You’ve probably spent years wrestling with callbacks, mutexes, and thread pools, thinking you’ve finally conquered C++ concurrency. But what if I told you the framework you’re relying on is already a dinosaur? If you’re still maintaining bespoke async infrastructure, you’re driving a horse-drawn carriage on a hyperloop track. Welcome to The Concurrency Convergence.
The Concurrency Convergence isn’t just a buzzword; it’s a brutal reality check. When Apple open-sourced FoundationDB’s Flow, it was hailed as a masterpiece of C++11 engineering. It forced actor-based concurrency into a language that desperately wanted nothing to do with it. It was brilliant. But today? It’s a massive liability.
If your concurrency model requires a PhD to understand, it’s not a feature—it’s a trap.
Enter C++20. Native coroutines finally arrived, and suddenly, the magic trick of Flow looks like a parlor game. Why force a custom actor model into C++11 when the language itself now speaks async fluently? The technical debt is piling up fast. Every new contributor looking at Flow has to unlearn modern C++ just to understand what’s happening under the hood.
Bespoke infrastructure is a love letter to the past that taxes your future.
And Apple knows it. That’s why they are rewriting FoundationDB’s simulation layer in Swift. This isn’t just a side project; it’s a massive, flashing signal. When the creators of a bespoke C++ framework start migrating to a modern, language-native approach, you know the era of custom concurrency is ending. The Concurrency Convergence demands that we stop fighting the language and start using it.
The best framework is the one you don’t have to build.
Stop clinging to outdated paradigms out of misplaced loyalty. The Concurrency Convergence means native language features are eating custom frameworks alive. Embrace C++20 coroutines, look at Swift, and let your codebase breathe. Your future developers will thank you.
FAQ
Q: What exactly is The Concurrency Convergence?
A: It is the industry shift where native language features like C++20 coroutines are replacing custom, bespoke concurrency frameworks, making them redundant and overly complex.
Q: Why is FoundationDB's Flow considered outdated now?
A: Built for C++11, Flow relies on complex custom abstractions that now act as a barrier to entry for new developers compared to the familiarity of native async/await features in modern C++.
Q: What does Apple's Swift rewrite of FoundationDB signal?
A: Rewriting the simulation layer in Swift indicates a strategic move away from custom C++ paradigms toward modern, language-native concurrency models.
Q: Should I still build custom actor models in C++?
A: Probably not. Unless you have highly specific needs, leveraging native C++20 coroutines will save you massive technical debt and significantly reduce onboarding time for new contributors.
