I wonder what benefit it would bring to Dubbo? Generally speaking, it provides higher-performance, I/O uring is an async I/O mechanism, unlike select/poll/epoll_wait, it reduces the number of system calls. `cq` in I/O uring is user mode memory, so reading to `cq` will not cause the current thread to trapped into kernel mode. -- This is an automated message from the Apache Git Service.
