Google researchers have developed a new caching strategy called linear elastic caching, which aims to reduce cloud infrastructure costs. This method treats memory as a utility, dynamically adjusting cache size based on real-time workloads rather than fixed allocations. By framing page eviction as a ski rental problem, the system uses lightweight machine learning to decide whether to keep data in memory at a continuous cost or evict it to save space, thereby optimizing the trade-off between memory footprint and cache misses without compromising performance.
