Integrating Graph Context With OpenSearch for Enhanced RAG Application Performance
summary
Architecture that merges a graph layer with an OpenSearch vector index to ground RAG using travel-app synthetic data, either by querying a separate graph DB (Neo4j/Neptune) or by storing OpenSearch vector index as metadata triplets (from, relation, to). Claims safer, more personal results: measured recall 71%→86% (+21%), mean response time 53ms→64ms (+11%), tokens per prompt down from ~3200 to ~800 with graph-only; approach exists as a prototype (not production), warns on NER errors, caching and observability needs.
