Canonical title: KVCache Cache in the Wild: Characterizing and Optimizing KVCache Cache at a Large Cloud Provider
Question: What reuse patterns actually determine KV-cache value in production LLM traffic?
Context: KV-cache policies are often designed from synthetic multi-turn assumptions rather than cloud traces.
Method: The paper analyzes large-provider KV-cache traces and derives category-aware, workload-aware caching and eviction guidance.
Evaluation: workloads=large cloud-provider KV-cache traces; baselines=generic cache sizing and eviction assumptions; metrics=reuse incidence, predictability, and ideal capacity; results=qualitative production reuse findings; no unambiguous primary headline number recorded
Interpretation: Production cache value depends on semantic/request categories, not conversation length alone.
Reusable lesson: Measure real reuse classes before choosing cache size or eviction policy.
Applicability: Shared LLM serving clusters with cross-request prefix/KV reuse.
Limits: Trace findings may reflect one provider and period; exact intervention gains were not extracted from the primary PDF.
