An Examination of CXL Memory Use Cases for In-Memory Database Management Systems using SAP HANA

Summary: First empirical study integrating commercial CXL memory into SAP HANA Cloud, evaluating dynamic capacity expansion and shared cache-coherent pools. OLTP sees negligible slowdown; OLAP impact depends on data-structure access patterns; shared CXL trims restart time ~40%–84%. (summarized by gpt-5-mini on Feb 09 2026)
