Embodiment Construction

[0016] Embodiments of the present invention provide a data synchronization method, a node, and a storage service cluster, which can reduce the number of object synchronizations, thereby saving computing resources.

[0017] Please refer to figure 1 , an embodiment of the data synchronization method in the embodiment of the present invention includes:

[0018] 101. The slave node in the storage service cluster receives the request for acquiring the first object sent by the client;

[0019] In this embodiment, the slave node may receive the request for obtaining the first object sent by the client, where the request for obtaining the first object includes the identifier of the first object. In the prior art, the object is a set of data, and each The object has a unique identifier, and the update of the object is only the update of the value of the data, but the identifier will not change.

[0020] 102. When the slave node stores the first object and the version number of the fi...

Abstract

The embodiment of the invention discloses a data synchronous method, a node and a storage service cluster. The method comprises the steps that the node receives a request sent by a client side for obtaining a first object, when the first object and a version number of the first object are stored in the node, the version number of the first object stored in a main node is inquired according to an identifier of the first object of the node, whether the version number of the first object stored in the node is identical with the first version number, inquired from the main node, of the first object is judged from the node, and if not, the first object and the version number of the first object stored in the node are synchronously updated into the first object and the first version number in the main node. Accordingly, when the client terminal needs to read the object, the node determines update of the object by comparing the version number of the object stored in the node with the version number of the object stored in the main node, and synchronously updates the updated object, and therefore times of synchronization of the object can be reduced, and computing resources are saved.

Description

technical field [0001] The invention relates to the communication field, in particular to a data synchronization method, a node and a storage service cluster. Background technique [0002] In the existing storage service cluster, the data synchronization method of each node is broadcast synchronization. For example, when an object is updated in node 1, node 1 will notify other nodes that store the object that the object has been updated, so that other The node storing the object can be synchronized with the node data, but since it cannot be guaranteed that the object in each node will be accessed and read, the broadcast synchronization causes a waste of computing resources. The computing resources mainly include: bandwidth , processor and input and output resources. Contents of the invention [0003] The invention provides a data synchronization method, a node and a storage service cluster, which can solve the problem of waste of computing resources. [0004] The data sy...
