🎯 SESSION POOLING PERFORMANCE BREAKTHROUGH! ✅ Critical Issues Fixed: - Eliminated multiple PrismaClient instances across schedulers - Fixed connection pool exhaustion risk in processing modules - Implemented singleton pattern for all database connections - Added graceful shutdown and connection cleanup 🚀 Enhanced Pooling Features: - Dual-mode connection pooling (standard + enhanced) - PostgreSQL native pooling with @prisma/adapter-pg - Advanced connection monitoring and health checks - Configurable pool limits and timeouts via environment variables - Real-time connection statistics and metrics 📊 Performance Optimizations: - Single shared connection pool across all schedulers - Configurable connection limits (DATABASE_CONNECTION_LIMIT=20) - Idle timeout management (DATABASE_POOL_TIMEOUT=10) - Connection cycling and health validation - Process termination signal handling 🛠️ New Infrastructure: - lib/database-pool.ts - Advanced pooling configuration - app/api/admin/database-health/route.ts - Connection monitoring - Enhanced lib/prisma.ts with dual-mode support - Comprehensive documentation in docs/database-connection-pooling.md - Graceful shutdown handling in lib/schedulers.ts 🎛️ Environment Configuration: - USE_ENHANCED_POOLING=true for production optimization - DATABASE_CONNECTION_LIMIT for pool size control - DATABASE_POOL_TIMEOUT for idle connection management - Automatic enhanced pooling in production environments 📈 Expected Impact: - Eliminates connection pool exhaustion under load - Reduces memory footprint from idle connections - Improves scheduler performance and reliability - Enables better resource monitoring and debugging - Supports horizontal scaling with proper connection management Production-ready connection pooling with monitoring and health checks!
