Abstract

One or more embodiments of this specification disclose a data migration method and device, which are used to improve the migration success rate and migration performance of data segments. The method includes: when migrating the data segments to be migrated in the first server to the second server, determining the first quantity of the data segments to be migrated; Maximum migration amount; according to the first number and the maximum migration amount, determine a migration strategy for the data segment to be migrated; wherein, the migration strategy includes at least the number of migration times and / or a single migration amount; according to the The migration policy migrates the data segment to be migrated to the second server.

Description

technical field [0001] This specification relates to the technical field of data processing, and in particular to a data migration method and device. Background technique [0002] In a traditional cache cluster that solves data balance through the principle of hash slots, the data segments that a single server should store are often calculated based on the total number of servers and the total number of hash slots, and each server maintains a copy of its own Managed data segments. When a new server is added, the data segment that needs to be maintained by each server will be recalculated, and the data segment will be adjusted according to the calculation result. After the data segment migration is completed, the old server will maintain the data segment that needs to be migrated and the migrated data segment. The imported data segment. [0003] In the prior art, the data segments maintained by the server are usually migrated in a manner of even data distribution. For exam...
