Description	A multi-model database written in Rust that runs document, key-value, columnar, timeseries, spatial, vector, and array engines in a single binary over shared storage, with graph and full-text search as cross-engine overlays on any collection. Its graph overlay uses a CSR adjacency index with 13 built-in algorithms and a Cypher-subset MATCH syntax, and fuses graph traversal with vector search in a single query for GraphRAG. Speaks SQL over a native MessagePack protocol and the PostgreSQL wire protocol, alongside HTTP/REST, WebSocket, RESP, and ILP.	A SPARQL engine capable of querying very large knowledge graphs (including complete Wikidata) on a single machine. Implements full SPARQL 1.1 with autocompletion and text search.
