- 7Hacker News·10/1/2026product_launchTurbopuffer shifts from vector-first storage to a new primary index
Turbopuffer says it is redesigning its storage architecture in v3, moving away from a vector-primary design and making ANN a secondary index. The company says the change will improve text, regex, vector, and broader SQL query performance, while removing constraints on operations like GROUP BY and aggregations.

Amazon DynamoDB now supports native vector search, letting developers store embeddings with application data and run approximate nearest-neighbor queries directly in the database. The feature also includes filtered similarity search and configurable vector indexes for semantic search workloads without requiring a separate vector database.
