Problems solved by technology

Among them, with the development of business and the increase or decrease of the amount of data in the distributed storage system, there will inevitably be expansion and shrinkage requirements. In addition, the data nodes in the distributed storage system may also need to realize the load due to excessive load. Therefore, data migration is required. However, the existing data migration methods are too complicated and require too much manual intervention. Moreover, if the amount of data to be migrated is too large, the migration time may be very long, and it is necessary to keep Manual intervention consumes manpower and increases the cost of data migration

Abstract

The invention discloses a data migration method, device, computing equipment and computer storage medium between nodes. Wherein, the method includes: receiving a data migration request sent by the management terminal and carrying data migration information and a version number of the first metadata information, wherein the data migration information includes: table identifier, data fragmentation identifier, source node IP port information, destination node IP port information; compare the first meta information version number with the second meta information version number recorded by the central node; if the first meta information version number is consistent with the second meta information version number, then store the data migration information in In the disk of the central node; obtain a preset amount of data migration information from the disk of the central node for processing, so as to realize the data migration between the source node and the destination node, reduce manual intervention, and avoid the problem caused by excessive data migration. The cost of data migration is too high due to large and labor-intensive operations. In addition, the data migration operation is simple and easy to implement.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data migration method, device, computing device and computer storage medium between nodes. Background technique [0002] With the continuous development of information technology, distributed storage systems appear. Distributed storage systems are highly cohesive and transparent, and meet the needs of large-scale data storage. Therefore, they have been widely used. Among them, with the development of business and the increase or decrease of the amount of data in the distributed storage system, there will inevitably be expansion and shrinkage requirements. In addition, the data nodes in the distributed storage system may also need to realize the load due to excessive load. Therefore, data migration is required. However, the existing data migration methods are too complicated and require too much manual intervention. Moreover, if the amount of data to be migrated ...
