Part III — Implementation Deep-Dive

Roll up your sleeves. This section provides hands-on implementation walkthroughs of real vector database components, from a complete HNSW store in Rust to GPU-accelerated quantized search.

Chapters

#	Chapter	Key Topics
13	HNSW Store in Rust	Memory-mapped adjacency lists, unsafe optimizations
14	PQ-IVF on GPUs	CUDA kernels, fused distance computation
15	Transactional Schemes	MVCC adaptations, compaction scheduling
16	Elastic Scaling	Split/merge rebalancing, hotspot mitigation
17	Benchmark Harness	ANN-Benchmarks, synthetic data, latency suites

Prerequisites

Chapters 13–14 assume familiarity with Rust and CUDA respectively. Chapter 15 assumes database transaction fundamentals.
