v0.1.0 — Initial Release

Ripple v0.1.0

Distributed, type-safe, incremental stream processing in OCaml.

Highlights

• 250ns per stabilization at 10K symbols (12x under 3μs target)
• 2.16M events/sec sustained VWAP pipeline throughput
• 2.1s recovery from 6M event replay (14x under 30s target)
• 12.2M roundtrips/sec bin_prot serialization
• 128ns schema compatibility checking

Components

• 16 OCaml libraries covering graph engine, schema, wire protocol, transport, checkpoint, windowing, observability, coordinator, worker
• 3 binaries: ripple-vwap-demo, ripple-worker, ripple-cli
• Docker Compose integration stack (Redpanda + MinIO)
• Kubernetes manifests (StatefulSet, Deployment, ConfigMap)
• CI/CD pipeline with benchmark regression gate

Testing

• 117 inline expect tests
• 11 property-based tests (6,500+ iterations)
• 4 load tests (sustained throughput, memory stability, latency, O(1) recomputation)
• 3 chaos tests (100/100 random crash points produce correct recovery)
• Docker Compose end-to-end integration
