Really interesting going through your code, thanks for sharing. Why did you opt for running the parallelization code in a separate python process (s3op)?

You might want to update section ‚Caution: Overwriting data in S3‘ in the docs since S3 offers strong read after write consistency since dec 2020.

re: separate process - fault-tolerance is a key requirement. There are a myriad of ways how a highly parallelized, network- and data-intensive code can fail, so isolating it in a separate process is a safer approach than trying to try-except everything and hope it works.

Good catch re: the warning about consistency! The docs were written before the change :)
