-## Cluster Type Explanation - -### Impact of Cluster Type on Performance - -MongoDB Connector automatically optimizes connection parameters and read/write strategies based on different cluster types: - -#### 1. **Standalone (Single Instance)** -- **Read/Write Preference**: `PrimaryPreferred` - Prefer reading from primary node, fallback to other nodes when primary is unavailable -- **Write Concern**: Default - Write to primary node is sufficient -- **Use Cases**: Development environments, small applications, single deployments - -#### 2. **Replica Set** -- **Read/Write Preference**: `SecondaryPreferred` - Prefer reading from secondary nodes to distribute primary node load -- **Write Concern**: `{W: "majority", J: true}` - Write to majority of nodes and wait for journal persistence -- **Retry Writes**: Enabled - Automatically retry on network failures -- **Use Cases**: Production environments, high availability requirements, read/write separation - -#### 3. **Sharded Cluster** -- **Read/Write Preference**: `Nearest` - Read from nearest node to reduce network latency -- **Write Concern**: `{W: "majority", J: true}` - Write to majority of shards and wait for journal persistence -- **Retry Writes**: Enabled - Automatically retry on inter-shard network failures -- **Use Cases**: Large data volumes, high concurrency, geographically distributed deployments - -### Automatic Optimization Features - -- **Connection Pool Management**: Automatically adjust connection pool size and timeout settings based on cluster type -- **Read/Write Separation**: Automatically enable read/write separation optimization for replica sets and sharded clusters -- **Fault Recovery**: Automatically detect node failures and switch to available nodes -- **Performance Monitoring**: Provide corresponding performance metrics based on cluster type - -## Authentication Database Explanation - -### Why Authentication Database is Needed - -In MongoDB, user authentication information is typically stored in the `admin` database rather than in business databases. When connecting to a MongoDB instance that requires authentication, the correct authentication database needs to be specified. - -### Authentication Database Configuration Methods - -1. **Via Connection String**: - ``` - mongodb://username:password@localhost:27017/database?authSource=admin - ``` - -2. **Via Configuration Field** (Recommended): - ```json - { - "connection_uri": "mongodb://username:password@localhost:27017/database", - "auth_database": "admin" - } - ``` - -### Common Authentication Scenarios - -- **Users exist in admin database**: Set `"auth_database": "admin"` -- **Users exist in target database**: Set `"auth_database": "database_name"` or leave empty -- **No authentication**: Connection string doesn't contain username/password, `auth_database` field is invalid - -## Best Practices - -### 1. Connection Configuration -- Use environment variables for sensitive information (username, password) -- Configure appropriate connection pool size for production environments -- Set reasonable timeout values -- Correctly configure authentication database -- Select correct cluster type based on actual deployment - -### 2. Collections Configuration -- Use filters to reduce unnecessary data transmission -- Create indexes for timestamp fields to improve incremental synchronization performance -- Set field mappings reasonably to avoid retrieving useless data - -### 3. Performance Optimization -- Adjust page size and batch size based on data volume -- Enable projection pushdown to reduce network transmission -- Use index hints to optimize query performance - -### 4. Incremental Synchronization -- Ensure timestamp fields have appropriate indexes -- Regularly clean up old synchronization state files -- Monitor synchronization performance and adjust configuration parameters - -## Troubleshooting - -### Common Issues - -#### 1. Connection Failure -- Check connection string format -- Verify network connectivity and firewall settings -- Confirm MongoDB service is running -- Check authentication database configuration is correct -- Confirm cluster type configuration matches actual deployment - -#### 2. Poor Synchronization Performance -- Check if appropriate indexes exist -- Adjust page size and batch size -- Enable projection pushdown optimization - -#### 3. Incremental Synchronization Not Working -- Confirm `last_modified_field` is set correctly -- Check timestamp field data type -- Verify incremental synchronization strategy configuration - -#### 4. High Memory Usage -- Reduce page size and batch size -- Enable pagination processing -- Check field mapping configuration - -#### 5. Cluster Performance Issues -- Check if cluster type configuration is correct -- Verify read/write preference settings are suitable for business requirements -- Confirm connection pool size is appropriate for cluster scale -- Check network latency and bandwidth limitations - -## Monitoring and Logging - -### Log Levels -- `DEBUG`: Detailed debug information -- `INFO`: General operation information -- `WARN`: Warning information -- `ERROR`: Error information - -### Key Metrics -- Number of synchronized documents -- Processing time -- Memory usage -- Error rate - -### Monitoring Recommendations -- Regularly check synchronization status -- Monitor system resource usage -- Set alert thresholds -- Record performance metrics \ No newline at end of file diff --git a/config/setup/zh-CN/mongodb.tpl b/config/setup/zh-CN/mongodb.tpl deleted file mode 100644 index 32d76d68..00000000 --- a/config/setup/zh-CN/mongodb.tpl +++ /dev/null @@ -1,391 +0,0 @@ -# MongoDB 连接器配置 -

-## 集群类型说明 - -### 集群类型对性能的影响 - -MongoDB 连接器根据不同的集群类型自动优化连接参数和读写策略： - -#### 1. **Standalone (单机实例)** -- **读写偏好**: `PrimaryPreferred` - 优先从主节点读取，主节点不可用时从其他节点读取 -- **写入关注点**: 默认 - 写入到主节点即可 -- **适用场景**: 开发环境、小型应用、单机部署 - -#### 2. **Replica Set (复制集)** -- **读写偏好**: `SecondaryPreferred` - 优先从从节点读取，分散主节点负载 -- **写入关注点**: `{W: "majority", J: true}` - 写入到多数节点并等待日志持久化 -- **重试写入**: 启用 - 网络故障时自动重试 -- **适用场景**: 生产环境、高可用性要求、读写分离 - -#### 3. **Sharded Cluster (分片集群)** -- **读写偏好**: `Nearest` - 从最近的节点读取，减少网络延迟 -- **写入关注点**: `{W: "majority", J: true}` - 写入到多数分片并等待日志持久化 -- **重试写入**: 启用 - 分片间网络故障时自动重试 -- **适用场景**: 大数据量、高并发、地理分布式部署 - -### 自动优化特性 - -- **连接池管理**: 根据集群类型自动调整连接池大小和超时设置 -- **读写分离**: 复制集和分片集群自动启用读写分离优化 -- **故障恢复**: 自动检测节点故障并切换到可用节点 -- **性能监控**: 根据集群类型提供相应的性能指标 - -## 认证数据库说明 - -### 为什么需要认证数据库？ - -在MongoDB中，用户认证信息通常存储在`admin`数据库中，而不是在业务数据库中。当连接到需要认证的MongoDB实例时，需要指定正确的认证数据库。 - -### 认证数据库配置方式 - -1. **通过连接字符串**： - ``` - mongodb://username:password@localhost:27017/database?authSource=admin - ``` - -2. **通过配置字段**（推荐）： - ```json - { - "connection_uri": "mongodb://username:password@localhost:27017/database", - "auth_database": "admin" - } - ``` - -### 常见认证场景 - -- **用户存在于admin数据库**：设置 `"auth_database": "admin"` -- **用户存在于目标数据库**：设置 `"auth_database": "database_name"` 或留空 -- **无认证**：连接字符串中不包含用户名密码，`auth_database` 字段无效 - -## 最佳实践 - -### 1. 连接配置 -- 使用环境变量存储敏感信息（用户名、密码） -- 为生产环境配置适当的连接池大小 -- 设置合理的超时时间 -- 正确配置认证数据库 -- 根据实际部署选择正确的集群类型 - -### 2. 集合配置 -- 使用过滤器减少不必要的数据传输 -- 为时间戳字段创建索引以提高增量同步性能 -- 合理设置字段映射，避免获取无用数据 - -### 3. 性能优化 -- 根据数据量调整页面大小和批处理大小 -- 启用投影下推减少网络传输 -- 使用索引提示优化查询性能 - -### 4. 增量同步 -- 确保时间戳字段有适当的索引 -- 定期清理旧的同步状态文件 -- 监控同步性能，调整配置参数 - -## 故障排除 - -### 常见问题 - -#### 1. 连接失败 -- 检查连接字符串格式 -- 验证网络连接和防火墙设置 -- 确认MongoDB服务正在运行 -- 检查认证数据库配置是否正确 -- 确认集群类型配置与实际部署一致 - -#### 2. 认证失败 -- 确认用户名和密码正确 -- 检查用户是否存在于指定的认证数据库中 -- 验证用户是否有访问目标数据库的权限 -- 检查MongoDB的认证机制（SCRAM-SHA-1, SCRAM-SHA-256等） - -#### 3. 同步性能差 -- 检查是否有适当的索引 -- 调整页面大小和批处理大小 -- 启用投影下推优化 - -#### 4. 增量同步不工作 -- 确认`last_modified_field`设置正确 -- 检查时间戳字段的数据类型 -- 验证增量同步策略配置 - -#### 5. 集群性能问题 -- 检查集群类型配置是否正确 -- 验证读写偏好设置是否适合业务需求 -- 确认连接池大小适合集群规模 -- 检查网络延迟和带宽限制 - -## 总结 - -MongoDB 连接器现在完全支持认证数据库和集群类型配置，提供了灵活且强大的配置选项，可以满足各种数据同步需求。通过合理配置，特别是正确设置认证数据库和集群类型，可以实现高效、可靠的数据同步，同时保持良好的性能表现。 - -### 新增功能亮点 - -1. **集群类型感知**: 自动识别并优化不同集群类型的连接参数 -2. **智能读写分离**: 根据集群类型自动选择最优的读写策略 -3. **故障恢复增强**: 复制集和分片集群的自动故障检测和恢复 -4. **性能自动调优**: 根据集群类型自动调整连接池和超时设置 - -这些改进使得MongoDB 连接器能够更好地适应不同的生产环境，提供更稳定、更高效的数据同步服务。 From fe69e19236a236f47a99240be51d6e752d8d61be Mon Sep 17 00:00:00 2001 From: undertaker86001 Date: Fri, 22 Aug 2025 09:27:30 +0800 Subject: [PATCH 19/31] remove useless files --- plugins/connectors/mongodb/config_test.go | 438 ---------------------- 1 file changed, 438 deletions(-) delete mode 100644 plugins/connectors/mongodb/config_test.go diff --git a/plugins/connectors/mongodb/config_test.go b/plugins/connectors/mongodb/config_test.go deleted file mode 100644 index 41a5c398..00000000 --- a/plugins/connectors/mongodb/config_test.go +++ /dev/null @@ -1,438 +0,0 @@ -package mongodb -
