io_uring: Two rings makes computers go Brrrrr (S04E05)

from The Technium Hosted by The Technium

io_uring is a new asynchronous, API to enable fast and efficient system calls in the Linux kernel. It promises faster user-land programs that heavily use file system IO on Linux, for all applications, not just databases. 00:00 S04 E05 io_uring 02:55 What is io_uring? 05:59 What's wrong with existing async interfaces? 17:25 Copying is slow 19:05 Two ring buffers 28:07 What would the effect for the end user be? 34:50 Different operating modes 37:27 C10K for Filesystem IO 43:04 Speed is simplicity 47:07 Deconstructed databases 01:02:12 Effect systems 01:06:26 System functionality in programming language 01:10:55 OS as Actor Model 01:16:08 The Kernel is Userland ===== About “The Technium” ===== The Technium is a weekly podcast discussing the edge of technology and what we can build with it.
