This survey paper introduces a novel, system-behavior-oriented taxonomy for categorizing techniques that optimize Key-Value (KV) cache infrastructure during large language model (LLM) serving. It analyzes existing methods based on their temporal, spatial, and structural behaviors, identifying patterns of co-design and pinpointing six critical open challenges for efficient, reliable, and trustworthy LLM deployment.
Key insights
- Structural optimization methods (compression, retention management) are the most prevalent and directly contribute to memory savings in KV caches.
- Temporal behaviors (execution, scheduling, pipelining, hardware-aware execution) are crucial for directly reducing latency and improving throughput by addressing computation stalls and under-utilization.
- There are significant opportunities for co-optimization across different behavioral dimensions, particularly co-design between hardware-aware execution and compute device orchestration, while KV cache compression remains largely isolated.
