Abstract

The invention provides a data migration method and device, a computer readable storage medium and electronic equipment, and relates to the technical field of data management. The data migration method comprises the following steps: receiving a data migration instruction; determining a data migration direction between each existing original cache data fragment and each newly deployed target cache data fragment in the cache data cluster; according to the data migration instruction, migrating to-be-migrated data in the original cache data fragment to the target cache data fragment according to the data migration direction, and maintaining a migration state in the original cache data fragment; and sending a migration result recorded in the migration state to a migration management module. According to the method and the device, the cache system can be expanded through data migration on the premise of not stopping service, the migration process optimizes the management of the state of the data to be migrated, and the migration can be restarted from the interruption position, so that the data migration process is more convenient and efficient.

Description

technical field [0001] The present disclosure relates to the technical field of data management, and in particular, to a data migration method, a data migration device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In order to solve the disadvantages of using relational database to store data in the traditional development model, the method of using cache to store hot data came into being. The high performance of cache can provide high-throughput and low-latency data access. However, with the increase in the number of mobile Internet users, the cache of a single computer cannot meet the needs of users for storing and accessing massive data. Massive concurrent requests from users. For a distributed cache system, the most important capability is capacity expansion. The distributed cache system can deploy new storage space resources and migrate some data from the original storage space to the newly deployed storage space. accompli...
