SIEVE IS SIMPLER THAN LRU

Summary from the TLDR newsletter

Caching involves storing temporary data for quick access. Eviction algorithms determine what data to keep and what to discard. SIEVE is a simple and effective cache eviction algorithm with just one queue. It can also serve as a cache primitive for designing more advanced eviction policies. SIEVE is not scan-resistant, so it can sometimes show a higher miss ratio than other tools.
