LightRAG hits 30k stars, adds unified storage backends

LightRAG is rapidly becoming the pragmatic alternative to Microsoft's GraphRAG for developers who need graph-based context without the prohibitive indexing costs.

• –Dual-level retrieval (local/global/hybrid) effectively bridges the gap between precise fact-finding and broad thematic synthesis.
• –Native support for incremental updates solves the primary pain point of traditional graph-based systems that require full re-indexing.
• –Recent integration of OpenSearch and PostgreSQL as unified backends significantly simplifies the "RAG stack" from four databases down to one.
• –Built-in citation support and WebUI for graph visualization make it a complete, developer-friendly package for production-ready agentic RAG.
• –Performance benchmarks suggest a 2x-5x reduction in API token usage compared to global-only graph retrieval methods.
