Hi All:
I have been using Jena for huge biomedical application with TDB sized 3G
and around 2 billion triples and I did notice a performance issues. Thus, I
have two questions:
1- Does Jena build to handle huge app like I am developing? or do I have to
use a commercial tool ?
2 billion (2*10^9) is pushing the limits of TDB. It will only handle
very simple lookup queries at this scale.
Have you considered 4Store?
2- Does Jena a single thread or can it be ran on multi?
The query engine and TDB use one thread per request but there can be
many requests at the same time. This is what Fuseki is doing.
(Actually, there is a bit of internal multithreading for sorting)
