We should enable S3 Transfer Acceleration. This is a setting enabled on specific S3 buckets that enables accelerated uploads (and downloads?) with multi-part transfer. Details here: https://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html
I enabled S3 transfer acceleration on my bucket and set my `nuxeo.s3storage.endpoint` but got `exception_message : To enable accelerate mode, please use AmazonS3ClientBuilder.withAccelerateModeEnabled(true)`.
(Florent Guillaume) "we're not compatible out of the box. That's because of how the AWS SDK is coded. There is a technical reason though: in accelerate mode, the endpoint in request is regionless. We need the client-wide endpoint to fetch the region information and pick the correct signer."
Among other things, it looks like this contribution needs to add the "accelerateMode" config:
Even creating an XML override in Studio and setting the accelerateMode config did not enable this to work.
