|
||
会员来店明细任务
|
||
|
||
功能说明：
|
||
以"会员+订单"为粒度，记录每次来店消费明细
|
||
|
||
数据来源：
|
||
- dwd_settlement_head: 结账单头表
|
||
- dwd_assistant_service_log: 助教服务流水
|
||
- dim_member: 会员维度
|
||
- dim_table: 台桌维度
|
||
- cfg_area_category: 区域分类映射
|
||
|
||
目标表：
|
||
billiards_dws.dws_member_visit_detail
|
||
|
||
更新策略：
|
||
- 更新频率：每日增量更新
|
||
- 幂等方式：delete-before-insert（按日期窗口）
|
||
|
||
业务规则：
|
||
- 散客处理：member_id=0 不进入此表
|
||
- 区域分类：使用cfg_area_category映射
|
||
- 助教服务：以JSON格式存储多个助教的服务明细
