This paper synthesizes recent literature on RAG system design, specifically focusing on mechanisms for continuous learning. Building on frameworks by Zheng et al. and Zhang et al., we analyze architectures that support continuous memory addition, deletion, consolidation, and re-weighting. These mechanisms transition RAG from static retrieval to incremental learning, mirroring biological memory processes. Our analysis demonstrates that dynamic memory architectures outperform static systems in adaptability, robustness to distribution shifts, and long-term retention.
