要将MySQL Aurora复制到SQL Server，您可以使用AWS Database Migration Service（AWS DMS）来完成此任务。下面是一个示例代码，演示如何通过AWS CLI创建一个CDC（Change Data Capture）任务：

1. 准备工作：

   • 确保您具有适当的AWS CLI安装和配置。
   • 确保您具有AWS DMS的访问权限。

2. 创建JSON文件，指定CDC任务配置。以下是一个示例配置文件：

{
  "MigrationType": "cdc",
  "SourceEndpoint": {
    "EndpointIdentifier": "mysql-source-endpoint",
    "EndpointType": "source",
    "EngineName": "aurora",
    "Username": "your-aurora-username",
    "Password": "your-aurora-password",
    "ServerName": "your-aurora-server",
    "Port": 3306
  },
  "TargetEndpoint": {
    "EndpointIdentifier": "sqlserver-target-endpoint",
    "EndpointType": "target",
    "EngineName": "sqlserver",
    "Username": "your-sqlserver-username",
    "Password": "your-sqlserver-password",
    "ServerName": "your-sqlserver-server",
    "Port": 1433
  },
  "ReplicationTaskIdentifier": "mysql-aurora-to-sqlserver-cdc-task",
  "MigrationTaskSettings": {
    "TargetMetadata": {
      "TargetSchema": "your-sqlserver-schema"
    },
    "StreamBufferCount": 8,
    "StreamBufferSeconds": 600,
    "ChangeProcessingTuning": {
      "BatchApplyEnabled": true,
      "BatchApplyPreserveTransaction": true,
      "BatchApplyTimeoutMin": 10,
      "BatchApplyTimeoutMax": 60
    }
  }
}

请确保将上述配置文件中的"your-aurora-username"、"your-aurora-password"、"your-aurora-server"、"your-sqlserver-username"、"your-sqlserver-password"、"your-sqlserver-server"和"your-sqlserver-schema"替换为您自己的实际值。

3. 执行以下命令创建CDC任务：

aws dms create-replication-task --replication-task-settings file://cdc-task-config.json

确保将"cdc-task-config.json"替换为您创建的JSON配置文件的路径。

以上命令将使用AWS DMS创建一个CDC复制任务，从MySQL Aurora源复制到SQL Server目标。这将自动将更改从Aurora复制到SQL Server。
