Summary
Spencer Judge, leading Temporal's SDK team, details an architecture using a shared Rust core with language-specific layers to avoid rewriting ~70,000 lines of complex state machine logic across eight SDKs. He covers practical challenges like FFI boundaries, async bridging, and memory safety, contrasting native extensions with emerging WebAssembly approaches for cross-language portability.
