Embodiment Construction

[0048] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0049] figure 1 It is a schematic structural diagram of a data storage system provided by an embodiment of the present application, and the data storage system is used for storing data. In this embodiment, the data storage system includes multiple storage nodes, and for any storage node 101 among the multiple storage nodes, the current storage node 101 has at least one adjacent storage node 102 .

[0050]Multiple storage nodes refer to nodes used for data storage in the data storage system, such as multiple storage servers or multiple storage media. A plurality of storage nodes including at least one current storage node 101 has adjacent storage nodes 102 . Wherein, the adjacent storage no...

Abstract

The invention relates to a data synchronization method and device and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: receiving a data synchronization message sent by an adjacent storage node, wherein the data synchronization message is used for indicating to synchronize target data; acquiring a data synchronization path of the data synchronization message, wherein the data synchronization path is used for indicating the storage node which processes the target data according to the data synchronization message; determining whether toprocess the target data according to the data synchronization path; when it is determined that the target data is processed, processing the target data according to the data synchronization message.The problem that data consistency cannot be guaranteed in data synchronization can be solved; according to the data synchronization path, the storage node which does not process the target data according to the data synchronization message can be determined, so that the storage node processes the target data according to the data synchronization message, and the data consistency between differentstorage nodes is ensured.

Description

technical field [0001] The present application relates to a data synchronization method, device and storage medium, belonging to the technical field of computers. Background technique [0002] In a distributed system, multiple storage nodes are usually used to store data. At this time, maintaining data consistency is a crucial issue. Data consistency can be understood as the value of the same data in multiple storage nodes in a distributed system is consistent. At present, data synchronization technology is usually used to achieve data consistency of each storage node in a distributed system. [0003] Existing data synchronization technologies include a two-way data synchronization mode, that is, two-way data synchronization between two nodes can be performed. For example, the storage node S1 and the storage node S2 are adjacent storage nodes, then the data in the storage node S1 can be synchronized to the storage node S2, and the data in the storage node S2 can also be sy...
