Fun Trivia note: when you do a multipart upload, the S3 hash of the object is not the same as it is when you do a single part upload. I had a file with the same contents but a different hash when I used Python than when it was transferred with the CLI or CloudBerry. The quick and dirty way to fix the hash is to copy the file to itself with Boto3.
Just from a cursory glance, I couldn’t find any samples of how to do a multipart upload with retries in Python with Boto3.
This is an example of how to do multipart uploads though.
