A multi-dimensional service current limiting method and system based on shared memory between containers

Abstract

The embodiment of the present invention provides a multi-dimensional service current limiting method and system based on shared memory between containers, the method includes: for several application processes on the same server, map the current limiting count file to the application process by MMAP technology In the virtual address space, for any application process, according to the type of any application process, three dimensions of any application process are selected for current limiting. The embodiment of the present invention provides a multi-dimensional service current limiting method and system based on shared memory between containers, which not only solves the problem that traditional current limiting methods cannot cross service containers, but also solves the problem of general distributed current limiting algorithms accessing three-party middleware A good balance has been achieved between the performance issues brought about.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and system for multi-dimensional service current limiting based on shared memory between containers. Background technique [0002] In a high-concurrency real-time trading system, when the request traffic of a certain service suddenly surges and influxes continuously, a series of problems such as high service load and network response delay will occur, and a chain reaction may occur, triggering an avalanche, causing other A service is unavailable which, if not addressed, could render the entire system unavailable. [0003] Therefore, it is very important to control the traffic in the service. The high availability and stability of the service can be guaranteed through reasonable restrictions on the traffic. [0004] The classic current limiting algorithm proposed based on the current limiting problem solves the impact of unexpected burst t...

Problems solved by technology

[0004] The classic current limiting algorithm proposed based on the current limiting problem solves the impact of unexpected burst traffic on the system, but these algorithms can only limit the current within a single process, and now typical Internet systems are built on Based on micro-service and container technology, the traditional current limiting algorithm cannot meet the requirements of cross-process or even cross-service container current limiting
