SHARD: A Scalable and Resize-optimized Hash Index on Disaggregated Memory
Summary: SHARD is a DM-aware hash index that leverages Iceberg Hashing to map keys to fewer buckets and an Ordered-CAS protocol to minimize RDMA reads/writes while ensuring correctness with duplicates. Lazy resizing plus RDMA-combining and adaptive synchronization avoids costly coordination, yielding up to 6.7×/3.6×/1.8× speedups vs RACE/SepHash/Outback on YCSB.
