Build your own vector database
Doug Turnbull
Led Search + ML at Reddit and Shopify
Make embedding retrieval an asset, not a headache
In modern search, embeddings answer questions. They go beyond simple keyword matching to find semantically similar answers. Increasingly: RAG, recommendations, and traditional search need zero-in on what's relevant. In this class we'll live-code core data structures that live behind search systems like Pinecone, Weaviate, Turbopuffer, QDrant, Vespa, Elasticsearch etc etc etc.
By building your own vector database, you'll be better equiped to work with production vector search systems. You'll have first-hand experience with the knobs to turn to improve performance and develop a robust hybrid + vector search system
Workshop agenda
Benchmarking vector search
How we think through vector database stats: recall, latency, throughput
Building HNSW algorithm from scratch
Hands on developing the core graph-based algorithm behind search engines: HNSW
Filtering vector search
How to enhance vector algorithms to filter based on metadata
Optimizing with quantization
How to use standard quantization techniques to reduce memory, improve speed, without sacrificing recall
Layering in hybrid search
Lexical retrieval isn't obsolete - we'll talk about approaches to combining lexical and vector search into a single solution
