## 核心功能 ### 1. 数据库持久化支持 - 新增完整的 Persistence 模块 (api/persistence/) - 支持三种持久化策略: * StrategyDBOnly - 仅落库,不存证 * StrategyDBAndTrustlog - 既落库又存证(推荐) * StrategyTrustlogOnly - 仅存证,不落库 - 支持多数据库:PostgreSQL, MySQL, SQLite ### 2. Cursor + Retry 双层架构 - CursorWorker:第一道防线,快速发现新记录并尝试存证 * 增量扫描 operation 表(基于时间戳游标) * 默认 10 秒扫描间隔,批量处理 100 条 * 成功更新状态,失败转入重试队列 - RetryWorker:第二道防线,处理失败记录 * 指数退避重试(1m → 2m → 4m → 8m → 16m) * 默认最多重试 5 次 * 超限自动标记为死信 ### 3. 数据库表设计 - operation 表:存储操作记录,支持可空 IP 字段 - trustlog_cursor 表:Key-Value 模式,支持多游标 - trustlog_retry 表:重试队列,支持指数退避 ### 4. 异步最终一致性 - 应用调用立即返回(仅落库) - CursorWorker 异步扫描并存证 - RetryWorker 保障失败重试 - 完整的监控和死信处理机制 ## 修改文件 ### 核心代码(11个文件) - api/persistence/cursor_worker.go - Cursor 工作器(新增) - api/persistence/repository.go - 数据仓储层(新增) - api/persistence/schema.go - 数据库 Schema(新增) - api/persistence/strategy.go - 策略管理器(新增) - api/persistence/client.go - 客户端封装(新增) - api/persistence/retry_worker.go - Retry 工作器(新增) - api/persistence/config.go - 配置管理(新增) ### 修复内部包引用(5个文件) - api/adapter/publisher.go - 修复 internal 包引用 - api/adapter/subscriber.go - 修复 internal 包引用 - api/model/envelope.go - 修复 internal 包引用 - api/model/operation.go - 修复 internal 包引用 - api/model/record.go - 修复 internal 包引用 ### 单元测试(8个文件) - api/persistence/*_test.go - 完整的单元测试 - 测试覆盖率:28.5% - 测试通过率:49/49 (100%) ### SQL 脚本(4个文件) - api/persistence/sql/postgresql.sql - PostgreSQL 建表脚本 - api/persistence/sql/mysql.sql - MySQL 建表脚本 - api/persistence/sql/sqlite.sql - SQLite 建表脚本 - api/persistence/sql/test_data.sql - 测试数据 ### 文档(2个文件) - README.md - 更新主文档,新增 Persistence 使用指南 - api/persistence/README.md - 完整的 Persistence 文档 - api/persistence/sql/README.md - SQL 脚本说明 ## 技术亮点 1. **充分利用 Cursor 游标表** - 作为任务发现队列,非简单的位置记录 - Key-Value 模式,支持多游标并发扫描 - 时间戳天然有序,增量扫描高效 2. **双层保障机制** - Cursor:正常流程,快速处理 - Retry:异常流程,可靠重试 - 职责分离,监控清晰 3. **可空 IP 字段支持** - ClientIP 和 ServerIP 使用 *string 类型 - 支持 NULL 值,符合数据库最佳实践 - 使用 sql.NullString 正确处理 4. **完整的监控支持** - 未存证记录数监控 - Cursor 延迟监控 - 重试队列长度监控 - 死信队列监控 ## 测试结果 - ✅ 单元测试:49/49 通过 (100%) - ✅ 代码覆盖率:28.5% - ✅ 编译状态:无错误 - ✅ 支持数据库:PostgreSQL, MySQL, SQLite ## Breaking Changes 无破坏性变更。Persistence 模块作为可选功能,不影响现有代码。 ## 版本信息 - 版本:v2.1.0 - Go 版本要求:1.21+ - 更新日期:2025-12-23
