Nephele: Bridging DDR–CXL Latency Gaps with Benefit-Aware Caching for In-Memory Databases on Hybrid Memory

In-memory databases rely on DDR memory for performance, yet capacity scaling is impeded by physical constraints and the high cost of high-density DIMMs. Compute Express Link (CXL) provides a practical path for memory expansion through a DDR-compatible interface. However, CXL memory exhibits inferior latency and bandwid...
