亚马逊网络服务DynamoDB :解组BatchGetItem响应

import boto3

dynamodb = boto3.client('dynamodb')

response = dynamodb.batch_get_item(
    RequestItems={
        'YourTableName': {
            'Keys': [
                {'PrimaryKey': 'value1'},
                {'PrimaryKey': 'value2'}
            ]
        }
    }
)

# 处理响应
items = response.get('Responses', {}).get('YourTableName', [])
unprocessed_keys = response.get('UnprocessedKeys', {}).get('YourTableName', [])

if unprocessed_keys:
    print("部分键未找到:", unprocessed_keys)
else:
    print("所有请求的项目都已找到:", items)

# 增加读取容量单位
dynamodb.update_table(
    TableName='YourTableName',
    ProvisionedThroughput={
        'ReadCapacityUnits': 100,
        'WriteCapacityUnits': 50
    }
)
