Jena HDT is in-memory, right? So at first you would need enough memory to load the data. I think this would also mean that there are no indexes create, thus, the query optimizer works different.
For sure Andy S. and I guess also Rob V. (as far as I know he worked with HDT) can probably say more. I couldn't find benchmarks right now. But feel free to do some experiments and publish the results here - I'm always interested in such things. > >From rdfhdt.org: ""We provide Jena Integration to have a Jena Model on top > >of a given HDT file." > > My question is... would this model offer any advantage over TDB for larger > graphs?
