Redis as a Database

Serious question: why would you use Redis as a database instead of something persistence-focused with a lot of in-memory operations like MongoDB or something? Wouldn't one of those NoSQL stores like Mongo or Cassandra be the best of both worlds?

It depends on the shape of your data and whether or not you need extras like pub/sub. Redis (and Redis protocol compatible databases) have rich support for HashMaps, Sets etc. Previously I've used redis-persistence as the data storage for an RBAC system (Lots of sets, lists, hashmaps, mostly flat objects).

I've also heard of it as a database for online game scoring systems.

Because Redis is persistent. It's an in-memory nosql store.
