Multi-dimensional dynamic grouping flow limiting method and device, equipment and storage medium

The invention relates to a flow control technology of a distributed system which can be applied to the financial field or other fields, and provides a multi-dimensional dynamic grouping flow limiting method and device, equipment and a storage medium, and the method comprises the steps: determining whether the business request quantity at the current transaction moment is abnormal or not; when the business request quantity at the current transaction moment is abnormal, acquiring the current entropy uncertainty proportion of the application; and according to the entropy uncertainty proportion and the business request amount, carrying out service-level current limiting, service group-level current limiting or application-level current limiting. The embodiment of the invention can improve the operation stability of the application system. 本说明书涉及可应用于金融领域或其他领域的分布式系统的流量控制技术，提供了一种多维动态分组限流方法、装置、设备及存储介质，该方法包括：确认当前交易时刻的业务请求量是否异常；在当前交易时刻的业务请求量异常时，获取应用当前的熵不确定性比例；根据所述熵不确定性比例及所述业务请求量进行服务级限流、服务群组级限流或应用级限流。本说明书实施例可以提高应用系统的运行稳
