●●SolidWizardryBold Bet

Postgres wire protocol in Rust with vector and graph in one engine.

Strengths
  • •Wire-protocol compatibility means zero code changes for existing Postgres clients
  • •Custom storage engine with HNSW and IVF indexes built from scratch
  • •Graph queries run over the same tables as vector and relational data
Weaknesses
  • •Alpha software with BSL license limits production adoption
  • •Competing against well-funded Neon, Chroma, and pgvector combinations
Target Audience

PardusDB – SQLite-like vector database in Rust

Using a single-file .pardus format with CREATE/INSERT/SELECT + SIMILARITY queries gives a very familiar developer UX for embedding storage. The combination of graph-based ANN, full transactions, thread-safety, and zero external dependencies is an uncommon and useful engineering combo for local-first AI work; it would win more attention with benchmark comparisons and richer ecosystem integrations (connectors/clients).
