This invention discloses a data synchronization method, apparatus, device, storage medium, and computer program product. The method, applied to a master node, includes: responding to a data object write request and generating a metadata sequence containing index information of each data segment; constructing a replication control flow based on this sequence to describe transmission order constraints and completion conditions; sending the metadata sequence to slave nodes; sending the corresponding data segments while satisfying the order constraints; and sending a synchronization completion flag when the transmission status meets the completion conditions. This invention combines the metadata sequence with the replication control flow, transforming the traditional content-based driving approach into a unified scheduling control based on metadata. Through pre-planning the transmission order and a judgment mechanism, it achieves structured control of the synchronization process, eliminating the need for overall processing of complete objects, significantly improving the execution efficiency and controllability of data synchronization, and reducing the uncertainty of handling complex objects.

A control processing method, apparatus, device, and storage medium belong to the field of computer and internet technology. The method includes: displaying a user interface, where a first operation control is displayed at a first control position on the user interface; in response to the first operation control being copied, displaying a copied control of the first operation control in the user interface, the copied control inheriting the function set of the first control position, the function set including control functions corresponding to various states; and in response to the copied control being triggered, executing the control function corresponding to a first state, where the first state is one of the multiple states currently satisfied. By copying the first operation control at the first control position on the user interface to obtain a copied control, and the copied control inheriting the function set of the first control position, the copied control can maintain consistent functional performance and operation mode with the first operation control in various states, thus truly realizing a logically inherited control copying function.
