Where is Fuseki server storing triple data?

Question

I have installed Jena Fuseki on my computer and I after I create dataset I see in my file system that it appears under fuseki\run\configuration folder, but I cannot find the triples that I upload to this dataset.

I want to process datasets with Python and then store them in jena fuseki, so I don't want to use the web app GUI that jena provides for uploading new triples. My question is how to accomplish this and where does Jena store uploaded triples?

If you created a persistent database via the UI, it's in run/db/. If the database is in a configuration file on server startup, it is whereever the config puts it. Things are not stores as RDF file - they are triplestore database (TDB by default). — AndyS, May 02 '19 at 21:52

If you don't want to use the web app UI, Fuseki offers a number of ways to get data into it:

The soh set of command line tools, in particular s-put. These commands can be called from Python.
The SPARQL Graph Store Protocol. This is a simple HTTP protocol.
SPARQL Update over the SPARQL Protocol. There are Python client libraries for the SPARQL Protocol, see for example here and here.

It sounds like you are trying to upload data by directly accessing Fuseki's internal file storage. That's probably not a good idea. Access should go through the officially supported interfaces.
