# Databricks Genie

Create and query Databricks Genie Spaces - natural language interfaces for SQL-based data
exploration.

## Overview

Genie Spaces allow users to ask natural language questions about structured data in Unity Catalog.
The system translates questions into SQL queries, executes them on a SQL warehouse, and presents
results conversationally.

## When to Use This Skill

Use this skill when:

- Creating a new Genie Space for data exploration
- Adding sample questions to guide users
- Connecting Unity Catalog tables to a conversational interface
- Asking questions to a Genie Space programmatically (Conversation API)

## MCP Tools

### Space Management

| Tool                     | Purpose                                 |
| ------------------------ | --------------------------------------- |
| `list_genie`             | List all Genie Spaces accessible to you |
| `create_or_update_genie` | Create or update a Genie Space          |
| `get_genie`              | Get Genie Space details                 |
| `delete_genie`           | Delete a Genie Space                    |

### Conversation API

| Tool                 | Purpose                                            |
| -------------------- | -------------------------------------------------- |
| `ask_genie`          | Ask a question to a Genie Space, get SQL + results |
| `ask_genie_followup` | Ask follow-up question in existing conversation    |

### Supporting Tools

| Tool                | Purpose                                       |
| ------------------- | --------------------------------------------- |
| `get_table_details` | Inspect table schemas before creating a space |
| `execute_sql`       | Test SQL queries directly                     |

## Quick Start

### 1. Inspect Your Tables

Before creating a Genie Space, understand your data:

```python
get_table_details(
    catalog="my_catalog",
    schema="sales",
    table_stat_level="SIMPLE"
)
```

### 2. Create the Genie Space

```python
create_or_update_genie(
    display_name="Sales Analytics",
    table_identifiers=[
        "my_catalog.sales.customers",
        "my_catalog.sales.orders"
    ],
    description="Explore sales data with natural language",
    sample_questions=[
        "What were total sales last month?",
        "Who are our top 10 customers?"
    ]
)
```

### 3. Ask Questions (Conversation API)

```python
ask_genie(
    space_id="your_space_id",
    question="What were total sales last month?"
)
# Returns: SQL, columns, data, row_count
```

## Workflow

```
1. Inspect tables    → get_table_details
2. Create space      → create_or_update_genie
3. Query space       → ask_genie (or test in Databricks UI)
4. Curate (optional) → Use Databricks UI to add instructions
```

## Prerequisites

Before creating a Genie Space:

1. **Tables in Unity Catalog** - Bronze/silver/gold tables with the data
2. **SQL Warehouse** - A warehouse to execute queries (auto-detected if not specified)

### Creating Tables

Use these skills in sequence:

1. `synthetic-data-generation` - Generate raw parquet files
2. `spark-declarative-pipelines` - Create bronze/silver/gold tables

## Common Issues

| Issue                      | Solution                                                                 |
| -------------------------- | ------------------------------------------------------------------------ |
| **No warehouse available** | Create a SQL warehouse or provide `warehouse_id` explicitly              |
| **Poor query generation**  | Add instructions and sample questions that reference actual column names |
| **Slow queries**           | Ensure warehouse is running; use OPTIMIZE on tables                      |
