limiter-spring-boot-starter

limiter SpringBoot Edition

中文

Support function：

• Limit Traffic
• Limited Service

Tips:

Before Current Limiting, Please Press And Measure The QPS For Accurate Current Limiting
Accurate Flow Restriction Ensures That The Service Will Not Be Shut Down Or Restarted Due To Excessive QPS, And The Service Cluster Is More Robust
The Current Limiting Operation Should Be Divided Into Transactional Operation And Non Transactional Operation, And The QPS Gap Between Them Is Usually Large
Limit Service, For Service That May Cause Delay Or High Error Rate, To Ensure The Security Of Services
