Configuration Driven Rag Customization Via Yaml Workflows

via “configuration-driven component factory instantiation”

⚡FlashRAG: A Python Toolkit for Efficient RAG Research (WWW2025 Resource)

Unique: Implements a unified factory system across 6 component types (retrievers, generators, refiners, rerankers, judgers, datasets) with YAML-based configuration merging and runtime override support, enabling zero-code component swapping — most RAG frameworks require code changes or separate instantiation logic per component type

vs others: Faster to iterate on RAG experiments than LangChain (which requires Python code for component selection) or manual instantiation, while maintaining type safety through base class inheritance
