io_uring is a fairly new I/O interface in the Linux kernel. It represents a shift in how applications interact with the kernel. Instead of transferring control through a system-call interface into kernel mode, operations are submitted asynchronously through shared queues. This talk discusses patterns for dealing with asynchronous I/O and demonstrates a setup for high-volume file reading using this framework, illustrated with code examples in C++. Lumiera is a video editing application under development in C++ and serves here as a real-world example showing how asynchronous I/O can play a key role in achieving adequate throughput for video processing.
