Abstract

The embodiment of the invention discloses a data processing method, device and system applied to a database cluster. A specific embodiment of the method comprises the following steps: receiving a dataprocessing request, wherein the data processing request comprises to-be-processed data; determining a target database sub-cluster corresponding to the data processing request according to a routing scheme generated by a preset routing rule, and determining whether the target database sub-cluster has a fault or not; and determining a target disaster recovery database sub-cluster corresponding to the target database sub-cluster in response to determining that the target database sub-cluster has a fault. According to the embodiment, on one hand, the time for processing the data processing request corresponding to the database subcluster when the database subcluster breaks down can be shortened, so that the requirement for processing the online data processing request in real time is met, andon the other hand, the overall stability of the database cluster can be improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of database technology, and in particular to a data processing method, device and system applied to database clusters. Background technique [0002] Nowadays, with the rise of the Internet of Things and mobile applications, the amount of data will increase geometrically compared to the past, and the storage of data has also been upgraded from a single database to a database cluster. Database cluster refers to the use of at least two or more database servers to form a virtual single database logical image, which provides transparent data services to clients like a single database system. [0003] Usually a database cluster consists of a master node and multiple slave nodes. The master node and slave node of the database cluster can be located in the same computer room or in different computer rooms. [0004] During the actual operation of t...
