CXL and the Return of Scale-Up Database Engines

Summary: Argues CXL turns a rack into a shared-memory machine, enabling scale-up DB engines via transparent pooling of memory and accelerators beyond PCIe limits. Outlines benefits for heterogeneous data systems and key research challenges (resource mgmt, coherence, performance, SW/HW co-design). (summarized by gpt-5-mini on Feb 09 2026)
