cognee-community-hybrid-adapter-helixdb

A community cognee adapter that uses HelixDB as both the graph and the vector store (hybrid adapter). Requires cognee 1.4.2.

HelixDB uses pre-compiled HQL queries; the adapter deploys a generic schema (CogneeNode / CogneeEdge / CogneeVector) and a fixed set of query endpoints at initialization time. Dynamic node types are stored as a node_type property, arbitrary properties are JSON-serialized into properties_json.

Installation

pip install cognee-community-hybrid-adapter-helixdb

You need a running HelixDB instance (default localhost:6969). See the HelixDB docs for setup.

Usage

import asyncio

import cognee
from cognee_community_hybrid_adapter_helixdb import register  # noqa: F401


async def main():
    cognee.config.set_graph_db_config({"graph_database_provider": "helixdb"})
    cognee.config.set_vector_db_config({"vector_db_provider": "helixdb"})

    await cognee.add("HelixDB is a graph-vector database.")
    await cognee.cognify()

    results = await cognee.search("What is HelixDB?")
    print(results)


asyncio.run(main())
