使用 Amplify CLI 工具包从多个 GSI 中删除单个 GSI

Question

我想从项目中的 4 个 GSI 中删除单个 GSI。 但 Amplify CLI 工具包仅提供删除所有 GSI 的选项。当我运行

amplify update storage

时，CLI 工具包在流程中询问以下选项：

Do you want to keep existing global secondary indexes created on your table? (Y/n) · no

对此选项选择“否”会立即删除所有 GSI。 （并且在 amplify cli 版本 12.10.3 中没有选择和删除单个 GSI 的选项）

当我对上述选项选择“否”并尝试将更改推送到服务器时，出现以下错误：

🛑 The following resources failed to deploy:
Resource Name: DynamoDBTable (AWS::DynamoDB::Table)
Event Type: update
Reason: Resource handler returned message: "Cannot perform more than one GSI creation or deletion in a single update" (RequestToken: fcd558ca-1d24-4590-d3b1-d5f57c0cc17f, HandlerErrorCode: InvalidRequest)

我试图找到一种方法来仅删除选定的GSI，但我没有找到任何这样的选项。

我设法通过进入

amplify/backend/storage/<dynamodbresourcename>/cli-inputs.json

文件删除单个 GSI，该文件的结构类似于以下内容：

{
  "resourceName": "dbname",
  "tableName": "dbnane",
  "partitionKey": {
    "fieldName": "pk",
    "fieldType": "string"
  },
  "sortKey": {
    "fieldName": "sk",
    "fieldType": "string"
  },
  "gsi": [
    {
      "name": "gs1",
      "partitionKey": {
        "fieldName": "gs1pk",
        "fieldType": "string"
      },
      "sortKey": {
        "fieldName": "gs1sk",
        "fieldType": "string"
      }
    },
    {
      "name": "gs2",
      "partitionKey": {
        "fieldName": "gs2pk",
        "fieldType": "string"
      },
      "sortKey": {
        "fieldName": "gs2sk",
        "fieldType": "string"
      }
    },
    {
      "name": "gs3",
      "partitionKey": {
        "fieldName": "gs3pk",
        "fieldType": "string"
      },
      "sortKey": {
        "fieldName": "gs3sk",
        "fieldType": "string"
      }
    }
  ],
  "triggerFunctions": []
}

然后我简单地从

gsi

数组中删除了我想要删除的 GSI 的条目。例如，如果我想删除

gs3

，我从 gsi 数组中删除了该条目，之后 json 如下所示：

{
  "resourceName": "dbname",
  "tableName": "dbname",
  "partitionKey": {
    "fieldName": "pk",
    "fieldType": "string"
  },
  "sortKey": {
    "fieldName": "sk",
    "fieldType": "string"
  },
  "gsi": [
    {
      "name": "gs1",
      "partitionKey": {
        "fieldName": "gs1pk",
        "fieldType": "string"
      },
      "sortKey": {
        "fieldName": "gs1sk",
        "fieldType": "string"
      }
    },
    {
      "name": "gs2",
      "partitionKey": {
        "fieldName": "gs2pk",
        "fieldType": "string"
      },
      "sortKey": {
        "fieldName": "gs2sk",
        "fieldType": "string"
      }
    }
  ],
  "triggerFunctions": []
}

然后运行命令

amplify push storage

。

我希望这对某人有帮助。
