Abstract

The invention discloses a data online migration method and device, and relates to the technical field of computers. The method comprises the following steps: regularly inquiring a migration switch identifier and a dual-operation switch identifier of a cache center; when the migration switch identifier is in an on state and the dual-operation switch identifier is in an on state, obtaining to-be-migrated data from a source database, and storing the to-be-migrated data into a task pool; and migrating the data in the task pool to a target database based on a multi-thread or distributed task execution mechanism. Through the steps, data migration can be executed on the premise that a user is unperceived and the use of a service system is not influenced, so that the data migration speed and the migration accuracy are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data online migration method and device. Background technique [0002] At present, due to the increasing number of merchants and various inquiries from merchants, the processing speed of the inquiry form by the database is getting slower and slower, which greatly affects the work efficiency. In addition, due to the high real-time requirements for receiving consultation data, the pressure on the database is also increasing. In view of this, there is a need to migrate system data. [0003] In the prior art, data migration is mostly performed in an offline manner. This migration method has at least the following problems: the migration process needs to stop online projects or only support data query operations, resulting in unfriendly user experience; in the existing technology, data migration tasks are executed regularly, which has the disadvantage of being uncontroll...
