Data synchronization method and device, electronic equipment and storage medium

The embodiment of the invention discloses a data synchronization method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an original operation log of a source database, and analyzing the original operation log to obtain table operation information of the source database; adjusting configuration information of the current data extraction task according to the table operation information to obtain a target data extraction task; executing the target data extraction task to synchronize data in the source database to a data warehouse; and synchronizing the data in the data warehouse to each data mart. The data extraction task can be adjusted based on the operation log of the source database, data synchronization is achieved by executing the adjusted data extraction task, the whole data synchronization process is completed in an automatic mode, manual participation is reduced, the labor cost is reduced, the data synchronization efficiency and accuracy are improved
