| Feature | Implementation Detail | |---------|------------------------| | | Adaptive compaction thresholds (size‑ratio, read‑latency trigger). | | Read Amplification | Bloom filters + partitioned indexes per SSTable. | | Tuning knobs | max_background_compactions , write_buffer_size , target_file_size_base . | | Hot‑Cold Separation | Tiered compaction : recent writes stay on NVMe , older data migrates to SMR HDD . | | Snapshotting | Copy‑on‑write snapshots stored as manifest entries ; point‑in‑time reads supported via S3‑compatible version IDs . |
| Item | Value | |--------------------------|-------| | OS / Distribution | e.g., Ubuntu 22.04 LTS (kernel 6.5.0) | | FSDSS version | v3.4.2‑release | | Java / Runtime version | OpenJDK 17.0.9 | | Database (if applicable) | PostgreSQL 15.3 | | Deployment mode | Docker‑Compose / Kubernetes (v1.28) / Bare‑metal | | Network topology | Single‑region, multi‑AZ, etc. | | Other relevant services | e.g., S3 bucket, Redis cache | FSDSS-536
