Queue flow limiting method and storage medium

Abstract

The invention provides a queue flow limiting method and a storage medium, and the method comprises the steps: formulating a classification flow limiting strategy according to a preset CPU resource occupation threshold and a preset memory resource occupation threshold, and the classification flow limiting strategy comprises a calculation type strategy and a memory type strategy; if the request is configured to be the classified flow limiting strategy, when the client receives the request of writing the application into the message queue, judging whether the request corresponds to a computing type application or a memory type application; if the application is the computational application, executing a computational strategy; and if the application is the memory type application, executing the memory type strategy. According to the invention, good system performance can be ensured; current limiting judgment can be carried out in a more targeted manner, and the practicability is high; more importantly, a monitoring server and an intercepting server do not need to be additionally deployed, the queue program is directly utilized for implementation, and resources and time are greatly saved.

Description

technical field [0001] The invention relates to the field of system request processing, in particular to a queue current limiting method and a storage medium. Background technique [0002] The purpose of current limiting is to protect the system by limiting the rate of concurrent access / requests or requests within a time window. Once the limit rate is reached, the service can be denied (directed to an error page or notified that the resource is gone), queued or Waiting (such as seckill, commenting, placing an order), downgrading (returning pocket data or default data, such as inventory on the product details page is in stock by default). [0003] There are limited stream functions in many systems today. However, under normal circumstances, current limiting is only performed on interfaces. For example, perform pressure tests on certain interfaces to know the approximate throughput, and then limit the flow of interface requests. The above is a general practice, and many sys...

Problems solved by technology

For example, the current limit for queues in some software is generally limited according to the length of the queue. For example, if the number of queues reaches 10,000, it will be limited. However, if the number of queues reaches 10,000, the CPU has reached 90% or the memory usage rate Reached 90%, since the condition of the restriction has not been met, the purpose of the restriction has not been achieved

But at this time, the resources are already full, and the system performance is seriously affected, which may lead to the inability to perform normal functions.
