One of the findings is that compilation should always be combined with block-wise query execution. Another contribution is identifying three cases where “loop-compilation” strategies are inferior to vectorized execution. As such, a careful merging of these two strategies is proposed for optimal performance: either by incorporating vectorized execution principles into compiled query plans or using query compilation to create building blocks for vectorized processing.
