Abstract

The invention provides a distributed database upgrade method, an upgrade processing device and an upgrade control device, and belongs to the field of distributed databases. The distributed database upgrade method comprises that: the upgrade processing device receives and stores a first database script sent by the upgrade control device; the upgrade processing device creates a new data object according to the first database script, and updates the database of database equipment; and after the upgrade is successful, the upgrade processing device switches the database script from the second database script to the first database script, wherein the second database script is a database script for processing data access requests by the upgrade processing device before upgrading and during upgrading. Each embodiment of the invention can avoid service interruption in the distributed database upgrade process. The technical scheme of the invention can be widely applied in a distributed databasesystem.

Description

technical field [0001] The invention relates to the field of distributed databases, in particular to a distributed database upgrading method, an upgrading processing device and an upgrading control device. Background technique [0002] With the development of information technology (Information Technology, referred to as IT) hardware and software and the continuous acceleration of social informatization, distributed databases are more and more widely used in communication, financial and other industries. Distributed databases can realize large-capacity, multi-category data storage, and can provide high-performance data access services externally through the collaborative work of multiple database devices, and can also be realized through database devices distributed on multiple sites. Data disaster recovery at the site level greatly guarantees data reliability and security. [0003] The introduction of a distributed database also brings great complexity and risks to the upg...
