- Distributed systems are fundamental in modern computing but challenging to program due to non-deterministic behaviors like message reordering, retries, and failures.
- Existing programming languages lack support for reasoning about global behavior in distributed systems.
- A new foundation for distributed programming is introduced, offering richer correctness guarantees and modularity opportunities.
- Generalized asynchronous streams capture distributed semantics in types and ensure determinism by restricting downstream behavior.
- The model allows writing entire distributed protocols in a single function, encapsulating network and concurrency.
- The framework Hydro, implemented in Rust, leverages staged programming for high-level streaming and bare-metal performance.
- Optimization techniques like program synthesis and term rewriting are explored for distributed systems.
- The work demonstrates a practical, correct, and efficient programming model for building reliable and scalable distributed software.
