Accelerating Graph-Based RAG Retrieval via Locality-Aware Device-Cloud Collaboration

This paper proposes Lever, a locality-aware collaborative retrieval framework that exploits query locality to accelerate graph-based RAG retrieval, and identifies and empirically validate a previously underexplored property of RAG workloads: strong per-user query locality.

Accelerating Graph-Based RAG Retrieval via Locality-Aware Device-Cloud Collaboration

Retrieval-Augmented Generation (RAG) grounds large language models in external knowledge and has become a key technique for knowledge-intensive tasks. As knowledge bases continue to scale, however, the retrieval stage increasingly dominates end-to-end latency, limiting the responsiveness of RAG systems. In this paper,...
