Description

Azure Blob Store and S3 support CDNs in front of private containers/buckets, which also work with presigned URLs (S3 docs, cloudfront presigning java, Azure docs). The binary access feature should support these for download URLs via a configuration on the DataStore.

Currently, the S3 datastore has a config for transfer acceleration that if enabled, will make both upload & download URLs use the acceleration option. However, this feature only makes sense for uploads, especially if CDN is an option for downloads.
