Coroutines and gRPC

13:00 - 14:00 Saturday 2nd March 2024 UTC

Coroutines have a lot of potential, but a lack of library support means that they're difficult to get started with. In this talk, we look at how coroutines can be used to write high-performance gRPC procedures that can easily be composed with other coroutine libraries.

The talk starts with a quick recap of coroutines, moves on to a brief overview of gRPC, and ends with a close look at how to write the support code that allows us to use coroutines with the gRPC callback interface.

There is a clear focus on how coroutines can be used in production, today, and what we as developers need to write in order to enable their usage. After this talk, you should feel confident getting started writing coroutine support code for your own use-case.

We currently have an internal support library that we're hoping to publish as open source on GitHub (with documentation and demos)
