Dmitry has been using C++ in his routine work for 17 years, mostly focusing on complex asynchronous I/O-bound applications. After working in companies like Yandex and Google, he joined Hudson River Trading, a quantitative trading firm in New York, where he develops and improves research infrastructure, and also keeps people entertained by bringing last additions to C++ to the code base.
C++20 coroutines present some exciting opportunities for organizing and simplifying concurrent logic, but they have proven challenging to integrate with production systems. Object lifetime and execution order issues can be difficult to manage, especially without guidance from well-established best practices. Practical use requires interoperability with existing event loops and with non-coroutine-aware components. While some experimental libraries have started to be released, the C++ “async ecosystem” is still young compared to many other languages. We will describe our path through this thicket and introduce Corral, a new open-source concurrency framework for C++ that attempts to tame it. Corral is built around […]
