SIEVE IS SIMPLER THAN LRU

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.
