Maelstrom is a distributed-systems workbench by the Jepsen team. It provides standardized JSON-based protocols and test harnesses (via Jepsen) to validate the behavior of custom toy systems—like commutative sets or transactional key-value stores—under simulated failure conditions. You implement your server in any language, connect through stdin/stdout, and the framework injects network disruptions, partitions, and consistency checks.
Features
- JSON protocol-based node interface over stdin/stdout
- Built-in tests for common distributed patterns
- Simulated network partitions and failures
- Language-agnostic node implementation
- Ideal for teaching/testing consensus algorithms
- Actively used in distributed-systems workshops
