| Description | An object-store-native distributed graph database written in Rust, built on SlateDB with S3-compatible storage as the durable source of truth. Queries a subset of openCypher over Bolt, so Neo4j drivers connect unmodified, or over an HTTPS API, with query nodes and indexers scaling independently of storage. | A multi-model database written in Rust that combines document, graph, and relational paradigms. Uses inter-document record links for graph traversals, with ACID transactions and row-level permissions. |
