Concept: High Performance Backend for big files: What is its scope?

Hi there
I’d like to ask about the (future) concept of HPB.

I understand that HPB is advertized in the region of polling and fast inter-machine messaging.
I see that for actual data (file-) transfer there exists a concept called “bulk upload”.
I read somewhere that WebDAV transfer seems to be dicussed as a “fallback option”.

Currently there seem to be issues open around the bulk upload from the client.
I could never saturate my 1G/10G line over a local subnet.

Nevertheless what is the conceptual future target with transfers, bandwidth and the possible saturation of a line for big files?

Is HPB meant to become the superior offloader for big files, if present?
Can someone enlighten me?

Thank you very much
Regards!

How big are the files?

8 to 40+ GB
If you ask for the bulk uploader issue, these are 20k (amount) files totalling 4 GBytes.
