'Swift as C++ Successor in FoundationDB' by Konrad Malawski (Strange Loop 2023)
Показать описание
Programming languages often prioritize either performance or ergonomics. Swift offers a unique modern type-safe low-ceremony approach taking the best of both worlds that scales from mobile apps to high-performance systems where previously memory-unsafe languages would be used. It also interoperates seamlessly with C and C++.
In this talk, we show how we successfully adopted Swift in FoundationDB, a distributed database struggling to modernize its C++ codebase. Swift's interoperability features allowed the team to incrementally move single functions, or entire types, to Swift. This transition was done without generating any bindings and while preserving the existing semantics.
FoundationDB uses a custom actor runtime, which enables reproducible simulation testing. Again, Swift's flexible concurrency and distributed actor model enabled an incremental side-by-side approach by having Swift concurrency seamlessly execute on the existing scheduling infrastructure.
