DATA SYNCHRONIZATION METHOD AND APPARATUS OF DISTRIBUTED SYSTEM, MEDIUM, AND ELECTRONIC DEVICE

Embodiments of this application provide a data synchronization method and apparatus in a distributed system, a computer-readable medium, and an electronic device. The method includes: obtaining historical data synchronization information of adjacent nodes connected to a target node and determining selection weight values of the adjacent nodes according to the historical data synchronization information. The selection weight values are used for measuring efficiency of the adjacent nodes synchronizing data to the target node to select, according to the selection weight values of the adjacent nodes, a target adjacent node for synchronizing data to the target node. Target data is synchronized from the selected target adjacent node with the target node.
