Your corpus grows by 5% daily and freshness has to land...

GraphRAG’s global modularity makes hourly updates computationally and financially prohibitive, as it requires re-running community detection and summarization across the entire graph. To meet the one-hour SLA, you should decouple the requirements: use an incremental, low-latency store for daily updates and reserve the heavy-duty GraphRAG processing for nightly batches. This hybrid architecture preserves the benefits of community summaries without violating the SLA or incurring unsustainable costs.
