Report #96400

[frontier] Re-indexing entire knowledge graphs for new documents is prohibitively expensive; how do I update RAG indices incrementally?

Use GraphRAG's incremental indexing: run the pipeline in update mode to delta-process new documents, merging new entities and relationships into the existing graph without rebuilding the community hierarchy.

Journey Context:
Naive RAG requires full reprocessing of corpora for updates, causing downtime. GraphRAG's incremental mode treats the knowledge graph as a persistent database with ACID-like updates, enabling real-time knowledge bases that ingest streams without batch reprocessing.
