S !"#$ : A Scalable and Resize-optimized Hash Index on Disaggregated Memory

A novel architecture called S !"#$, designed to enhance the performance of hash indexes in disaggregated memory, is introduced and the results show that S !"#$ outperforms state-of-the-art DM-optimized hash indexes by at most 6.7 → (RACE), 3.6 → (SepHash), and 1.8 → (Outback) in YCSB workloads, respectively.
