- NullPool 改為 QueuePool 連線池 - pool_size=5, max_overflow=10, pool_recycle=1800 - pool_pre_ping 確保連線有效性 - 新增連線池監控事件 (checkout/checkin/invalidate/connect) - 新增 keep-alive 機制 (每 5 分鐘 ping) - 新增 dispose_engine() 清理函數 - Gunicorn worker_exit hook 自動清理連線 - 降低 graceful_timeout 至 10 秒加速重啟 - 降低 tcp_connect_timeout 至 10 秒減少等待 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
