SQS message_id vs MessageId

[iamtennislover]

I see that message.message_id is different from body['MessageId']? What is the difference between the two?

sqs = boto3.resource('sqs', region_name=region, aws_access_key_id=aws_access_key_id, aws_secret_access_key=aws_secret_access_key)
queue_obj = sqs.Queue(queue_url)
messages = queue_obj.receive_messages(
            AttributeNames=['All'],
            MessageAttributeNames=['All'],
            VisibilityTimeout=15,
            WaitTimeSeconds=20,
            MaxNumberOfMessages=5
)
for message in messages:
    body = json.loads(message.body)
    print(str(message.message_id) == str(body['MessageId'])) # This prints False all the time

I replied back on the Stack Overflow post. Let's keep the conversation there as we are trying to limit open GitHub issues to bugs and feature requests as shown in the boto3 README.

Thanks. I would like know which Id is going to be unique in a queue? I would like to store messages by id as key
