Implementations of the present specification disclose a graph structure data processing method and a storage engine and device for graph structure data. The method can be implemented by using the storage engine for graph structure data, and includes: receiving a storage request for first data of a target graph, the storage request including a graph identifier of the target graph and the first data; obtaining historical data of the target graph corresponding to the graph identifier from a storage component based on the graph identifier, determining target data that corresponds to a change of the first data of the target graph relative to the historical data, and generating version information corresponding to the target data, the target data including data of a node in the first data of the target graph and/or data of an edge in the first data of the target graph; and mapping a node and/or an edge associated with the target data in the target graph, and storing the target data in the storage component with reference to the version information.
