Show HN: PardusDB – SQLite-like vector database in Rust

PardusDB is a lightweight, single-file embedded vector database written in pure Rust — think SQLite, but for vectors and similarity search.

Key highlights: - No external dependencies - Familiar SQL syntax for CREATE/INSERT/SELECT + vector SIMILARITY queries - Graph-based ANN search, thread-safe, transactions - Python RAG example with Ollama included

We built this as the engine behind our no-code platform at https://pardusai.org/ (private, local-first data analysis).
