Rethinking Execution Engines for Modern Architectures

GROUP BY aggregation with a global hash table.

The execution engine is the muscle of a database system, and most execution engines were designed for hardware architectures that are no longer dominant. As hardware platforms get more concurrency, different tiers of memory, and increasingly heterogeneous architectures, it’s time to rethink how we design and optimize execution engines. This project aims to explore new approaches to execution engine design that can take advantage of modern hardware capabilities.
