Daily Term: Memcached

Memcached

Memcached is a distributed, in-memory caching system designed to speed up dynamic web applications by storing key-value pairs in memory. For example, a website might use Memcached to cache database query results, reducing load on the database. It’s simpler than Redis, focusing solely on caching with a least-recently-used (LRU) eviction policy, but it lacks advanced features like data persistence or complex data structures.
