会员消费汇总任务
|
||||
|
||||
功能说明：
|
||||
以"会员"为粒度，统计消费行为和滚动窗口指标
|
||||
|
||||
数据来源：
|
||||
- dwd_settlement_head: 结账单头表
|
||||
- dim_member: 会员维度
|
||||
- dim_member_card_account: 会员卡账户
|
||||
|
||||
目标表：
|
||||
billiards_dws.dws_member_consumption_summary
|
||||
|
||||
更新策略：
|
||||
- 更新频率：每日更新
|
||||
- 幂等方式：delete-before-insert（按统计日期）
|
||||
|
||||
业务规则：
|
||||
- 散客处理：member_id=0 不进入此表
|
||||
- 滚动窗口：7/10/15/30/60/90天
|
||||
- 卡余额：区分储值卡（现金卡）和赠送卡
