Stoolap is an embedded SQL database written in pure Rust. It combines transactional workloads (OLTP), analytical queries (OLAP), and native vector search in a single serverless runtime.
Historical note: Stoolap started as an early Go prototype. The project is now fully migrated to Rust, and all active development and releases happen in the Rust codebase.
- Embedded first architecture with no external database server
- Modern SQL engine with MVCC and cost based optimization
- Native vector and semantic search with HNSW
- Predictable performance for real time applications
