摘要： A method, node and system for controlling version in a distributed system. Wherein, the method includes: a management node is selected from each domain of the distributed system; one is selected as the synchronization source of the distributed system from all the management nodes, and all the management nodes synchronize the time with that of the synchronization source; all the management nodes control the time synchronization of the nodes in their own domain according to the synchronized time; the nodes of the distributed system control the version of the duplicate copy of the storage data according to the synchronized time. According to the technical scheme, it can be realized that the rough time synchronization of the distributed system, the expansibility and the practicability are improved, and the defects of the distributed system in the prior art, such as the poor expansibility and practicability, are solved.

摘要翻译： 用于控制分布式系统中版本的方法，节点和系统。 其中，该方法包括：从分布式系统的每个域中选择管理节点; 从所有管理节点选择一个作为分布式系统的同步源，并且所有管理节点将时间与同步源的时间同步; 所有管理节点根据同步时间控制自身域中节点的时间同步; 分布式系统的节点根据同步时间控制存储数据的副本的版本。 根据技术方案，可以看出，分布式系统的粗略时间同步性，可扩展性和实用性得到提高，解决了现有技术中分布式系统的缺陷，如扩展性差和实用性差 。
