如何使用Pyhon SDK中的DynamoDb持久性适配器

pip install boto3

import boto3

# 创建DynamoDB客户端
dynamodb = boto3.client('dynamodb')

# 创建表
response = dynamodb.create_table(
    TableName='my-table',
    KeySchema=[
        {
            'AttributeName': 'id',
            'KeyType': 'HASH'
        }
    ],
    AttributeDefinitions=[
        {
            'AttributeName': 'id',
            'AttributeType': 'N'
        }
    ],
    ProvisionedThroughput={
        'ReadCapacityUnits': 5,
        'WriteCapacityUnits': 5
    }
)

# 插入数据
response = dynamodb.put_item(
    TableName='my-table',
    Item={
        'id': {'N': '1'},
        'name': {'S': 'John'}
    }
)

# 查询数据
response = dynamodb.get_item(
    TableName='my-table',
    Key={
        'id': {'N': '1'}
    }
)

# 更新数据
response = dynamodb.update_item(
    TableName='my-table',
    Key={
        'id': {'N': '1'}
    },
    UpdateExpression='SET name = :val',
    ExpressionAttributeValues={
        ':val': {'S': 'Jane'}
    }
)

# 删除数据
response = dynamodb.delete_item(
    TableName='my-table',
    Key={
        'id': {'N': '1'}
    }
)
