Abstract

The invention relates to the field of distributed storage, in particular to a data synchronization method and device in distributed object storage, equipment and a medium. The method comprises the following steps: writing changed bucket fragments into a first-level log through synchronization operation in a completion stage of executing an uploading process at a master site, and synchronizing the changed bucket fragments to all slave sites; writing changed objects on the bucket fragments into a second-level log through asynchronous operation in the finishing stage of executing the uploading process at the main site; the main site detects the disk falling state of the second-level logs and records bucket fragment information corresponding to the second-level logs which successfully fall into the disk; the master station sends the bucket fragment information to all slave stations; and the slave site with the competitive lock requests the master site to obtain the second-level log based on the bucket fragment information, and updates the changed object of the slave site based on the first-level log and the second-level log. According to the invention, the problem of data synchronization omission caused by combination of an uploading mechanism and a synchronization mechanism is solved, the function of data synchronization is optimized, and the robustness and accuracy of data synchronization are improved.

Description

technical field [0001] The present invention relates to the field of distributed storage, and in particular, to a method, device, device and medium for data synchronization in distributed object storage. Background technique [0002] Distributed storage is to store data scattered on multiple independent devices. It adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses location servers to locate and store information. It not only improves the reliability, availability, and storage of the system. Access efficiency, but also easy to expand. In the current distributed object storage system, when multiple sites are configured, if any one of the sites has data changes, all other sites will monitor the change and perform the same operations to ensure that the data in all data centers are exactly the same. To achieve the effect of remote disaster recovery. [0003] At present, traditional distributed storage adopts upload mechanism c...
