Why the Default Vector Index Moved from HNSW to Disk — the Tradeoffs of Elasticsearch bbq_disk ♪ Listenable
As of Elasticsearch 9.4 (2026-05-05), the default index type for float vectors changed to bbqdisk — a disk-based IVF index. In under a year the default moved from int8hnsw to bbqhnsw and then, a second time, to a disk in
