Choosing a self-hosted vector database for your Retrieval-Augmented Generation (RAG) system involves evaluating several critical factors to ensure it aligns with your specific application's needs, performance requirements, and operational capabilities. A vector database is a specialized system designed to efficiently store and retrieve high-dimensional vectors, or embeddings, which capture the sem
