RAG Architecture: Vector Store Choice Hinges on Retrieval Problem, Not Just Benchmarks

Choosing a vector store for retrieval-augmented generation (RAG) projects requires a deeper understanding of the specific retrieval problem rather than just comparing vendor features or benchmarks. The decision should be guided by factors such as the scale of data, the nature of user queries, and the necessity of metadata filtering for security and relevance. Production RAG often benefits from hybrid retrieval methods combining vector search with keyword matching and robust filtering, while also considering operational aspects like reindexing, monitoring, and cost.
