Abstract

The invention relates to a fault detection method and device for a distributed database system and electronic equipment. The method comprises the following steps: periodically determining at least two target proxy access programs from a proxy access program set; in the current detection period, triggering each target agent access program to detect the database node to obtain at least two first detection results in the current detection period; when at least two first detection results meet a preset failure condition, determining that a target detection result for the database node in the current detection period is failure; when the continuously detected target detection results of the first preset number of cycles are all failed, determining that the database node is abnormal; and judging that the database node has a fault when the database node continuously has exceptions for a preset number of times. By implementing the method and the device, the problems of low fault detection efficiency and low detection accuracy in a distributed database system can be solved.

Description

technical field [0001] The application relates to the field of data processing, in particular to a fault detection method, device and electronic equipment of a distributed database system. Background technique [0002] Traditional network storage systems use centralized storage servers to store all data, but the storage space of centralized storage servers is limited, which cannot meet the needs of large-scale storage applications. The distributed database system adopts a scalable system structure, dispersely stores data on multiple independent devices, and utilizes multiple storage servers to dispersely store data, thus providing a solution for large-scale data storage. However, in a distributed storage system, when the database storage process fails, if the failure cannot be detected in time and the running data is migrated to other devices, the service will stop and the service availability will be poor. [0003] Based on the above content, it can be known that discoveri...
