Boto3: Is there a way to batch get items using hash range keys from dynamodb?

Question

I see from their documentation you can batch_get_item for single items

http://boto3.readthedocs.io/en/latest/reference/services/dynamodb.html#DynamoDB.Client.batch_get_item

but I'm not quite sure how to get items from tables with hash range keys. Particularly batch getting items with just the hash value, is this possible?

Answer 1

you can follow this code:

dynamodb = boto3.resource('dynamodb')
r = dynamodb.batch_get_item(RequestItems={
            'TABLE_NAME': {
                'Keys': [
                    {
                        'myPrimaryKey': "123",
                        'mySortKey': "65894"
                    },
                    {
                        'myPrimaryKey': "123",
                        'mySortKey': "65004"
                    },
                    {
                        'myPrimaryKey': "123",
                        'mySortKey': "69654"
                    }
                ],
            },
})

print(r["Responses"]["TABLE_NAME"])
print(r["UnprocessedKeys"])
