Building blocks Quote by Anonymous
““As with threads and locks, actors provide no direct support for parallelism. Parallel solutions need to be built from concurrent building blocks, raising the specter of non-determinism. And because actors do not share state, and can only communicate through message passing, they are not a suitable choice if you need fine-grained parallelism.””
About This Quote
Actors enable concurrency but lack built‑in parallelism, requiring explicit composition of concurrent components and risking non‑deterministic behavior.
In simple terms: Actors are good for concurrency, not fine‑grained parallelism.
Key Takeaway
Choose actors for high‑level concurrency, not low‑level parallel tasks.
