Abstract

The invention relates to the field of computer science, in particular to a data migration method and device and electronic device.The method comprises the steps that a node query message is obtained, the node query message comprises a current user identifier, and the node query message is sent when a current center node connected with a current user is not matched with the current user; and determining a historical center node corresponding to the current user based on the current user identifier, determining a connection cost of the current user and the historical center node, and when the connection cost does not meet a preset condition, triggering the historical center node to migrate data of the current user to the current center node. According to the method and the device, the data in the historical nodes are migrated into the existing nodes when the original nodes are determined to be unavailable by checking the historical nodes and tentative linking the original nodes, so that the timeliness of the data is ensured while the accuracy of the data is ensured, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of computer science, in particular to a data migration method and device, and electronic equipment. Background technique [0002] In order to ensure the availability and robustness of the software, and to be compatible with the possible network conditions of users in different regions, our services usually build multi-center nodes in different places. [0003] These nodes are not the same as edge nodes. Edge nodes usually cache static data, or return customers after simple processing of static data. Generally speaking, edge nodes do not record business data generated by user activities. But the central node is different. The central node needs to be sensitive to the business data generated by the customer at all times and has real-time performance. When a customer operation generates new business data changes, the database must be updated immediately. If the customer's next operation is different from this time Opera...
