檔案交易事件的狀態

描述一筆檔案操作相對於資料庫交易的生命週期位置。sweep（下一階段）依此判定孤兒：

  • CREATED 過 grace 仍無 CONFIRMED/ROLLED_BACK → 模糊（可能 commit 後崩潰）→ 報告，不自動刪
  • ROLLED_BACK 但實體檔案仍在 → 補償刪除失敗 → 可證明孤兒 → 安全刪除
  • CONFIRMED 但實體檔案不存在 → 延後刪除失敗或外部刪除 → 報告
  • DELETE_PENDING 久未變 DELETED → afterCommit 未跑到（崩潰）→ 重試刪除

  • Enum Constant Details

    • CREATED

      public static final JournalState CREATED
      persist/store 的實體操作已完成，但業務交易尚未 commit

    • CONFIRMED

      public static final JournalState CONFIRMED
      業務交易已 commit，檔案被合法參照（無交易時的操作也直接記為此狀態）

    • ROLLED_BACK

      public static final JournalState ROLLED_BACK
      業務交易 rollback，補償刪除已觸發

    • DELETE_PENDING

      public static final JournalState DELETE_PENDING
      delete 已登記，延到 commit 後才執行

    • DELETED
