+### 3.5 集成架构设计
+
+#### 插件接口设计
+
+```c
+// 备份插件接口
+typedef struct {
+    // 插件信息
+    const char* (*get_plugin_name)(void);
+    const char* (*get_plugin_version)(void);
+    
+    // 初始化
+    int32_t (*init)(const char* config);
+    void (*destroy)(void);
+    
+    // 增量检测
+    int32_t (*detect_incremental_blocks)(const char* database, 
+                                        uint64_t since_timestamp,
+                                        SIncrementalBlock** blocks,
+                                        uint32_t* block_count);
+    
+    // 数据导出
+    int32_t (*export_blocks)(const SIncrementalBlock* blocks,
+                             uint32_t block_count,

+    
+    // 数据恢复
+    int32_t (*restore_blocks)(const char* backup_path,
+                              const char* target_database);
+} SBackupPluginInterface;
+```
+
+#### 配置文件格式
+
+```json
+{
+    "plugin": {
+        "name": "incremental_bitmap",
+        "version": "1.0.0",
+        "library_path": "/usr/local/taos/plugins/backup/libincremental_bitmap_plugin.so"
+    },
+    "bitmap_engine": {
+        "type": "roaring",
+        "memory_limit_mb": 1024,
+        "persistence_path": "/var/lib/taos/bitmap_cache"
+    },
+    "event_interceptor": {
+        "enable": true,
+        "buffer_size": 10000,
+        "callback_threads": 4

+        "retry_count": 3,
+        "retry_interval_ms": 1000
+    }
+}
+```
+
+#### 与TDengine的集成点
+
+```c
+// 1. 存储引擎事件监听
+// 通过storage_engine_interface监听块变更事件
+SStorageEngineInterface* interface = get_storage_engine_interface("tdengine");
+interface->install_interception();
+
+// 2. WAL文件监控
+// 监控WAL文件变化，获取增量信息
+int32_t monitor_wal_changes(const char* wal_path, 
+                           WALChangeCallback callback);
+
+// 3. 数据块访问
+// 通过TDengine API访问数据块
+int32_t read_data_block(uint64_t block_id, 
+                        void** data, 
+                        uint32_t* size);
+```

+
+### 环境变量
+
+#### 构建环境变量
+```bash
+# 编译器选择
+export CC=gcc-9
+export CXX=g++-9
+
+# 构建并行度
+export CMAKE_BUILD_PARALLEL_LEVEL=4
+
+# 安装路径
+export CMAKE_INSTALL_PREFIX=/opt/tdengine
+
+# 测试环境
+export CTEST_PARALLEL_LEVEL=4
+export CTEST_OUTPUT_ON_FAILURE=1
+```
+
+#### 运行时环境变量
+```bash
+# 插件路径
+export TDENGINE_PLUGIN_PATH=/usr/local/lib/tdengine/plugins
+
+# 日志级别
+export TDENGINE_LOG_LEVEL=INFO
+
+# 配置文件路径
+export TDENGINE_CONFIG_PATH=/etc/tdengine
+
+# 临时目录
+export TDENGINE_TEMP_PATH=/tmp/tdengine
+
+# TDengine连接配置
+export TD_CONNECT_IP=localhost
+export TD_CONNECT_PORT=6030
+export TD_USERNAME=root
+export TD_PASSWORD=taosdata
+export TD_DATABASE=test
+
+# TMQ配置
+export TD_TOPIC_NAME=test_topic
+export TD_GROUP_ID=test_group
+
+# TMQ超时配置（可选）
+export TMQ_KEY_CONNECT_TIMEOUT=connect.timeout
+export TMQ_KEY_REQUEST_TIMEOUT=request.timeout.ms
+
+# 并发线程覆盖（可选）
+# 若未设置，则默认采用自适应: callback_threads = min(2×在线CPU核数, 64)
+export IB_CALLBACK_THREADS=32
+```
+
+#### TMQ兼容性配置
+
+插件支持TDengine 3.2/3.3系列，通过"多键名回退 + 环境变量覆盖"实现TMQ配置键名的版本兼容。
+
+**键名回退策略**:
+- **连接超时（connect timeout）**
+  - 尝试顺序：`connect.timeout` → `td.connect.timeout` → `connection.timeout`
+  - 可用环境变量：`TMQ_KEY_CONNECT_TIMEOUT`
+- **请求超时（request timeout）**
+  - 尝试顺序：`request.timeout.ms` → `td.request.timeout` → `request.timeout`
+  - 可用环境变量：`TMQ_KEY_REQUEST_TIMEOUT`
+- **数据库名（database）**
+  - 尝试顺序：`td.connect.database` → `td.connect.db`（失败则跳过，不致命）
+
+**版本支持矩阵**:
+- **3.3.x（社区/企业）**：推荐键`td.connect.*`前缀优先，`request.timeout.ms`支持度依版本而异
+- **3.2.x（社区/企业）**：推荐键`connect.timeout` / `request.timeout.ms`，部分`td.connect.*`可能不可用
+
+**最佳实践**:
+- 首次联调：开启`REAL_TDENGINE=1`，观察启动日志中TMQ键名是否生效
+- 如出现警告：使用`TMQ_KEY_*`或`TD_*`环境变量覆盖
+- CI中：固定一套环境变量，保证结果稳定
+
+## 基本使用
+
+### 1. 初始化位图引擎
+
+```c
+#include "bitmap_engine.h"
+#include "event_interceptor.h"
+#include "backup_coordinator.h"
+
+int main() {
+    // 初始化位图引擎
+    SBitmapEngine* engine = bitmap_engine_init();
+    if (!engine) {
+        fprintf(stderr, "Failed to initialize bitmap engine\n");
+        return -1;
+    }
+    
+    // 配置事件拦截器
+    SEventInterceptorConfig event_config = {
+        .enable_interception = true,
+        .event_buffer_size = 10000,
+        .callback_threads = 4, // 示例值；实际运行时默认采用自适应或由 IB_CALLBACK_THREADS 覆盖
+        .callback = NULL,
+        .callback_user_data = NULL
+    };
+    
+    SEventInterceptor* interceptor = event_interceptor_init(&event_config, engine);
+    if (!interceptor) {
+        fprintf(stderr, "Failed to initialize event interceptor\n");
+        bitmap_engine_destroy(engine);
+        return -1;
+    }
+    
+    // 启动事件处理
+    if (event_interceptor_start(interceptor) != 0) {
+        fprintf(stderr, "Failed to start event interceptor\n");
+        event_interceptor_destroy(interceptor);
+        bitmap_engine_destroy(engine);
+        return -1;
+    }
+    
+    // 使用位图引擎进行业务操作
+    // ...
+    
+    // 清理资源
+    event_interceptor_stop(interceptor);
+    event_interceptor_destroy(interceptor);
+    bitmap_engine_destroy(engine);
+    
+    return 0;
+}
+```
+
+### 2. 标记块状态
+
+```c
+// 标记块为脏状态
+int result = bitmap_engine_mark_dirty(engine, block_id, wal_offset, timestamp);
+if (result != 0) {
+    fprintf(stderr, "Failed to mark block as dirty\n");
+}
+
+// 标记块为新增状态
+result = bitmap_engine_mark_new(engine, block_id, wal_offset, timestamp);
+
+// 标记块为删除状态
+result = bitmap_engine_mark_deleted(engine, block_id, wal_offset, timestamp);
+
+// 清除块状态
+result = bitmap_engine_clear_block(engine, block_id);
+```
+
+### 3. 查询块状态
+
+```c
+// 获取块当前状态
+EBlockState state;
+int result = bitmap_engine_get_block_state(engine, block_id, &state);
+if (result == 0) {
+    switch (state) {
+        case BLOCK_STATE_CLEAN:
+            printf("Block is clean\n");
+            break;
+        case BLOCK_STATE_DIRTY:
+            printf("Block is dirty\n");
+            break;
+        case BLOCK_STATE_NEW:
+            printf("Block is new\n");
+            break;
+        case BLOCK_STATE_DELETED:
+            printf("Block is deleted\n");
+            break;
+    }
+} else {
+    printf("Block not found\n");
+}
+```
+
+## 高级功能
+
+### 1. 时间范围查询
+
+```c
+// 获取指定时间范围内的脏块
+int64_t start_time = 1640995200000000000LL; // 2022-01-01 00:00:00
+int64_t end_time = 1641081600000000000LL;   // 2022-01-02 00:00:00
+uint64_t block_ids[1000];
+uint32_t max_count = 1000;
+
+uint32_t count = bitmap_engine_get_dirty_blocks_by_time(
+    engine, start_time, end_time, block_ids, max_count);
+
+printf("Found %u dirty blocks in time range\n", count);
+for (uint32_t i = 0; i < count; i++) {
+    printf("Block ID: %lu\n", block_ids[i]);
+}
+```
+
+### 2. WAL偏移量查询
+
+```c
+// 获取指定WAL偏移量范围内的脏块
+uint64_t start_offset = 0;
+uint64_t end_offset = 1000000;
+uint64_t block_ids[1000];
+uint32_t max_count = 1000;
+
+uint32_t count = bitmap_engine_get_dirty_blocks_by_wal(
+    engine, start_offset, end_offset, block_ids, max_count);
+
+printf("Found %u dirty blocks in WAL range\n", count);
+```
+
+### 3. 备份协调器使用
+
+```c
+// 初始化备份协调器
+SBackupConfig backup_config = {
+    .batch_size = 1000,
+    .max_retries = 3,
+    .retry_interval_ms = 1000,
+    .timeout_ms = 30000,
+    .enable_compression = true,
+    .enable_encryption = false,
+    .backup_path = "/backup",
+    .temp_path = "/tmp"
+};
+
+SBackupCoordinator* coordinator = backup_coordinator_init(engine, &backup_config);
+if (!coordinator) {
+    fprintf(stderr, "Failed to initialize backup coordinator\n");
+    return -1;
+}
+
+// 启动备份协调器
+if (backup_coordinator_start(coordinator) != 0) {
+    fprintf(stderr, "Failed to start backup coordinator\n");
+    backup_coordinator_destroy(coordinator);
+    return -1;
+}
+
+// 获取增量块
+SIncrementalBlock blocks[1000];
+uint32_t count = backup_coordinator_get_incremental_blocks(
+    coordinator, start_wal, end_wal, blocks, 1000);
+
+// 估算备份大小
+uint64_t size = backup_coordinator_estimate_backup_size(
+    coordinator, start_wal, end_wal);
+
+printf("Estimated backup size: %lu bytes\n", size);
+
+// 获取统计信息
+SBackupStats stats;
+backup_coordinator_get_stats(coordinator, &stats);
+printf("Total blocks: %lu, Processed: %lu, Failed: %lu\n",
+       stats.total_blocks, stats.processed_blocks, stats.failed_blocks);
+
+// 清理资源
+backup_coordinator_stop(coordinator);
+backup_coordinator_destroy(coordinator);
+```
+

+将位图插件作为独立的增量备份工具，与taosdump配合使用：
+
+```bash
+# 1. 使用位图插件进行增量检测
+./incremental_bitmap_tool --config bitmap_config.json --output incremental_blocks.json
+
+# 2. 使用taosdump进行数据导出
+taosdump -h localhost -P 6030 -D dbname -o /backup/full/
+
+# 3. 使用位图插件进行增量数据导出
+./incremental_bitmap_tool --export --blocks incremental_blocks.json --output /backup/incremental/
+```
+
+**优势：**
+- 无需修改TDengine核心代码
+- 可以独立开发和维护
+- 支持多种备份策略
+
+#### 方案二：扩展taosdump
+
+在taosdump中添加增量备份功能：

+# 新增的增量备份命令
+taosdump --incremental --bitmap-plugin /path/to/libincremental_bitmap_plugin.so \
+         -h localhost -P 6030 -D dbname -o /backup/incremental/
+```
+
+**优势：**
+- 统一的备份工具
+- 用户使用简单
+
+#### 方案三：创建新的备份工具
+
+开发专门的增量备份工具：
+
+```bash

+    // ...
+};
+
+// 配置合适的批处理大小
+SBackupConfig backup_config = {
+    .batch_size = 5000,          // 根据网络和磁盘性能调整
+    .timeout_ms = 60000,         // 根据数据量调整超时时间
+    // ...
+};
+```
+
+### 2. 并发优化
+
+```c
+// 使用多线程处理事件
+SEventInterceptorConfig config = {
+    .callback_threads = 4,       // 示例；推荐：不指定时采用自适应（min(2×核数, 64)）
+    // ...
+};
+
+// 使用异步处理
+if (event_interceptor_start(interceptor) != 0) {
+    // 处理启动失败
+}
+```
+
+### 3. 存储优化
+
+```c
+// 启用压缩
+SBackupConfig backup_config = {
+    .enable_compression = true,
+    .enable_encryption = false,  // 根据安全需求决定
+    // ...
+};

+// 获取位图引擎统计
+uint64_t total_blocks, dirty_count, new_count, deleted_count;
+bitmap_engine_get_stats(engine, &total_blocks, &dirty_count, &new_count, &deleted_count);
+printf("Stats: total=%lu, dirty=%lu, new=%lu, deleted=%lu\n",
+       total_blocks, dirty_count, new_count, deleted_count);
+
+// 获取事件拦截器统计
+uint64_t events_processed, events_dropped;
+event_interceptor_get_stats(interceptor, &events_processed, &events_dropped);
+printf("Events: processed=%lu, dropped=%lu\n", events_processed, events_dropped);
+```
+
+#### 使用可观测性指标
+```c
+#include "observability.h"
+
+// 更新指标
+update_observability_metrics();
+
+// 打印人类可读格式
+print_observability_metrics();
+
+// 生成JSON格式
+char json_buffer[4096];
+if (format_observability_metrics_json(json_buffer, sizeof(json_buffer)) == 0) {
+    printf("JSON Metrics:\n%s\n", json_buffer);
+}
+```
+
+### 3. 可观测性监控

+**基于指标的调优**
+- **事件处理速率低**: 增加回调线程数，优化事件处理逻辑
+- **内存使用过高**: 调整位图引擎内存限制，启用内存压缩
+- **队列使用率高**: 增加环形队列容量，优化事件处理速度
+- **重试次数过多**: 检查网络连接，优化重试策略
+
+**配置参数调优**
+```c
+// 事件拦截器配置优化
+SEventInterceptorConfig config = {
+    .enable_interception = true,
+    .event_buffer_size = 50000,  // 根据事件产生速率调整
+    .callback_threads = 8,       // 示例；可通过 IB_CALLBACK_THREADS 显式覆盖
+    .callback = NULL,
+    .callback_user_data = NULL
+};
+
+// 位图引擎配置优化
+SBitmapEngineConfig bitmap_config = {
+    .max_memory_mb = 2048,       // 根据可用内存调整
+    .persistence_enabled = true, // 启用持久化减少内存使用
+    .persistence_path = "/tmp/bitmap_cache"
+};
+```
+
+## 最佳实践
+
+### 1. 配置建议
+
+```c
+// 生产环境配置
+SEventInterceptorConfig event_config = {
+    .enable_interception = true,
+    .event_buffer_size = 100000,     // 大缓冲区
+    .callback_threads = 8,           // 示例；默认采用自适应或由 IB_CALLBACK_THREADS 覆盖
+    .callback = NULL,
+    .callback_user_data = NULL
+};
+
+SBackupConfig backup_config = {
+    .batch_size = 10000,             // 大批处理
+    .max_retries = 5,                // 多重试
+    .retry_interval_ms = 2000,       // 长间隔
+    .timeout_ms = 120000,            // 长超时
+    .enable_compression = true,      // 启用压缩
+    .enable_encryption = true,       // 启用加密
+    .backup_path = "/secure/backup",
+    .temp_path = "/tmp"
+};
+```
+
+### 2. 错误处理
+
+```c
+// 完整的错误处理示例
+int perform_backup() {
+    SBitmapEngine* engine = NULL;
+    SEventInterceptor* interceptor = NULL;
+    SBackupCoordinator* coordinator = NULL;
+    
+    // 初始化位图引擎
+    engine = bitmap_engine_init();
+    if (!engine) {
+        fprintf(stderr, "Failed to initialize bitmap engine\n");
+        goto cleanup;
+    }
+    
+    // 初始化事件拦截器
+    SEventInterceptorConfig event_config = { /* ... */ };
+    interceptor = event_interceptor_init(&event_config, engine);
+    if (!interceptor) {
+        fprintf(stderr, "Failed to initialize event interceptor\n");
+        goto cleanup;
+    }
+    
+    // 启动事件拦截器
+    if (event_interceptor_start(interceptor) != 0) {
+        fprintf(stderr, "Failed to start event interceptor\n");
+        goto cleanup;
+    }
+    
+    // 初始化备份协调器
+    SBackupConfig backup_config = { /* ... */ };
+    coordinator = backup_coordinator_init(engine, &backup_config);
+    if (!coordinator) {
+        fprintf(stderr, "Failed to initialize backup coordinator\n");
+        goto cleanup;
+    }
+    
+    // 执行备份逻辑
+    // ...
+    
+    return 0;
+
+cleanup:
+    if (coordinator) {
+        backup_coordinator_destroy(coordinator);
+    }
+    if (interceptor) {
+        event_interceptor_destroy(interceptor);
+    }
+    if (engine) {
+        bitmap_engine_destroy(engine);
+    }
+    return -1;
+}
+```
+
+### 3. 资源管理
+
+```c
+// 使用RAII模式管理资源
+typedef struct {
+    SBitmapEngine* engine;
+    SEventInterceptor* interceptor;
+    SBackupCoordinator* coordinator;
+} BackupContext;
+
+BackupContext* create_backup_context() {
+    BackupContext* ctx = malloc(sizeof(BackupContext));
+    if (!ctx) return NULL;
+    
+    memset(ctx, 0, sizeof(BackupContext));
+    return ctx;
+}
+
+void destroy_backup_context(BackupContext* ctx) {
+    if (!ctx) return;
+    
+    if (ctx->coordinator) {
+        backup_coordinator_destroy(ctx->coordinator);
+    }
+    if (ctx->interceptor) {
+        event_interceptor_destroy(ctx->interceptor);
+    }
+    if (ctx->engine) {
+        bitmap_engine_destroy(ctx->engine);
+    }
+    
+    free(ctx);
+}
+```
+
+### 4. 性能监控
+
+```c
+// 定期监控性能指标
+void monitor_performance(BackupContext* ctx) {
+    // 获取位图引擎统计
+    uint64_t total_blocks, dirty_count, new_count, deleted_count;
