Amazon Proposes Per-Request Validated Evidence Caching for Production RAG
_reachsumit · x · 2026-10-16
- An Amazon Science paper proposes Safe and Sufficient Caching: caching evidence chunks in production RAG systems while validating access permissions and source freshness before each reuse.
- The approach cuts latency and retrieval cost with zero invalid reuse, targeting production settings where evidence timeliness and access control matter.
