[frontier] How do I keep RAG knowledge graphs updated in real-time without full re-indexing?

Use streaming GraphRAG with incremental community detection, inserting new documents into the knowledge graph immediately and patching community summaries rather than rebuilding the entire graph.

Journey Context:
Naive RAG fails on complex multi-hop questions requiring synthesis across documents. Microsoft's GraphRAG \(2024\) uses community detection on entity graphs to generate global answers, but standard implementations are batch-oriented, requiring hours to rebuild indices when new documents arrive. Production systems \(2025\) are moving to incremental GraphRAG: new documents immediately insert entities and relationships into the graph \(using Neo4j or FalkorDB\), and only affected community summaries are recomputed via incremental clustering. This requires careful handling of entity disambiguation in streams. Tradeoff: eventual consistency in community summaries and higher write amplification, but enables real-time agent knowledge for fast-moving domains like financial news or threat intelligence.
