[I] brpcServer 异步处理 (brpc)
yming000 opened a new issue, #2446:
URL: https://github.com/apache/brpc/issues/2446
用echo.proto中的Echo举例，我的需求是，在Echo()运行完后，server能够直接运行一个业务函数，求各位大佬多多指教

Hi，如果是这样，你应该拓展done的生命周期，类似这样：
```
void ChatServiceImpl::Syn(google::protobuf::RpcController *cntl_base,
const HttpRequest *, HttpResponse *,
google::protobuf::Closure *done) {
auto job = std::make_shared<inference::inference_job_t>();
...
job->cntl = cntl;
job->done = done_guard.release();
infer_job_scheduler_->noNewJob(job);
...
}
```

运行done->Run()后request和response都会被析构，如果在单独业务线程中会访问req和resp会有问题

那么是在Echo 处理函数中回复了Echo response，同时启动一个线程来运行你的业务函数就行了吧

想了解brpc有没有预留这样的借口，自己起线程，感觉在程序退出时，可能会有资源访问core问题
