Hello Kingsley, I have to add that the potential complexity of SPARQL queries is not really an argument against SPARQL. There are problems that cannot be effectively parallelized in any way and there are problems that cannot be effectively parallelized within a triple store but with other specialized means. But IMO there is no general purpose technology that realizes all those other specialized means. Things like MapReduce are programming models - not something I can throw data into and query :-) Regards, Michael Brunnbauer On Wed, Apr 17, 2013 at 09:35:16PM +0200, Michael Brunnbauer wrote: > > Hello Kingsley, > > On Wed, Apr 17, 2013 at 02:58:18PM -0400, Kingsley Idehen wrote: > > This is all about scalability ultimately being out of the hands of > > SPARQL and placed back into the hands of computing resources (which > > includes: the SPARQL processor, host operating system memory, and > > hardware components such as CPU, disk, interconnects etc..). > > But those resources only scale by adding more computers.
