Benchmarking Recommendations + +Before deploying to production, benchmark these scenarios: + +### Critical Benchmarks + +1. **Concurrent Write Throughput** + ```rust + // Spawn 8 threads, each writing 10K nodes + // Target: >50K writes/sec aggregate + ``` + +2. **Read Latency Under Write Load** + ```rust + // Write in background, measure read p99 latency + // Target: p99 < 5ms for get_node() + ``` + +3. **Graph Traversal Performance** + ```rust + // 2-hop traversal with 10 edges per node + // Target: <5ms per traversal + ``` + +4. **Prefix Scan Performance** + ```rust + // Iterate 100 edges via prefix_iter + // Target: <1ms per scan + ``` + +5. **Large Dataset Behavior** + ```rust + // Load 100GB dataset, measure cache hit rate + // Target: >90% cache hits after warmup + ``` + +6. **Recovery Time** + ```rust + // Crash simulation, measure restart time + // Target: <30 seconds for 100GB DB + ``` + +--- + +## Quick Start Checklist + +### Setup Steps + +- [x] **Add dependency to Cargo.toml** (already done) + ```toml + rocksdb = { version = "0.24.0", features = ["multi-threaded-cf"] } + ``` + +- [ ] **Copy configuration functions to codebase** + - `create_base_options()` + - `adjacency_list_cf_options()` + - `entity_storage_cf_options()` + - `vector_storage_cf_options()` + - `create_transaction_db()` + +- [ ] **Integrate into storage_core/mod.rs** + - Use `create_transaction_db()` to open database + - Apply appropriate CF options to each column family + +- [ ] **Run benchmarks** + ```bash + cargo bench --bench hnsw_benches + cargo test --release integration_stress_tests + ``` + +- [ ] **Monitor in production** + - Track block cache hit rate + - Watch write stall percentage + - Monitor L0 file count + +--- + +## When to Adjust Configuration + +### If writes are slower than expected: + +- Increase `max_background_jobs` to 12 +- Increase `level_zero_slowdown_writes_trigger` to 30 +- Consider switching to leveled compaction if universal is bottleneck + +### If reads are slower than LMDB: + +- Increase block cache to 60-70% of memory +- Reduce write buffer size to free up memory +- Enable more aggressive bloom filters (12-15 bits per key) + +### If storage space is too high: + +- Switch to all-Zstd compression +- Enable more aggressive compaction +- Reduce blob file threshold + +### If compaction uses too much CPU: + +- Reduce `max_background_compactions` to 2 +- Increase `level_zero_file_num_compaction_trigger` to 6 +- Consider lighter compression (Lz4 everywhere) + +--- + +## Summary + +This configuration represents a **balanced starting point** optimized for HelixDB's mixed workload: +- High write throughput via universal compaction and concurrent writes +- Fast reads via large block cache and prefix bloom filters +- Large dataset support via blob files and tiered compression + +**Expected Outcome:** +- **3-5x better write throughput** than LMDB +- **Within 2x of LMDB's read latency** (still sub-millisecond for cached reads) +- **Excellent scaling** for datasets larger than RAM + +The key advantage is that RocksDB excels at **concurrent writes** and **large datasets**, which addresses LMDB's single-writer bottleneck while maintaining competitive read performance. + +--- + +## Additional Resources + +- [RocksDB Tuning Guide](https://github.com/facebook/rocksdb/wiki/RocksDB-Tuning-Guide) +- [RocksDB
