PhotonLibOS
A high-performance C++ coroutine library for I/O-intensive applications, featuring user-space threading and support for epoll, io_uring, and DPDK.
What is PhotonLibOS?
PhotonLibOS is a C++ library designed to augment the operating system for high-performance concurrent I/O programming. It features a highly efficient user-space threading model implemented as coroutines, driven by asynchronous event engines like epoll, io_uring, and kqueue. The library solves the problem of developing I/O-intensive applications by providing fast context switching and comprehensive abstractions for networking and file I/O.
C++ developers building high-performance I/O-intensive applications, such as distributed systems, storage services, networking tools, and AI/ML infrastructure components. It is also suitable for teams in production environments at companies like Alibaba, ByteDance, and Xiaomi.
Developers choose PhotonLibOS for its exceptional performance, with coroutine switches in nanoseconds and low overhead, backed by production use in major tech companies. Its unique selling point is the combination of user-space threading, multi-platform support, and ground-up implementations of key distributed system components like RPC and HTTP, offering higher efficiency than existing solutions.
