# Ladybug Dataset Database Handler

> Handler for using Ladybug, Cognee's embedded graph store, in multi-user mode.

> [!WARNING]
>
> Make sure that `ENABLE_BACKEND_ACCESS_CONTROL` in your `.env` file is **NOT** set to `False`.
> Multi-user mode is enabled by default, therefore `ENABLE_BACKEND_ACCESS_CONTROL=True` by default.

The Ladybug adapter is one of Cognee's core graph adapters, along with Neo4j. Ladybug was previously called Kuzu; the handler and provider are still registered under both names, so `kuzu` keeps working wherever `ladybug` is shown below.

## Installation

Ladybug is part of Cognee's core dependencies, so no extra installation steps are required.

## Setup and Usage

Since Ladybug is a file-based database, and its handler is registered in Cognee by default,
all that needs to be set is the information about the provider, and to let Cognee know which
handler you are using:

```dotenv theme={null}
GRAPH_DATABASE_PROVIDER="ladybug"
GRAPH_DATASET_DATABASE_HANDLER="ladybug"
```

Graph files are stored by default in the .cognee\_system folder (within the Cognee package), with each dataset assigned its own persistent graph file.
