CozoDB is a multi-model database that combines relational, graph, and vector storage capabilities in a single system. It uses Datalog as its query language, enabling complex recursive queries and pattern matching across data. The database provides SDKs for many programming languages including Python, JavaScript, Rust, Go, and others, and can run embedded or as a server. Its vector support and tagline positioning it as AI memory infrastructure indicate its primary use case in RAG pipelines and LLM application backends.
