Not all applications are performance intensive. Sometimes, the worst bottlenecks are development, evolution, flexibility, and maintenance. RDBMS is a poor model for many things, with current applications force fitting models into it. In the March Berlin benchmark [1], if you look at the D2R SPARQL->RDBMS mapping, you can see one solution to having an efficient SPARQL database. It's not the model that is bad, it is the naive implementation. We are certainly going to find multiple solutions to data clustering that will provide high performance. Another thing to keep in mind is that the market moved from hierarchical databases to relational even though there was a performance loss. > Notice what project inspired those benchmarks. > Where is this plateau I am jumping beyond?
