使用aws cdk时dynamodb的TableProps是多少

Question

我正在使用aws cdk for dynamodb，想要添加一个dynamodb表，我已经得到了这段代码，什么是dynamodb的TableProps？我还以为是字符串类型的表名呢，但是好像错了，有没有人能帮我一下？

https://docs.aws.amazon.com/cdk/api/latest/typescript/api/aws-dynamodb/tableprops.html#aws_dynamodb_TableProps_tableName

import core = require('@aws-cdk/core');
import dynamodb = require('@aws-cdk/aws-dynamodb')

export class HelloCdkStack extends core.Stack {
  constructor(scope: core.App, id: string, props?: core.StackProps) {
    super(scope, id, props);

    new dynamodb.Table(this, 'MyFirstTable', {
        tableName: 'myTable'
      });
  }
}

这就是错误

lib/dynamodb.ts:8:46 - error TS2345: Argument of type '{ tableName: string; }' is not assignable to parameter of type 'TableProps'.
  Property 'partitionKey' is missing in type '{ tableName: string; }' but required in type 'TableProps'.

 8     new dynamodb.Table(this, 'MyFirstTable', {
                                                ~
 9         tableName: 'myTable'
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10       });
   ~~~~~~~

  node_modules/@aws-cdk/aws-dynamodb/lib/table.d.ts:19:14
    19     readonly partitionKey: Attribute;
                    ~~~~~~~~~~~~
    'partitionKey' is declared here.

Answer 1

试一试

import { AttributeType } from '@aws-cdk/aws-dynamodb';

    new dynamodb.Table(this, 'MyFirstTable', {
      tableName: "myTable",
      partitionKey: {
            name: "MyPartitionkey,
            type: AttributeType.STRING
          }
    });

Answer 2

TableProps扩展了TableOptions，"partionKey“是使用dynamodb.Table创建表所必需的属性。我认为aws CDK文档可以更清楚地说明"TableProps“如何使用"TableOptions”。

export interface TableProps extends TableOptions

在"partionKey“部分的TableOptions下，它说：

readonly partitionKey: Attribute;

不带"?“在"partionKey“和":”之间标记，表示此属性是必需的。
