-- 迁移：移除废弃的 dws_member_recall_index 表及 RLS 视图
|
||
-- 日期: 2026-03-20
|
||
-- 原因: RecallIndexTask 已于 2026-02-13 被 WBI+NCI 替代，但表和视图的 DDL
|
||
-- 在 2026-02-19 schema 重命名（billiards_dws → dws）时残留至今。
|
||
-- 表中无有效数据（ETL 任务已删除），属于孤儿对象。
|
||
-- 影响: 无下游消费者依赖此表数据（后端 recall 维度已改用 v_dws_member_winback_index）
|
||
-- 回滚: 从 git 历史恢复 DDL 定义并重建表和视图
|
||
-- =============================================================================
