Abstract

The invention discloses a data synchronization method, a data synchronization device and a distributed system. A management node obtains a routing update message indicating to update the routing information of the first data center and the second data center, wherein the The routing information includes at least identification information of the first data center and the second data center and backup routing information of nodes in the first data center and the second data center; the management node according to the route update message, adjusting the routing information of the first data center and the second data center; the management node synchronizes the adjusted routing information of the first data center and the second data center to the In the first data center and the second data center, the first data center and the second data center synchronously transmit the data of each node under their jurisdiction based on the adjusted routing information.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data synchronization method, a data synchronization device and a distributed system. Background technique [0002] With the development of big data technology, in order to effectively solve the problems of risks and access delays caused by data concentration, it is usually based on a distributed system to build a multi-data center including a service data center and a backup data center, and to confirm the above in real time The operating status of each data center in the multi-data center and the servers inside the data center. Taking the service data center as an example, when a certain service data center cannot operate normally, the follow-up user's access will be directed to another normal one based on the principle of proximity. running service data center; and when a server in a certain service data center is not operating normally, follow-up user access is also directed to a...
