In-memory key-value database — blazing-fast cache, session store, pub-sub, queues.
Everything in RAM = sub-millisecond latency. Persists to disk for safety. Supports data structures: strings, lists, sets, sorted sets, hashes, streams. Industry standard for the cache layer in front of Postgres/MySQL.
