I'm under the belief that Redis is much faster than Cassandra, am I crazy to think that Apple or any company really should have a transition plan? Why isn't redis used more?


Cassandra solves different problems than Redis is typically used for.


Redis is for when your data fits in memory.


By default redis will drop your data when under memory pressure. It’s a different thing.


Redis is a cache


Redis is not simply a cache. It can be used as one but it supports many other data structures and use cases beyond that.


Redis is not a cache. It has all kinds of data structures.
