Boto3: S3: Should put_object automatically split files larger than 5GB?

[Juboo]

S3 doesn't allow you to PUT files more than 5gb at a time. However, boto3 will allow me to run something like :

import boto3
s3 = boto3.resource('s3')
data = open('/6gbfile', 'rb')
s3.Bucket('myTestBucket').put_object(Key='6gbfile', Body=data)

After a minute or so it throws:
botocore.exceptions.ClientError: An error occurred (EntityTooLarge) when calling the PutObject operation: Your proposed upload exceeds the maximum allowed size

I must use split in order to upload my large files! Should boto3 handle this for the user?

The put_object method maps directly to the PutObject API request in S3. boto3 offers higher level abstractions that you can use that will automatically manage the multipart uploads for you. Docs here: http://boto3.readthedocs.io/en/latest/guide/s3.html#uploads. You can use either the upload_file or the upload_fileobj method. Let me know if you have any more questions.

Guys, so according to you then the multipart upload is driven by boto3 automatically? it's not required an upload ID to gather the parts upload of the file in AWS S3? @jamesls

I was following the documentation and then seems like the multipart in Python API is only used for glacier? @kopertop
thanks
