> There are cases when the user code needs access to a 'cache' which can be used to store custom data. This cache is different from the KeyValue store in the following ways:
> * At the very least Needs to support LRU (Least Recently Used) and TTL (Time To Live) eviction strategies
> * May not support all() and range() operations (since this wreaks havoc with the eviction operation)
> * Needs to exist at a per task or a per container level.
