SQL, Key-Value, Graph and Vector in One Native Database

HyperCrux is a native hybrid database. Four databases cross at one record, in one SQLite file: query it with SQL, fetch it by key, walk its graph of links, search it by vector. Same data, same transaction, so the four can't disagree. Embed it in Go, or run one small binary from any language.
