The embodiment of the application discloses a data synchronization method in a distributive system, and a distributive system. The distributive system comprises at least two subsystems, wherein the subsystems are positioned on different data centers, each subsystem consists of a consumer module, a producer module, a consumer storage module, and a producer storage module; in the subsystem positioned on any one data center, the producer module produces data, writes the produced data into the consumer storage module and the producer storage module of a local subsystem; the consumer module reads data from the consumer storage module of the local subsystem, and processes the read data; the producer storage module stores the data written by the producer module of the local subsystem, and synchronizes the stored data to the consumer storage module in the subsystems in other data centers except for the data center at which the local subsystem is positioned; and the consumer storage module stores the data written by the producer module of the local subsystem, and the data synchronized by the producer storage module of the subsystems positioned in other data centers except for the data center at which the local subsystem is positioned. According to the embodiment of the application, the data synchronization method and the distributive system can be used for supporting local consumers to process the data produced by remote producers. |
