Hash Joins Meet CXL: A Fresh Look

Summary: Revisits CXL+DRAM interleaving for main-memory hash joins, presenting a phase-wise performance model that quantifies bandwidth gains versus CXL→DRAM data-movement costs. Shows selective partial movement of relations to DRAM often outperforms full relocation and offers practical guidelines for CXL-aware operator design. (summarized by gpt-5-mini on Feb 09 2026)
