[GitHub] [dubbo] mrhbj opened a new issue #9270: dubbo MigrationInvoker promotion problem

[GitBox <gi...@apache.org>]

mrhbj opened a new issue #9270:
URL: https://github.com/apache/dubbo/issues/9270


      MigrationInvoker promotion is default 100, so this judge has problem,because it is inefficient, it doesn't need to use ThreadLocalRandom.current().nextDouble(100) where promotion is default 100.
    
      @Override
       public Result invoke(Invocation invocation) throws RpcException {
           if (currentAvailableInvoker != null) {
               if (step == APPLICATION_FIRST) {
                   // call ratio calculation based on random value
                   if (ThreadLocalRandom.current().nextDouble(100) > promotion) {
                       return invoker.invoke(invocation);
                   }
               }
               return currentAvailableInvoker.invoke(invocation);
           }
