ICache (apache-cassandra API)

All Superinterfaces:

CacheSize

All Known Implementing Classes:

CaffeineCache, SerializingCache
```
public interface ICache<K,V>
extends CacheSize
```
This is similar to the Map interface, but requires maintaining a given capacity and does not require put or remove to return values, which lets SerializingCache be more efficient by avoiding deserialize except on get.
