Datalevin is an open-source Datalog-based database written in Clojure that runs natively on top of LMDB. It supports full ACID transactions, schema-less EDN data storage, vector search with SIMD acceleration, and text-based querying. Usable as an embedded library or as a client/server database with RBAC access, it acts like SQLite or Datomic on a ledger of immutable datoms, plus modern features like vector and full-text search.
Features
- Datalog query language with schema-less EDN storage
- ACID transactions via LMDB backend
- SIMD‑accelerated vector search support
- Full-text inverted indexing built-in
- Usable both embedded or as client/server with RBAC
- Babashka pod for scripting or REPL use
