Abstract: Embodiments of the present application provide a data synchronization method and apparatus. The method includes: acquiring source data from a source database; converting the source data into to-be-synchronized data matching a data meta format of a target database; synchronizing the to-be-synchronized data to the target database; determining whether dirty data has been detected during the synchronization; and in response to the dirty data being detected during the synchronization, skipping the detected dirty data to continue with synchronizing the to-be-synchronized data.
