Abstract

The invention discloses a data migration method, a data migration device, a storage medium and equipment and. According to the invention, when the load balancing state of the system does not meet thepreset condition, selecting a plurality of first nodes and second nodes from the system, forming a to-be-emigrated node set and a to-be-immigrated node set; based on the load capacity of each first node, selecting a to-be-processed node from the to-be-emigrated node set, determining a target migration node based on the average migration cost, migrating the data of the to-be-processed node to a target migration node, the to-be-processed node is moved out from the to-be-migrated node set; when the first node still exists in the to-be-migrated node set. According to the invention, the migration nodes are sorted on the basis of the average migration cost, and then the target migration node is selected. Therefore, the overall migration cost of the whole system is reduced. The data migration time is shortened, and the data throughput of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of distributed cache, in particular to a data migration method, equipment, storage medium and device. Background technique [0002] The Redis cluster distributed cache system will evenly distribute data to each cache node, but when the number of cache nodes in the cluster changes, the balanced state of the data load of each cache node in the cluster will be broken. In order to make the Redis cluster reach a balanced state again, data migration operations need to occur between each cache node. However, when the current Redis cluster performs a data migration operation, the method of randomly selecting the migration object will cause a high migration cost when the cluster has many nodes participating in the data migration. In the cost-sensitive data migration algorithm, when selecting the migration object, it will first calculate the cost of migrating data from the outgoing node to the incoming node i...
