mnestic

mnestic is an independently maintained fork of CozoDB — a transactional, relational-graph-vector database that uses Datalog for queries ("the hippocampus for AI"). The fork continues the project as a substrate for agentic memory, with performance, correctness, and operational work on top of upstream 481af05 (the last upstream commit, 2024-12-04).

mnestic is not the official CozoDB and is not affiliated with or endorsed by its original authors. All credit for the original design belongs to Ziyang Hu and the Cozo Project Authors. See FORK.md for provenance and licensing, and CHANGELOG-FORK.md for what diverges from upstream.

Importable name

The published crate is mnestic, but the importable Rust crate name is cozo, so existing CozoDB code works unchanged:

[dependencies]
mnestic = "0.7.6"
use cozo::{DbInstance, ScriptMutability};

The query language (CozoScript / Datalog) and engine semantics are unchanged unless noted in the fork changelog.

Features

Default is compact (SQLite backend). RocksDB, vector (HNSW), full-text search, and graph-algorithm features match upstream Cozo 0.7.x. See the crate docs and the upstream CozoDB documentation for the query language and feature flags.
