+# Query Sidecar Service Integration
+
+This document describes the Node.js Query Sidecar Service integration that eliminates stale QueryObject issues in Superset Alerts & Reports.
+
+## Problem Statement
+
+Previously, Superset stored QueryObjects in the database after chart visualization logic transformed `form_data` into QueryObject format. This approach had a critical flaw: when the JavaScript visualization code changed, the stored QueryObjects became stale, causing Alerts & Reports to use outdated query logic.
+
+## Solution
+
+The Query Sidecar Service provides a Node.js service that computes QueryObjects from `form_data` on-demand using the same logic as the frontend, ensuring:
+
+- **No stale data**: QueryObjects are computed fresh every time
+- **Consistency**: Uses identical logic to the Superset frontend
+- **Backward compatibility**: Falls back to legacy screenshot method if sidecar is unavailable
+
+## Architecture
+
+```mermaid
+graph TB
+ A[Superset Frontend] --> B[form_data]
+ B --> C[Chart Database Record]
+
+ D[Alerts & Reports] --> E{Sidecar Available?}
+ E -->|Yes| F[Query Sidecar Service]
+ E -->|No| G[Legacy Screenshot Method]
+
+ F --> H[buildQueryObject.ts Logic]
+ H --> I[Fresh QueryObject]
+
+ C --> F
+ I --> J[Chart Data API]
+ G --> J
+```
+
+## Components
+
+### 1. Node.js Sidecar Service (`sidecar-node/`)
+
+Located in `sidecar-node/`, this service provides:
+
+- **REST API**: `POST /api/v1/query-object` to transform form_data
+- **Type Safety**: Full TypeScript implementation with Superset type definitions
+- **Frontend Compatibility**: Uses identical logic from `superset-ui-core`
+- **Health Checks**: `/health` endpoint for monitoring
+- **Docker Support**: Production-ready containerization
+
+Key files:
+- `src/query/buildQueryObject.ts` - Main transformation logic
+- `src/types/index.ts` - TypeScript type definitions
+- `src/routes/queryObject.ts` - REST API endpoints
+- `Dockerfile` - Container configuration
+
+### 2. Python Client (`superset/utils/query_sidecar.py`)
+
+Python client library that:
+
+- **HTTP Communication**: Handles requests to the sidecar service
+- **Error Handling**: Robust error handling with fallback mechanisms
+- **QueryObject Creation**: Converts responses to Superset QueryObject instances
+- **Configuration**: Configurable timeouts and URLs
+
+### 3. Reports Integration (`superset/commands/report/execute.py`)
+
+Updated report execution logic:
+
+- **Primary Method**: Uses sidecar service to generate fresh QueryObjects
+- **Fallback Method**: Falls back to legacy screenshot method on failure
+- **Configuration**: Controlled by `QUERY_SIDECAR_ENABLED` setting
+
+## Setup and Configuration
+
+### 1. Deploy the Sidecar Service
+
+#### Development
+```bash
+cd sidecar-node
+npm install
+npm run dev
+```
+
+#### Production with Docker
+```bash
+cd sidecar-node
+docker build -t superset-query-sidecar .
+docker run -p 3001:3001 superset-query-sidecar
+```
+
+#### Production with Docker Compose
+```bash
+docker-compose -f docker-compose.sidecar.yml up -d
+```
+
+### 2. Configure Superset
+
+Add to your Superset configuration:
+
+```python
+# Enable sidecar service integration
+QUERY_SIDECAR_ENABLED = True
+
+# Sidecar service URL
+QUERY_SIDECAR_BASE_URL = "http://localhost:3001"
+
+# Request timeout (seconds)
+QUERY_SIDECAR_TIMEOUT = 10
+```
+
+#### Production Configuration Example
+```python
+QUERY_SIDECAR_ENABLED = True
+QUERY_SIDECAR_BASE_URL = "http://superset-query-sidecar:3001"
+QUERY_SIDECAR_TIMEOUT = 30
+```
+
+### 3. Verify Integration
+
+#### Check Sidecar Health
+```bash
+curl http://localhost:3001/health
+```
+
+#### Test API Endpoint
+```bash
+curl -X POST http://localhost:3001/api/v1/query-object \
+ -H "Content-Type: application/json" \
+ -d '{
+ "form_data": {
+ "datasource": "1__table",
+ "viz_type": "table",
+ "metrics": ["count"],
+ "columns": ["name"]
+ }
+ }'
+```
+
+## API Reference
+
+### POST /api/v1/query-object
+
+Transforms `form_data` into a QueryObject.
+
+**Request:**
+```json
+{
+ "form_data": {
+ "datasource": "1__table",
+ "viz_type": "table",
+ "metrics": ["count"],
+ "columns": ["name"],
+ "time_range": "No filter"
+ },
+ "query_fields": {
+ "x": "columns",
+ "y": "metrics"
+ }
+}
+```
+
+**Response:**
+```json
+{
+ "query_object": {
+ "metrics": ["count"],
+ "columns": ["name"],
+ "time_range": "No filter",
+ "filters": [],
+ "extras": {},
+ "row_limit": undefined,
+ "order_desc": true
+ }
+}
+```
+
+**Error Response:**
+```json
+{
+ "error": "form_data must include datasource and viz_type"
+}
+```
+
+### GET /health
+
+Returns service health status.
+
+**Response:**
+```json
+{
+ "status": "healthy",
+ "timestamp": "2023-12-01T12:00:00.000Z",
+ "version": "1.0.0"
+}
+```
+
+## Error Handling
+
+The integration includes comprehensive error handling:
+
+### Sidecar Service Errors
+- **Connection Errors**: Falls back to legacy screenshot method
+- **Timeout Errors**: Configurable timeout with fallback
+- **Service Errors**: Logs errors and uses fallback method
+
+### Configuration
+```python
+# Disable sidecar to use legacy method only
+QUERY_SIDECAR_ENABLED = False
+
+# Increase timeout for slow networks
+QUERY_SIDECAR_TIMEOUT = 30
+```
+
+## Migration Strategy
+
+### Phase 1: Parallel Running
+1. Deploy sidecar service alongside existing Superset
+2. Enable `QUERY_SIDECAR_ENABLED = True`
+3. Monitor logs for any fallback usage
+
+### Phase 2: Validation
+1. Compare QueryObjects generated by sidecar vs stored versions
+2. Verify Alerts & Reports work correctly
+3. Monitor performance metrics
+
+### Phase 3: Full Migration
+1. Remove dependency on stored query_context (future)
+2. Optimize sidecar performance
+3. Scale sidecar service as needed
+
+## Testing
+
+### Node.js Service Tests
+```bash
+cd sidecar-node
+npm test
+npm run test:watch
+```
+
+### Python Integration Tests
+```bash
+pytest tests/unit_tests/utils/test_query_sidecar.py
+pytest tests/unit_tests/commands/report/test_execute_sidecar.py
+```
+
+### Integration Testing
+1. Create test alerts/reports
+2. Verify they execute with fresh QueryObjects
+3. Test fallback behavior by stopping sidecar service
+
+## Monitoring and Logging
+
+### Service Monitoring
+- Health check endpoint: `GET /health`
+- Docker health checks included
+- Prometheus metrics (future enhancement)
+
+### Superset Logging
+The integration adds detailed logging:
+
+```python
+logger.info("Successfully generated query context via sidecar for chart %s", chart_id)
+logger.warning("Failed to generate query context via sidecar service: %s. Falling back to screenshot method.", error)
+```
+
+### Log Levels
+- `INFO`: Successful sidecar operations
+- `WARNING`: Fallback to legacy method
+- `ERROR`: Critical failures
+
+## Performance Considerations
+
+### Latency
+- Sidecar adds ~10-50ms per request
+- Network latency between services
+- Configurable timeout prevents blocking
+
+### Scaling
+- Sidecar service is stateless and can be horizontally scaled
+- Consider load balancing for high-volume deployments
+- Cache QueryObjects if needed (future enhancement)
+
+### Resource Usage
+- Node.js service: ~50-100MB RAM
+- CPU usage minimal for typical workloads
+- Network bandwidth: ~1-10KB per request
+
+## Future Enhancements
+
+1. **Caching**: Add Redis/Memcached for QueryObject caching
+2. **Metrics**: Prometheus metrics for monitoring
+3. **Load Balancing**: Support multiple sidecar instances
+4. **Query Optimization**: Optimize query generation performance
+5. **Database Cleanup**: Remove stored query_context column (breaking change)
+
+## Troubleshooting
+
+### Common Issues
+
+#### Sidecar Service Not Starting
+```bash
+# Check logs
+docker logs superset-query-sidecar
+
+# Verify port availability
+netstat -tlnp | grep 3001
+```
+
+#### Connection Errors
+```bash
+# Test connectivity
+curl http://localhost:3001/health
+
+# Check Superset logs
+grep -i "sidecar" /var/log/superset/superset.log
+```
+
+#### Fallback Behavior
+```bash
+# Check if sidecar is being bypassed
+grep -i "falling back" /var/log/superset/superset.log
+```
+
+### Configuration Issues
+- Verify `QUERY_SIDECAR_BASE_URL` is correct
+- Check network connectivity between services
+- Ensure sidecar service is healthy
+
+### Performance Issues
+- Increase `QUERY_SIDECAR_TIMEOUT` if needed
+- Monitor sidecar service resource usage
+- Consider scaling sidecar service
+
+## Security Considerations
+
+### Network Security
+- Run sidecar service on internal network
+- Use HTTPS in production environments
+- Configure proper firewall rules
+
+### Input Validation
+- Sidecar service validates all inputs
+- Superset client validates responses
+- No raw SQL execution in sidecar service
+
+### Access Control
+- Service-to-service authentication (future)
+- Network-level access controls
+- Audit logging of sidecar requests
