Also interested in answers. I asked Andy a few years ago and I believe he
said it was best done via SPARQL, which went against my intuition that some
fast path shortcuts would help. I guess he meant this:

Looking at

Steven's email is about server performance, not functionality.
I realize I am unsure whether the file: URI is in the client or server side
of the protocol.
UpdateLoad("file:etc/update-data.ttl", "http://example/g2";))
Local.
The reason I care is from a sense that we have now a lot of interoperable
data in RDF, and many SPARQL implementations with different strengths and
weaknesses. Yet it is hard to systematically mix-and-match eg in a Cloud
(docker etc.) environment without a lot of work on data loading. We are 25+
years into RDF now, but hopefully things will continue to get easier!
Use GSP:

You can pump data across the network without additional copying in the
HTTP stack.
(Jena supports HTTP multifile upload - not sure about other systems but
it is not RDF-related - this it is standard HTTP functionality).
