Efficiently Compiling Efficient Query Plans
for Modern HardwareThomas Neumann

As main memory grows, query performance is more and more
determined by the raw CPU costs of query processing itself.
The classical iterator style query processing technique is very
simple and flexible, but shows poor performance on modern
CPUs due to lack of locality and frequent instruction mis-
predictions. Several techniques like batch oriented
