SepHash: A Write-Optimized Hash Index On Disaggregated Memory via Separate Segment Structure
Summary: SepHash: a write-optimized hash index for RDMA-based disaggregated memory that uses a two-level separate-segment structure to slash resize bandwidth and a low-latency concurrency-control to avoid unnecessary mutual exclusion on inserts. With an efficient cache and filter for reads, SepHash achieves ~3.3x higher write throughput than state-of-the-art distributed hash indexes while preserving comparable read performance.
