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 and Dynamic Consistency Boundary-style append conditions.
- Per-boundary ordered catch-up and live subscriptions through embedded NATS JetStream.
- gRPC APIs, generated clients, server binaries, Docker images, and embedded runtimes.
Documentation
See the Orisun documentation for concepts, setup, APIs, client libraries, embedding, and operations.
