Hi Miika, a few years too late :)
We have recently published https://github.com/AtomGraph/CSV2RDF -- a streaming, transforming CSV to RDF converter based on Jena and univocity CSV parser. Not sure this is exactly what you were looking for. So far we've used it to generate up to 25 million triples, which took minutes. The Jena dependency is pretty old (3.0.1), which I can't upgrade right now because other code depends on CSV2RDF. But the codebase is really small, so it shouldn't be a problem to fork and bump it up. Hope this helps.
