- 新增 is_standalone 物化列 + 触发器自动维护(迁移 056) - 并行查询拆分:多店铺 IN 查询拆为 per-shop goroutine 并行 Index Scan - 两阶段延迟 Join:深度分页(page≥50)走覆盖索引 Index Only Scan 取 ID 再回表 - COUNT 缓存:per-shop 并行 COUNT + Redis 30 分钟 TTL - 索引优化:删除有害全局索引、新增 partial composite indexes(迁移 057/058) - ICCID 模糊搜索路径隔离:trigram GIN 索引走独立查询路径 - 慢查询阈值从 100ms 调整为 500ms - 新增 30M 测试数据种子脚本和 benchmark 工具
