Change: Optimize WebSocket Database Sessions for Production

Status: ✅ COMPLETED - Ready for archive

Why

目前 WebSocket 連線在整個生命週期中持有單一資料庫 Session，造成連線池快速耗盡。當 50+ 用戶同時在線時，15 個連線池容量無法支撐，導致資料庫操作阻塞或失敗。此外，sequence_number 的計算存在競爭條件，可能導致訊息順序錯誤。

What Changes

  • BREAKING: 移除 WebSocket 連線的長期 Session 持有模式
  • 改用短期 Session 模式：每次 DB 操作獨立取得連線
  • 增加連線池容量配置（可透過環境變數調整）
  • 修復 sequence_number 競爭條件（使用資料庫層級鎖定）
  • 新增環境變數支援動態調整連線池參數

Impact

  • Affected specs: realtime-messaging
  • Affected code:
    • app/core/database.py - 連線池配置
    • app/core/config.py - 新增環境變數
    • app/modules/realtime/router.py - WebSocket Session 管理
    • app/modules/realtime/services/message_service.py - Sequence 鎖定
    • .env.example - 新增配置說明
    • .env - 同步更新目前使用的環境變數檔案
