That would be very helpful.
"documentation" is a task in the next few days. It's the block on
sending any messages to users@ etc about it.
The raw material is in git:
https://github.com/apache/jena/blob/master/jena-db/use-fuseki-tdb2.md
https://github.com/apache/jena/blob/master/jena-db/use-tdb2-cmds.md
The commands are in the binary distribution "apache-jena" download but
there are no script wrappers (easy to copy and fix though).
Either run from development or
java -cp 'DIR/lib/*' tdb2.tdbloader ... args ...

From TDB2 and Fuseki's point of view, that's no longer true.
You can (should be able to) load any amount.
The fuseki-basic server also has TDB2 in it so if you are doing
everything script-driven, you can run that "--conf config-tdb2.ttl"
There is no progress indicator in the server log so you may wish to set
set some kind of verbose option in the sender.

Uploading large files:
The UI does this all quite well.
What's the magic for a command line/scripted process?
It needs a tool that does not buffer or inspect the file or otherwise
try to be helpful.
Anyone know of good tools for this?
I haven't managed to work out which set of "curl" arguments do this
without buffering the file (--data* seem to buffer the file; -F is a
form upload, not pure POST).
This seems to work:
wget --post-file=/home/afs/Datasets/BSBM/bsbm-200m.nt --header
'Content-type: application/n-triples' http://localhost:3030/data
200M BSBM (49Gbytes) loaded at 42K triples/s.
The content length in the fuskei log is reported wrongly (1002691465 ...
int/long error) but the triple count is right.
It does ruins the interactive performance of the machine!
s-post crashes immediately if given a large files - don't know why.

Excellent!
I have a couple of Fuseki installations where I could test drive this.
I'd just need to know how to do the configuration, and also a tool like
tdbloader for offline loading since some of my data files are too big to
be loaded via the Graph Store API.
No hurry though.

It's in the build joined in at apache-jena-libs.
It is in Fuseki2 server jar, but not the UI - a user needs to use a
configuration file. That also works in fuseki-basic.
Documentation to follow.
