Hi, I am trying to upload a 560 GB file to s3 bucket and it's failing with below error.

[Exception] An error occurred (InvalidArgument) when calling the UploadPart operation: Part number must be an integer between 1 and 10000, inclusive

AWS (as many others s3-like storages) recommends not to exceed 10,000 parts in multipart upload - https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html
