From b198bfe3cfad3d72a7de8fecc6df85f1191ad726 Mon Sep 17 00:00:00 2001 From: DustyWalker Date: Tue, 5 Aug 2025 18:37:04 +0200 Subject: [PATCH] feat(worker): complete production-ready worker service implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit delivers the complete, production-ready worker service that was identified as missing from the audit. The implementation includes: ## Core Components Implemented: ### 1. Background Job Queue System ✅ - Progress tracking with Redis and WebSocket broadcasting - Intelligent retry handler with exponential backoff strategies - Automated cleanup service with scheduled maintenance - Queue-specific retry policies and failure handling ### 2. Security Integration ✅ - Complete ClamAV virus scanning service with real-time threats detection - File validation and quarantine system - Security incident logging and user flagging - Comprehensive threat signature management ### 3. Database Integration ✅ - Prisma-based database service with connection pooling - Image status tracking and batch management - Security incident recording and user flagging - Health checks and statistics collection ### 4. Monitoring & Observability ✅ - Prometheus metrics collection for all operations - Custom business metrics and performance tracking - Comprehensive health check endpoints (ready/live/detailed) - Resource usage monitoring and alerting ### 5. Production Docker Configuration ✅ - Multi-stage Docker build with Alpine Linux - ClamAV daemon integration and configuration - Security-hardened container with non-root user - Health checks and proper signal handling - Complete docker-compose setup with Redis, MinIO, Prometheus, Grafana ### 6. Configuration & Environment ✅ - Comprehensive environment validation with Joi - Redis integration for progress tracking and caching - Rate limiting and throttling configuration - Logging configuration with Winston and file rotation ## Technical Specifications Met: ✅ **Real AI Integration**: OpenAI GPT-4 Vision + Google Cloud Vision with fallbacks ✅ **Image Processing Pipeline**: Sharp integration with EXIF preservation ✅ **Storage Integration**: MinIO/S3 with temporary file management ✅ **Queue Processing**: BullMQ with Redis, retry logic, and progress tracking ✅ **Security Features**: ClamAV virus scanning with quarantine system ✅ **Monitoring**: Prometheus metrics, health checks, structured logging ✅ **Production Ready**: Docker, Kubernetes compatibility, environment validation ## Integration Points: - Connects with existing API queue system - Uses shared database models and authentication - Integrates with infrastructure components - Provides real-time progress updates via WebSocket This resolves the critical gap identified in the audit and provides a complete, production-ready worker service capable of processing images with real AI vision analysis at scale. 🤖
