* AdaptiveBatchScheduler: 核心调度引擎 * 自适应批次: 10-100动态调整，根据负载优化 * 优先级队列: LOW/NORMAL/HIGH/URGENT四级优先级 * 智能等待: 50-200ms动态调整，平衡吞吐和延迟 * 超时保护: 防止操作长时间阻塞 * 拥塞控制: 实时监控队列状态，自动调节 - 性能优化算法: * 批次自适应: congestion > 0.7 增大批次 * 等待时间调整: duration > 2*wait 增加等待 * 缓存集成: 5秒TTL，减少重复查询 - 批量执行能力: * SELECT: 智能合并相似查询 * INSERT: 批量插入，减少事务开销 * UPDATE/DELETE: 单条执行但复用会话 - 统计监控: * 吞吐量: 总操作数/批处理数 * 性能: 平均批次大小/执行时间 * 质量: 缓存命中率/超时率/错误率 * 拥塞: 实时拥塞评分(0-1) 优化层三大组件全部完成: 1. MultiLevelCache - L1+L2两级缓存 2. DataPreloader - 智能预加载引擎 3. AdaptiveBatchScheduler - 自适应批处理 预期性能提升: - 查询响应: 减少60% (缓存+预加载) - 写入吞吐: 提升300% (批量处理) - 数据库负载: 降低50% (连接复用+批处理) --- src/common/database/optimization/__init__.py | 15 +

adapter.py (370行): 向后兼容适配器 * 完全兼容旧API签名: db_query, db_save, db_get, store_action_info * 支持MongoDB风格操作符 (\, \, \) * 内部使用新架构 (QueryBuilder + CRUDBase) * 保持返回dict格式不变 * MODEL_MAPPING: 25个模型映射 - __init__.py: 导出兼容API 更新database/__init__.py: - 导出核心层 (engine, session, models, migration) - 导出优化层 (cache, preloader, batch_scheduler) - 导出API层 (CRUD, Query, 业务API) - 导出Utils层 (装饰器, 监控) - 导出兼容层 (db_query, db_save等) 核心特性 ======== 类型安全: Generic[T]提供完整类型推断 缓存透明: 自动缓存，用户无需关心 批处理透明: 可选批处理，自动优化高频写入 链式查询: 流畅的API设计 业务封装: 常用操作封装成便捷函数 向后兼容: 兼容层保证现有代码无缝迁移 性能监控: 完整的指标收集和报告 统计数据 ======== - 新增文件: 7个 -

return result + + # 缓存未命中，执行查询 + result = await execute_database_query() + + # 写入缓存 + await cache.set("my_key", result) + + return result +``` + +### 3. 缓存失效 + +更新数据后需要主动使缓存失效： + +```python +from

+### 3. 及时失效 + +- **写入时失效**: 数据更新后立即删除缓存 +- **批量失效**: 使用通配符或前缀批量删除相关缓存 +- **惰性失效**: 依赖 TTL 自动过期（适用于非关键数据） + +### 4. 监控缓存效果 + +定期检查缓存统计： +- 命中率 > 70% - 缓存效果良好 +- 命中率 50-70% - 可以优化 TTL 或缓存策略 +- 命中率 <
