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
