Question

在Aws lambda函数中，我正在存储图像，而我的图像是我的主键。但是没有案例，我可以将相同的图像存储在不同的功能中。 John也可以是function1和function2的一部分。因此，当我在第二和第二个存储中时，都将其删除。我的表结构是通过

获得的

aws dynamodb describe-table --table-name athlete_collection

结果：

"Table": {
        "TableName": "athlete_collection",
        "TableSizeBytes": 77,
        "CreationDateTime": 1528273139.189,
        "ProvisionedThroughput": {
            "ReadCapacityUnits": 1,
            "NumberOfDecreasesToday": 0,
            "WriteCapacityUnits": 1
        },
        "StreamSpecification": {
            "StreamViewType": "NEW_AND_OLD_IMAGES",
            "StreamEnabled": true
        },
        "TableArn": "arn:aws:dynamodb:us-east-1:969213561829:table/athlete_collection",
        "ItemCount": 1,
        "TableId": "8cc40165-5ac2-4aa2-9db4-f06ffad8639c",
        "LatestStreamLabel": "2018-06-13T07:22:00.651",
        "AttributeDefinitions": [
            {
                "AttributeName": "RekognitionId",
                "AttributeType": "S"
            }
        ],
        "KeySchema": [
            {
                "AttributeName": "RekognitionId",
                "KeyType": "HASH"
            }
        ],
        "LatestStreamArn": "arn:aws:dynamodb:us-east-1:969213561829:table/athlete_collection/stream/2018-06-13T07:22:00.651",
        "TableStatus": "ACTIVE"
    }
}

我是这样查询的

aws dynamodb create-table --table-name athlete_collection \
--attribute-definitions AttributeName=RekognitionId,AttributeType=S \
--key-schema AttributeName=RekognitionId,KeyType=HASH \
--provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1 \
--region eu-west-1

创建Dynamodb复合密钥
