Embodiment Construction
[0041] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
[0042] It should be noted that the embodiments of the present invention are applicable to a distributed architecture, and may also be applicable to situations where there are software-level dependencies between other systems or service components. For the convenience of unified description, for the dependent services, for example, the called system and the called component...

The invention discloses a disaster recovery and degradation method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of receiving a calling request for a dependency service, and obtaining the identification information of a thread pool corresponding to the dependency service so as to determine the thread pool; obtaining the callinginformation of the threads in the thread pool in the current preset time period, and when the calling information meets the preset degradation condition, executing the disaster recovery degradation on the dependency service based on the preset degradation mode. The implementation mode depends on a thread pool isolation mechanism, so that the disaster recovery capability of the system is improved,and the situation that the whole system is unavailable and even crashes due to the fact that a single dependent service is unavailable is avoided. In addition, on the basis of the disaster recovery mechanism of automatic degradation and elastic recovery of the dependent service, the automatic processing of the system is guaranteed, the rapid response capability of the system is improved, and meanwhile the human intervention is reduced.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for disaster recovery and downgrade. Background technique [0002] With the rapid development of the Internet, more and more systems adopt distributed architecture. In the distributed architecture, there are two kinds of dependencies: the system's dependence on some common components (such as mysql, ES, Redis, MQ, etc.), and the dependence between systems. The stability of these dependencies has a greater impact on the operation of the system . When a component or service is unavailable, such as a slow network connection or a busy resource, it may cause the system to be unavailable. Therefore, how to avoid the impact on the system caused by the unavailability of dependent components or services, especially in high concurrency scenarios, and improve the disaster recovery capability of the system is particularly important. [0003] In the prior art, the ado...
