# The Discoverer

[![GitHub](https://img.shields.io/badge/GitHub-Repository-blue)](https://github.com/khannoussi-malek/the-discoverer)

AI-powered database discovery and query agent supporting multiple SQL and NoSQL databases with vector database optimization for schema and content.

## Author

- GitHub: [@khannoussi-malek](https://github.com/khannoussi-malek)
- LinkedIn: [khannoussi-malek](https://www.linkedin.com/in/khannoussi-malek/)

## Features

- **Multi-Database Support**: PostgreSQL, MySQL, MongoDB, SQLite (extensible to Cassandra, Elasticsearch)
- **Vector Database**: Fast schema and content discovery using Qdrant
- **AI-Powered Queries**: Natural language to SQL/NoSQL query generation with pattern matching
- **Performance Optimized**: 
  - Multi-layer caching (in-memory → Redis → Vector DB)
  - Parallel query execution across databases
  - Connection pooling per database
  - Batch operations for embeddings
- **Hybrid Query Routing**: Smart routing between content vector DB and schema-based queries
- **Visualization**: Automatic chart generation from query results using Plotly
- **Clean Architecture**: KISS, DRY principles with design patterns (Repository, Adapter, Factory, Strategy)

## Quick Start

### Prerequisites

- Python 3.10+
- Docker and Docker Compose (for services)
- OpenAI API key (for LLM features)

### Installation

1. Clone the repository:
```bash
git clone https://github.com/khannoussi-malek/the-discoverer.git
cd the-discoverer
```

2. Install dependencies:
```bash
pip install -r requirements.txt
```

3. Set up environment variables:
```bash
cp .env.example .env
# Edit .env with your configuration
```

4. Start services with Docker Compose:
```bash
docker-compose up -d
```

5. Run the application:
```bash
uvicorn src.api.main:app --reload
```

6. (Optional) Install CLI tool:
```bash
pip install -e .
# Or use directly: python -m src.cli.main
```

## CLI Usage

The Discoverer includes a command-line interface for easy interaction:

```bash
# Register a database
discoverer register --database-id db1 --type postgresql --host-db localhost --port 5432 --database mydb --user postgres --password pass

# List databases
discoverer list-databases

# Execute a query
discoverer query "Count all users" --format table

# Check health
discoverer health

# Sync database schema
discoverer sync db1

# Export query result
discoverer export query_id --format csv
```

## Configuration

### Environment Variables

See `.env.example` for all available configuration options.

### Database Configuration

Configure databases in `config/databases.yaml` (copy from `config/databases.yaml.example`).

## API Documentation

Once running, visit:
- API Docs: http://localhost:8000/docs
- ReDoc: http://localhost:8000/redoc

### Quick Start Example

1. **Register a database:**
```bash
curl -X POST "http://localhost:8000/api/discovery/databases" \
  -H "Content-Type: application/json" \
  -d '{
    "id": "my_db",
    "type": "postgresql",
    "name": "My Database",
    "host": "localhost",
    "port": 5432,
    "database": "mydb",
    "user": "user",
    "password": "password"
  }'
```

2. **Execute a query:**
```bash
curl -X POST "http://localhost:8000/api/query/execute" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Show me all customers"
  }'
```

3. **Index table content:**
```bash
curl -X POST "http://localhost:8000/api/indexing/databases/my_db/tables/customers/index?strategy=smart"
```
