# LazyDatabricks 🧱

A keyboard-first TUI for Databricks — **lazygit for your data platform**.

> Status → Logs → Action in seconds, not clicks.

## Design Principles

- **Read-first, act-second.** Default is safe visibility; destructive actions require explicit arming.
- **Spark-true, not API-true.** "Is my cluster usable?" matters more than "does the API say RUNNING?"
- **Logs are the primary artifact.** One keystroke, not seven clicks.

## Quick Start

```bash
# Install
pip install lazydatabricks

# Or from source
pip install -e ".[dev]"

# Configure (uses same env vars / .databrickscfg as Databricks SDK)
export DATABRICKS_HOST=https://adb-xxx.azuredatabricks.net
export DATABRICKS_TOKEN=dapi...

# Launch TUI (default)
lazydatabricks

# Or use specific profile
lazydatabricks --profile staging

# CLI mode (non-interactive)
lazydatabricks health      # Health snapshot
lazydatabricks clusters    # List clusters
lazydatabricks jobs        # List jobs
lazydatabricks test        # Test connection
```

## TUI Overview

LazyDatabricks provides a keyboard-driven interface with five main screens:

- **Home (h)** — Health dashboard showing workspace identity, Spark connectivity, cluster/job/warehouse summaries
- **Clusters (c)** — List and manage compute clusters with start/terminate/restart actions
- **Jobs (j)** — Three-pane hierarchy: Jobs → Runs → Detail with run now/cancel/rerun actions
- **Warehouses (w)** — SQL warehouse management with start/stop actions
- **Config** — Profile switching and connection testing

## Safety Model: Armed Mode

LazyDatabricks defaults to **READ-ONLY** mode. All destructive actions require explicitly arming:

1. Press `A` to arm (30-second timer starts)
2. Header shows red "ARMED (Xs)" countdown
3. Execute destructive action (e.g., `t` to terminate cluster)
4. System auto-disarms after 30 seconds

Destructive actions include:
- Cluster: start, terminate, restart
- Job: run now, cancel, rerun
- Warehouse: start, stop

## Configuration

LazyDatabricks uses the same configuration as the Databricks SDK:

1. **Environment variables** (highest priority)
   ```bash
   export DATABRICKS_HOST=https://adb-xxx.azuredatabricks.net
   export DATABRICKS_TOKEN=dapi...
   export DATABRICKS_CLUSTER_ID=0123-456789-abcdef  # optional
   ```

2. **~/.databrickscfg profiles**
   ```ini
   [DEFAULT]
   host = https://adb-xxx.azuredatabricks.net
   token = dapi...
   cluster_id = 0123-456789-abcdef

   [staging]
   host = https://adb-yyy.azuredatabricks.net
   token = dapi...
   ```

3. **CLI flags**
   ```bash
   lazydatabricks --host https://... --token dapi... --cluster-id 0123...
   lazydatabricks --profile staging
   ```

## Development

```bash
# Install with dev dependencies
pip install -e ".[dev]"

# Run tests
pytest tests/ -v

# Type checking
mypy src/lazydatabricks

# Linting
ruff check src/lazydatabricks
```

## Requirements

- Python 3.10+
- Databricks workspace with API access
