在導入第 5 版 (V5) 架構之前，請確認 V5 動態饋給符合下列規定：
- 更新任何商家欄位時，商家
last_update_timestamp 會隨之變更
- 商家 ID 在所有 V5 增量代碼中均不得重複；也就是說，商家 ID 只能參照單一商家
- 系統會將多個商家 ID 視為單一商家 ID，視為單一商家更新
- 更新任何評論欄位時，查看
last_update_timestamp 變更
- 所有 V5 漸進式評論 ID 均不重複，也就是說，評論 ID 應僅參照單一評論
- 單一評論 ID 的多個審查項目會視為單一評論更新
- 評論 ID 只能附加到一個商家 ID
- 建立時間戳記不會改變
- 更新時間 (即
last_update_timestamp) 必須等於或晚於建立時間 (亦即 create_timestamp)
