Show HN: S2-lite, an open source Stream Store
Summary
S2-lite is an open-source, self-hostable server implementing the S2 API, using SlateDB for storage and supporting object stores like AWS S3. It provides in-memory mode for tests and Docker-based quickstart, with architecture that streams data via per-streamer Tokio tasks and a pipelined write path to object storage. The project outlines caveats around deletion, pipelining safety, and compatibility across SDKs, signaling a practical option for real-time data ingestion and processing in lightweight deployments.
