[GitHub] [dubbo] karlchan-cn opened a new issue, #10887: 动态超时控制

[GitBox]

karlchan-cn opened a new issue, #10887:
URL: https://github.com/apache/dubbo/issues/10887

   Proposal说明-
   从consumer端,动态控制请求provider的超时时间。
   再DubboInvoker当中,calculateTimeout通过RpcContext获取time参数控制超时.
   
   问题-
   1. 由于time参数再2.7.8等2.x版本会隐式传参导致污染下游provider的参数。
   2. 希望通过增加动态参数用完即焚的方式,避免参数污染下游。
   
   解决方案request
   1. 通过增加【动态超时参数】【dynamic-timeout】,优先级比timeout参数高,有限读取动态超时参数
   2. 【动态超时参数】读取完毕,就进行参数删除
   
   实现如截图
