turbopuffer.com 7 min read Editor score 7/10

Turbopuffer says v3 changes how documents and indexes are laid out, written, compacted, and queried, building on an object-storage source of truth with tiered NVMe and memory caches. The trade-offs offer useful context for engineers designing fast, economical search systems.

What: Turbopuffer v3 changes how documents and indexes are laid out, written, compacted, and queried to broaden search and SQL workloads.
How: It replaces the vector-primary design with a new primary index, making ANN a secondary index.
Why it matters: The redesign aims to speed text, regex, and vector search and support more SQL queries, including GROUP BY and aggregations.

The v1 vector index clusters vectors beneath a root centroid. Sketched from the article's own text.
