Halo: A Hybrid PMem-DRAM Persistent Hash Index with Fast Recovery

Summary: Halo: a hybrid PMem-DRAM persistent hash index with log-structured storage and a volatile index enabling instant recovery. Halloc reduces write amplification; batched writes, prefetching, and reactive snapshot boost throughput and cut recovery time. (summarized by gpt-5-nano on Feb 09 2026)
