C++ Coroutines at Scale - Implementation Choices at Google - Aaron Jacobs - C++Now 2024
---

Google is now using C++ coroutines to process billions of requests per second. This talk presents trade-offs and novel choices made in developing our coroutines library, and integrating it into the Google production environment. The talk covers both performance and semantic questions that affect usability and software engineering at scale.

Topics include:

The importance of mandatory support for cancellation.
Library and compiler support making it feasible to safely accept reference parameters in coroutines.
The benefits and limitations of structured concurrency APIs.
Unifying deadlines and cancellation.
Stack-efficient async programming, including techniques for stack-efficient cancellation, and where the language is still missing features.
Trade-offs between API usability and bounded parallelism executors.
Propagation of "context" information like tracing and security credentials.
Using coroutines to improve the usability of APIs for making and receiving streaming RPCs.
