Hi,
Now I'm trying to load 200M triples. With "I don't think it's optimal" I
wanted to say that I don't know if it's the optimal approach. Anyway now I
try to use TDB2 with Fuseki server.
Thanks so much

Bulkloading (TDB1) is for working from an empty dataset. The tricks it
uses do not work when there is already data in dataset. For TDB1, One
of the bulkloaders simply loads triples/qwuads, the other refuses to load.
For TDB2, which has no limits on the size of transactions, a batch size

I've about 2 triples to load each time. I load data into models with
Jena API, and write data inside a StreamWriter. When the buffer has a
certain size, I load data in the dataset with the Bulkloader. But now I'm
trying to use TDB2 with Loader.Bulkload method to see if there are
improvements,

Hi,
What is the best way to perform the bulk loading with TDB2 and Java API?
Because I used the bulkloader with TDB1, but when I store data, it's too
slow.
