PartitionKV: Redesigning LSM-tree KV Stores on NVMs with Adaptive Partitioning for Reducing Write Stalls and Amplification
Summary: PartitionKV rethinks LSM KV stores on DRAM-NVM-SSD by replacing unordered MemTable/L0 with ordered NVM partitions that act as both write buffer and WAL. Adaptive split/merge partitioning plus multi-threaded compaction cut L0-L1 rewrite, reducing write stalls/amplification and boosting random writes. (summarized by gpt-5-mini on Apr 11 2026)
