Understanding Vector Storage and Optimization in Elasticsearch 8.16.1

The article explains how Elasticsearch 8.16.1 stores dense and sparse vectors using various file extensions, compares flat and HNSW index formats, shows how disabling doc‑values removes redundant column‑store copies, and demonstrates scalar and binary quantization—including a quantization‑only mode—that can cut storage to roughly 9 percent while preserving search accuracy.
