data synchronization end. Execute the corresponding data operations on the target database in the sequence, so as to realize data synchronization between heterogeneous databases. [0003] Due to the unreliability of the transmission process, the consumer program needs to reconstruct all insertion operations to ensure the idempotency of the data. Obviously, this method has the pr...
