Fundamentals
Description A backend-neutral property graph API for Rust that models graphs as labeled nodes and edges with typed properties, expressing traversals as an intermediate representation rather than a query-language string. Ships an async GraphStore trait with adapters for SurrealDB, HelixDB, FalkorDB, LanceDB, PostgreSQL, Turso, and Spark, plus a deterministic in-memory store.A fully managed graph database service from AWS supporting both property graph and RDF models. Available as Neptune Database (for transactional workloads) and Neptune Analytics (for analytical queries).
