Hydro is a Rust framework for building correct and performant distributed systems using location-oriented programming, where a single program can express logic spanning multiple machines. It compiles through the DFIR (Dataflow Intermediate Representation) runtime and integrates with Hydro Deploy for launching programs locally or in the cloud.

Use cases

• build scalable distributed services in Rust that are correct by construction
• implement distributed protocols like Paxos or two-phase commit
• test distributed systems with a deterministic simulator
• deploy multi-node distributed applications to the cloud
• write low-latency stream processing dataflow programs
• reason about network reordering, duplication, and partial failure at compile time

When to choose

• you are building distributed systems in Rust and want distribution handled as a first-class concern
• you need correctness guarantees for network behavior like reordering and partial failure
• you want low-latency, high-throughput dataflow execution
• you want to test and deploy a distributed system as a single program

When to avoid

• you need a mature production framework with extensive ecosystem support
• your team is not comfortable with Rust
• you are building a simple single-machine application
• you need extensive documentation and community support right now
