DMS 仅向现有数据迁移添加列

如何解决DMS 仅向现有数据迁移添加列

我将 DMS 用于迁移现有数据并将正在进行的更改（初始加载 + CDC）复制到红移的任务。该任务首先创建初始加载，然后继续添加 CDC 文件。 我只需要为初始加载部分创建一个额外的列，并保留来自 DMS 的 CDC 数据。为此，我使用了自定义规则，不幸的是，这些规则还将该列添加到 CDC 部分。是否可以只将其添加到初始加载中？

    {
    "rules": [
        {
            "rule-type": "selection","rule-id": "1","rule-name": "1","object-locator": {
                "schema-name": "public","table-name": "%"
            },"rule-action": "include"
        },{
            "rule-type": "transformation","rule-id": "2","rule-name": "2","rule-action": "add-column","rule-target": "column","value": "op","expression": "'i_load'","data-type": {
                "type": "string","length": 8
            }
        }
    ]
}
