Use Redis or Memcached for distributed caching.
Support TTL and size-based eviction.
Quick Answer
Advanced caching: TTL cache (cachetools.TTLCache) expires entries after N seconds. LRU cache (functools.lru_cache, cachetools.LRUCache) evicts least-recently-used. Redis for distributed caching across processes/servers. Cache-aside: check cache, miss -> load from DB -> store in cache. Stampede prevention: probabilistic early expiry or Redis locking during cache population.
