IcebergHT: High Performance Hash Tables Through Stability and Low Associativity
Summary: IcebergHT uses stability (no item movement) and low associativity (few candidate slots) to minimize cache-line traffic and enable crash-safe updates. Iceberg hashing with in-memory metadata is space-efficient and fast, delivering PMEM inserts 50%–3× faster and queries 20%–2× faster, with ~17% space overhead.
