RIP, vector database

Turbopuffer, a serverless vector database, is undergoing a major architectural redesign called "v3" that will move away from treating the vector index as the primary index to instead making it just one of many secondary indexes. This shift allows turbopuffer to support more diverse query types and scale beyond its original specialized focus on vector search, while leveraging object storage and tiered caching for performance. The company is documenting this transition publicly, starting with explaining the evolution from its initial single-vector-ID design through subsequent versions.
