Fundamentals
Description A temporal RDF graph database written in Rust. Each transaction is an immutable, content-addressed commit, so data can be queried as of any point in history, with git-style branching, triple-level access policies, and built-in full-text, vector, and geospatial search.A distributed property graph database with separated storage and computation layers, enabling horizontal scaling. Uses a custom SQL-like query language (nGQL) and supports ACID transactions.
