High traffic atomic push/pop between multiple clients (often used for jobs like kue.js) write coalescing - caching individual writes for later bulk inserts into a db to help insert rates. Simple counts and counters which can be incremented and then purged/reset on interval. Simple Pub/sub for medium throughout systems. Many more applications than simple key/value.
