Exploring query execution strategies for JIT vectorization and SIMD

This paper partially explores the design space for efficient query processors on future hardware that is rich in SIMD capabilities. It departs from two well-known approaches: (1) interpreted block-at-a-time execution (a.k.a. "vectorization") and (2) "data-centric" JIT compilation, as in the HyPer system. We argue that in between these two design points in terms of granularity of execution and uni
