Service degradation method and apparatus, and distributed task scheduling system

Abstract

The invention relates to a service degradation method and apparatus, and a distributed task scheduling system. The method comprises the following steps: when it is determined that a distributed task scheduling system needs to execute server degradation operation, according to an amount of current user access to a service function already registered on the distributed task scheduling system and a preset threshold scope set, determining that the access amount of the service function falls into a first threshold scope; and according to the first threshold scope and a first mapping relation corresponding to the service function, determining first service degradation operation currently to be executed by the distributed task scheduling system, wherein the first mapping relation comprises corresponding relations between different threshold scopes under the service function and the service degradation operation The distributed task scheduling system in the embodiments of the invention can obtain degradation schemes with different adaptability for different access amounts, emergency conditions are handled, and the service degradation flexibility of the distributed system is improved.

Description

Technical field [0001] The present disclosure relates to communication technology, and in particular, to a method and device for service degradation and a distributed task scheduling system. Background technique [0002] Business degradation refers to the sacrifice of some non-core functions in order to ensure the stability of the core functions of the distributed environment system at certain times. To achieve a good business degradation, it is necessary to split each function of the functional business to reduce the dependence between each function. The business mentioned here can include a variety of application businesses, such as querying databases and paying for goods. [0003] When degrading services in a distributed environment, it is necessary to ensure the timeliness of the degrading of each service node. However, the current business degrading plan in a distributed environment is relatively simple, and it is often the case that the user's business needs cannot be met. ...
