质量检查核对清单
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
在实施版本 5 (V5) 架构之前，请确保您的 V5 Feed 符合以下要求：
- 当任何商家字段更新时，商家
last_update_timestamp 会发生变化
- 商家 ID 在所有 V5 增量中都是唯一的，也就是说，商家 ID 应仅引用一个商家
- 多个商家 ID 若引用一个商家 ID，则视为对一个商家的更新
- 当任何审核字段更新时，查看
last_update_timestamp 项变更
- 评价 ID 在所有 V5 增量中具有唯一性，也就是说，评价 ID 应仅引用一条评价
- 单个评价 ID 的多个评价条目被视为对单个评价的更新
- 评价 ID 只能附加到单个商家 ID
- 创建时间戳保持不变
- 更新时间（即
last_update_timestamp）必须与创建时间相同或之后（即 create_timestamp）
