RIP, vector database
turbopuffer is changing its storage architecture for v3, moving away from a vector-primary index to a new primary index that treats ANN as just another secondary index. This shift aims to speed up text, regex, and vector search, and lays the groundwork for faster SQL queries. The change follows customer usage from companies like Cursor, Notion, and Linear.
