DumpKV: Learning based lifetime aware garbage collection for key value separation in LSM-tree
Summary: DumpKV: learning-based lifetime-aware GC for key-value separation in LSM-trees that predicts per-key lifetime from access history to guide reclamation and reduce write amplification. Collects features during L0–L1 compaction to avoid GC throughput impact; yields 19–65% GC write reduction with low metadata overhead. (summarized by gpt-5-mini on Feb 09 2026)
