Orisun
Orisun is an open-source event database built for Command Context Consistency (CCC).
Applications declare the event context behind a decision with content-based queries. Orisun commits new events only if that context is still current, preserving the complete event history without forcing consistency rules into fixed streams or aggregates.
Orisun provides:
- Transactional event storage with SQLite, PostgreSQL, YugabyteDB, and FoundationDB (beta).
- Query-driven optimistic concurrency with content-scoped consistency checks.
- Per-boundary ordered catch-up and live subscriptions through embedded NATS JetStream.
- Event-backed boundary creation and import at runtime, without a startup boundary list.
- gRPC APIs, generated clients, server binaries, Docker images, and embedded runtimes.
Documentation
See the Orisun documentation for concepts, setup, the Admin boundary API, client libraries, embedding, migration, and operations. Existing deployments should follow the dedicated 0.7.0 to 0.8.0 upgrade guide before changing their server version.
