Embodiment Construction

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0079] Due to physical collisions, hardware power failures, etc., the copy of the data stored in the distributed object storage system will be damaged. Therefore, it is not only necessary to check the consistency of the data when writing the data, but also to check the Check the consistency of the data. For this, see figure 1 , the embodiment of the present invention provides a method for detecting data consistency, including:

[0080] S101. Obtain all copie...

Abstract

The embodiment of the invention provides a data consistency detecting method and device, an electronic device and a storage medium and is applied to the technical field of object storage. The data consistency detecting method comprises the steps that all duplicates of data to be detected are obtained, wherein the duplicates include data main bodies and first checkout codes, the first checkout codes are verification codes stored when the duplicates are written into a distributed object storage system; according to the data main bodies of the duplicates respectively, second verification codes ofthe duplicates are calculated through a reset algorithm; whether all verification codes are same as all second verification codes is judged; when the all verification codes are same as all second verification codes, it is determined that all the duplicates of the data to be detected have consistency. By adopting the data consistency detecting method, the data consistency of the data written intothe distributed object storage system can be detected.

Description

technical field [0001] The invention relates to the technical field of object storage, in particular to a method, a device, an electronic device and a storage medium for detecting data consistency. Background technique [0002] With the development of computer technology, the amount of data in the network has shown a blowout growth. Traditional file storage systems occupy too much space due to useless metadata, and file reading involves disk IO (Input / Output, input / output port) bottlenecks and other reasons. , has been unable to meet the storage of huge amounts of data. Object storage can store any object in a highly available system. Users and applications can use a simple API (Application Programming Interface) to access data in the object storage system. The object storage system has nearly unlimited scalability. Suitable for large amounts of data storage. Commonly used object storage systems include Google File System, Haystack, Taobao FileSystem, etc. [0003] Distri...
