Io uring
From dankwiki
io_uring, introduced in 2019 by Jens Axboe, is a system for providing the kernel with a schedule of system calls, and receiving the results as they're generated. It combines asynchronous I/O, system call polybatching, and flexible buffer management, and is IMHO the most substantial development in the Linux I/O model since Berkeley sockets:
- Asynchronous I/O without the large copy overheads and restrictions of POSIX AIO (no more O_DIRECT, etc.)
- System call batching across distinct system calls (not just readv() and recvmmsg())
- Whole sequences of distinct system calls can be strung together
- Provide a buffer pool, and they'll be used as needed
