machine-to-machine transfer of files from landing zones

[gravesee]

I am looking at using WsFileIO/ReadFileData to download files from a landing zone. The response data comes back as base64 encoded data. Is there a documented means of transferring raw bytes? I have also looked at using the FileSpray/DownloadFile endpoint. With WsFileIO I can use the offset and data size parameters to queue up multiple parallel requests which should be faster, however the decoding overhead from base64 is hurting performance. My ultimate goal is to transfer data from a landingzone to Azure without needed to stand up special infrastructure (lenticmanager) OR login in to the landing zone directly (ssh + AzCopy).
