Abstract

The embodiment of the invention discloses a data synchronization method and device, a storage medium and computer equipment. The embodiment of the invention is related to file storage and database synchronization of cloud storage, and the method comprises the steps: obtaining a first hash tree of a data set on a first server, and obtaining a second hash tree of a to-be-synchronized target data seton a second server; starting traversal comparison based on the root nodes of the first hash tree and the second hash tree, and determining target identifiers corresponding to different target leaf nodes; determining first data and second data, corresponding to the data set and the target data set, of the target identifier; and performing data synchronization according to the difference between the version information of the first data and the version information of the second data. The data synchronization efficiency can be effectively improved.

Description

technical field [0001] The present application relates to the field of data storage, in particular to a data synchronization method, device, storage medium and computer equipment. Background technique [0002] In the process of distributed data storage, multiple copies can be set up for a piece of data in the data set, and different copies can be stored in different servers to ensure data reliability and availability. Writing is uninterrupted, but some servers are not always available, so the copy value of the data in some servers is not the latest data value for this data. [0003] During the research and practice of the prior art, the inventor of the present application found that in the process of synchronizing copies in multiple servers, a large amount of data will be read for comparison. Due to the huge amount of data in the data set, The synchronization time is often very slow, making data synchronization less efficient. Contents of the invention [0004] Embodimen...
