AWS DMS转换

Question

我有一个与我的PC连接的MySQL服务器。在DynamoDB和MySQL数据库中都有一个名为“ purchase”的表。当我尝试从购买表中删除一列（“规则操作”：“删除”）时，整个表都将被删除。表映射如下：

{
"rules": [
    {
        "rule-type": "selection",
        "rule-id": "1",
        "rule-name": "1",
        "object-locator": {
            "schema-name": "mydatabase",
            "table-name": "purchase"
        },
        "rule-action": "include"
    },
    {
        "rule-type": "transformation",
        "rule-id": "2",
        "rule-name": "2",
        "rule-target": "column",
        "object-locator": {
            "schema-name": "mydatabase",
            "table-name": "purchase",
            "column-name": "quantity"
        },
        "rule-action": "remove-column"
    }
