S3 connector's putObject is wrong

[vigoo]

It seems to repeatedly call putObject for each chunk, which just overwrites the same object every time. It should use the multipart upload API: https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpuoverview.html

Is there a workaround for this?

One workaround is to rechunk your ZStream to have 1 underlying chunk.
