Abstract

The invention relates to a data online migration method and device, electronic equipment and a storage medium, and belongs to the technical field of data processing. The method comprises the steps that when a first business device is controlled to provide a transaction service, to-be-migrated data is determined, and the first business device corresponds to a first database; initializing and migrating the to-be-migrated data from the first database to a second database, wherein the second database corresponds to a second business device; and after the to-be-migrated data is initialized and migrated from the first database to the second database, controlling the second business device to provide a transaction service to the outside. According to the technical scheme, online migration of the data between the databases can be achieved, the efficiency of data migration between the databases is effectively improved, in addition, due to the fact that the corresponding service devices are still controlled to provide the transaction service externally in the migration process, the influence of data migration on the transaction service can be effectively reduced, and online non-stop migration is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of big data data processing, and in particular to a data online migration method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of the Internet, the number of users of Internet mobile applications has shown an unprecedented scale. The number of users of large-scale applications has reached billions, and the amount of data has reached hundreds of billions. In the process of system operation, maintenance and upgrading, the technical team will almost always encounter problems that need to be upgraded and relocated. Data migration is a key part of data system integration to ensure smooth system upgrades and updates. [0003] In related technologies, data migration is downtime migration. In a business scenario with a huge amount of data and high-frequency access, the data migration efficiency is low, and downtime migration affects the normal op...
