Optimizing performance by reducing the amount of CPUs cycles wasted in these useless work have been a long time focus of MoD Ern compilers.
Spark 2.0 ships with the second generation tungsten engine.This engine builds upon ideas from modern compilers and MPP databases and applies them to data processing. The main
