Thanks for the reply.
The data model is relatively simple, dealing with transactions of goods and user data. I will wait for the next release of Jena. When is it scheduled?

The data pattern also affects load speeds. > > Andy > > On 06/12/2021 13:14, robert.ba...@tiscali.it [2]wrote: > >> Hello, I have to upload 3 billion triples to Jena Fuseki. I tried using the following command with a first dataset (0.ttl.gz 1.ttl.gz => 750 million triples): tdb2_tdbloader.bat --loader = parallel --loc datasetX 0.ttl.gz 1.ttl.gz. Loading took about 8 hours to upload 750 milion. The system has a Core-i7, 16 G ram, SSD hard-disk. Is it possible to optimize loading times? I have seen that there are several types of loaders: tdbloader tdbloader2 (I can also use a linux system) tdb2_tdbloader (with different options) Which of these is the best? Thanks!
