- What happened
- Turbopuffer is redesigning its storage architecture, moving from vector-indexed primary keys to a general-purpose layout where ANN becomes a secondary index.
- Why it matters
- Matters for engineers using turbopuffer for multi-vector documents, frequent updates, or non-vector query patterns like full-text search and aggregations.
- Watch out
- Version 3 currently shows significant performance regression from production. Tuning phase is underway, so stability and performance timelines remain uncertain.

The patterns behind this
- Hierarchical Index Retrieval (RAPTOR)
- Agentic Context Engineering (Evolving Playbook)
- Query Transformation Retrieval
Each one covers how the technique works, when it earns its cost, and where it breaks.
