README.md

Hydro is a high-level distributed programming framework for Rust. Hydro can help you quickly write scalable distributed services that are correct by construction. Much like Rust helps with memory safety, Hydro helps with [**distributed safety**](https://hydro.run/docs/hydro/reference/correctness).

Hydro integrates naturally with standard Rust constructs and IDEs, providing types and programming constructs for ensuring distributed safety. Under the covers, Hydro is powered by the Dataflow Intermediate Representation (DFIR), a compiler and low-level runtime for stream processing. DFIR enables automatic vectorization and efficient scheduling without restricting your application logic.

# Learn More
- **Docs**: There are docs for the [high-level Hydro framework](https://hydro.run/docs/hydro/reference/) and the low-level dataflow IR, [DFIR](https://hydro.run/docs/dfir), as well as the [Hydro Deploy](https://hydro.run/docs/hydro/reference/deploy/) framework for launching Hydro programs.

- **Research Papers**: Our [research publications](https://hydro.run/research) are available on the project website. Some notable selections:
    - The original Hydro vision paper from CIDR 2021: [New Directions in Cloud Programming](https://hydro.run/papers/new-directions.pdf)
    - The first paper on optimizations from SIGMOD 2024: [Optimizing Distributed Protocols with Query Rewrites](https://hydro.run/papers/david-sigmod-2024.pdf)
    - The first paper on Hydro's formal semantics to appear in POPL 2025: [Flo: a Semantic Foundation for Progressive Stream Processing](https://arxiv.org/abs/2411.08274)
