Hi Nik, (I am a Data Architect by trade, fyi)
At first I saw JAVA with Blazegraph and thought, "oh dear", don't they realize what a PITA the JVM GC can be for HPC ? But then I read deeper and saw that BlazeGraph actually bypasses the GC, and they use C malloc through NIO. http://blog.blazegraph.com/?p=339 Then I thought, "Sweetness". They'll have no problems....as long as Wikidata puts an investment into arrayed system boards, like from Intel here: http://ark.intel.com/compare/61022,61021 or similar. Blazegraph should be blazing as long as you give it the necessary hardware to perform C malloc through NIO with minimal contention across DIMMS. (such as those system boards above, or something similar) Hope this helps your system designers, Thad +ThadGuidry <https://www.google.com/+ThadGuidry>
