Vector Quantization in pgvector: Scaling to 50M+ Embeddings with Scalar (SQ8) & Product Quantization (PQ)
Storing uncompressed 1536-dimensional embeddings in PostgreSQL explodes RAM requirements and crashes cache hit ratios. Implement Scalar Quantization (SQ) and Product Quantization (PQ) in pgvector 0.7+.
Production RAG Chunking Strategies: Semantic, Recursive, and Parent-Document Retrieval Compared
Naive fixed-character text chunking ruins LLM retrieval precision by bisecting key sentences and isolating semantic context. Compare recursive character splitting, semantic boundary detection, and parent-document retrieval architectures for production RAG pipelines.
