    The H‑LSM engine merges two traditional storage structures: fsdss 908

    | Component | Purpose | Data Organization | |-----------|---------|--------------------| | Mutable Log (MemLog) | Capture incoming writes at low latency | Append‑only, in‑memory segment | | B‑tree Overlay | Serve hot reads without compaction | In‑memory B‑tree indexing recent keys | | Immutable SSTables | Durable on‑disk storage | Sorted string tables generated by periodic flushes | | Background Compactor | Merge SSTables while preserving B‑tree overlay | Multi‑way merge with read‑amplification control |

    Write Path:

    Read Path:

    The hybrid design eliminates the read‑amplification penalty typical of pure LSM trees, while keeping write amplification bounded (≈ 2×) because compaction runs only on the immutable SSTables. | Component | Description | Key Specs |
