Pooling and Management + +This document describes the WebSocket connection pooling system implemented in the Delphi Database application. + +## Overview + +The WebSocket pooling system provides: +- **Connection Pooling**: Efficient management of multiple concurrent WebSocket connections +- **Automatic Cleanup**: Removal of stale and inactive connections +- **Resource Management**: Prevention of memory leaks and resource exhaustion +- **Health Monitoring**: Connection health checks and heartbeat management +- **Topic-Based Broadcasting**: Efficient message distribution to subscriber groups +- **Admin Management**: Administrative tools for monitoring and managing connections + +## Architecture + +### Core Components + +1. **WebSocketPool** (`app/services/websocket_pool.py`) + - Central connection pool manager + - Handles connection lifecycle + - Provides broadcasting and cleanup functionality + +2. **WebSocketManager** (`app/middleware/websocket_middleware.py`) + - High-level interface for WebSocket operations + - Handles authentication and message processing + - Provides convenient decorators and utilities + +3. **Admin API** (`app/api/admin.py`) + - Administrative endpoints for monitoring and management + - Connection statistics and health metrics + - Manual cleanup and broadcasting tools + +### Key Features + +#### Connection Management +- **Unique Connection IDs**: Each connection gets a unique identifier +- **User Association**: Connections can be associated with authenticated users +- **Topic Subscriptions**: Connections can subscribe to multiple topics +- **Metadata Storage**: Custom metadata can be attached to connections + +#### Automatic Cleanup +- **Stale Connection Detection**: Identifies inactive connections +- **Background Cleanup**: Automatic removal of stale connections +- **Failed Message Cleanup**: Removes connections that fail to receive messages +- **Configurable Timeouts**: Customizable timeout settings + +#### Health Monitoring +- **Heartbeat System**: Regular health checks via ping/pong +- **Connection State Tracking**: Monitors connection lifecycle states +- **Error Counting**: Tracks connection errors and failures +- **Activity Monitoring**: Tracks last activity timestamps + +#### Broadcasting System +- **Topic-Based**: Efficient message distribution by topic +- **User-Based**: Send messages to all connections for a specific user +- **Selective Exclusion**: Exclude specific connections from broadcasts +- **Message Types**: Structured message format with type classification + +## Configuration + +### Pool Settings + +```python +# Initialize WebSocket pool with custom settings +await initialize_websocket_pool( + cleanup_interval=60, # Cleanup check interval (seconds) + connection_timeout=300, # Connection timeout (seconds) + heartbeat_interval=30, # Heartbeat interval (seconds) + max_connections_per_topic=1000, # Max connections per topic + max_total_connections=10000 # Max total connections +) +``` + +### Environment Variables + +The pool respects the following configuration from `app/config.py`: +- Database connection settings for user authentication +- Logging configuration for structured logging +- Security settings for token verification + +## Usage Examples + +### Basic WebSocket Endpoint + +```python +from app.middleware.websocket_middleware import websocket_endpoint + +@router.websocket("/ws/notifications") +@websocket_endpoint(topics={"notifications"}, require_auth=True) +async def notifications_endpoint(websocket: WebSocket, connection_id: str, manager: WebSocketManager): + # Connection is automatically managed + # Authentication is handled automatically + # Cleanup is handled automatically + pass +``` + +### Manual Connection Management + +```python +from app.middleware.websocket_middleware import get_websocket_manager + +@router.websocket("/ws/custom") +async def custom_endpoint(websocket: WebSocket): + manager = get_websocket_manager() + + async def handle_message(connection_id: str, message: WebSocketMessage): + if message.type == "chat": + await manager.broadcast_to_topic( + topic="chat_room", + message_type="chat_message", + data=message.data + ) + + await manager.handle_connection( + websocket=websocket, + topics={"chat_room"}, + require_auth=True, + message_handler=handle_message + ) +``` + +### Broadcasting Messages + +```python +from app.middleware.websocket_middleware import get_websocket_manager + +async def send_notification(user_id: int, message: str): + manager = get_websocket_manager() + + # Send to specific user + await manager.send_to_user( + user_id=user_id, + message_type="notification", + data={"message": message} + ) + +async def broadcast_announcement(message: str): + manager = get_websocket_manager() + + # Broadcast to all subscribers of a topic + await manager.broadcast_to_topic( + topic="announcements", + message_type="system_announcement", + data={"message": message} + ) +``` + +## Administrative Features + +### WebSocket Statistics + +```bash +GET /api/admin/websockets/stats +``` + +Returns comprehensive statistics about the WebSocket pool: +- Total and active connections +- Message counts (sent/failed) +- Topic distribution +- Connection states +- Cleanup statistics + +### Connection Management + +```bash +# List all connections +GET /api/admin/websockets/connections + +# Filter connections +GET /api/admin/websockets/connections?user_id=123&topic=notifications + +# Get specific connection details +GET /api/admin/websockets/connections/{connection_id} + +# Disconnect connections +POST /api/admin/websockets/disconnect +{ + "user_id": 123, // or connection_ids, or topic + "reason": "maintenance" +} + +# Manual cleanup +POST /api/admin/websockets/cleanup + +# Broadcast message +POST /api/admin/websockets/broadcast +{ + "topic": "announcements", + "message_type": "admin_message", + "data": {"message": "System maintenance in 5 minutes"} +} +``` + +## Message Format + +All WebSocket messages follow a structured format: + +```json +{ + "type": "message_type", + "topic": "optional_topic", + "data": { + "key": "value" + }, + "timestamp": "2023-01-01T12:00:00Z", + "error": "optional_error_message" +} +``` + +### Standard Message Types + +- `ping`/`pong`: Heartbeat messages +- `welcome`: Initial connection message +- `subscribe`/`unsubscribe`: Topic subscription management +- `data`: General data messages +- `error`: Error notifications +- `heartbeat`: Automated health checks + +## Security + +### Authentication +- Token-based authentication via query parameters or headers +- User session validation against database +- Automatic connection termination for invalid credentials + +### Authorization +- Admin-only access to management endpoints +- User-specific connection filtering +- Topic-based access control (application-level) + +### Resource Protection +- Connection limits per topic and total +- Automatic cleanup of stale connections +- Rate limiting integration (via existing middleware) + +## Monitoring and Debugging + +### Structured Logging +All WebSocket operations are logged with structured data: +- Connection lifecycle events +- Message broadcasting statistics +- Error conditions and cleanup actions +- Performance metrics + +### Health Checks +- Connection state monitoring +- Stale connection detection +- Message delivery success rates +- Resource usage tracking + +### Metrics +The system provides metrics for: +- Active connection count +- Message throughput +- Error rates +- Cleanup efficiency + +## Integration with Existing Features + +### Billing API Integration +The existing billing WebSocket endpoint has been migrated to use the pool: +- Topic: `batch_progress_{batch_id}` +- Automatic connection management +- Improved reliability and resource usage + +### Future Integration Opportunities +- Real-time search result updates +- Document processing notifications +- User activity broadcasts +- System status updates + +## Performance Considerations + +### Scalability +- Connection pooling reduces resource overhead +- Topic-based

connection storage +- Minimal memory footprint per connection + +### Network Efficiency +- Heartbeat system prevents connection timeouts +- Failed connection detection and cleanup +- Structured message format reduces parsing overhead + +## Troubleshooting + +### Common Issues + +1. **Connections not cleaning up** + - Check cleanup interval configuration + - Verify connection timeout settings + - Monitor stale connection detection + +2. **Messages not broadcasting** + - Verify topic subscription + - Check connection state + - Review authentication status + +3. **High memory usage** + - Monitor connection count limits + - Check for stale connections + - Review cleanup efficiency + +### Debug Tools + +1. **Admin API endpoints** for real-time monitoring +2. **Structured logs** for detailed operation tracking +3. **Connection metrics** for performance analysis +4. **Health check endpoints** for system status + +## Testing + +Comprehensive test suite covers: +- Connection pool functionality +- Message broadcasting +- Cleanup mechanisms +- Health monitoring +- Admin API operations +- Integration scenarios +- Stress testing + +Run tests with: +```bash +pytest
