> We need a Scalable Cache component in Malhar. Following are some of the key features
of the cache
> 1. Cache has limited size and is backed by a persistent store.
> 2. When there is a cache miss, the data is loaded from backup store.
> 3. To minimize misses, a range of keys can be loaded.
> 4. Ability to purge key/values
> 5. Writing to the backup store should be optimized.
> 6. It should provide support for fault-tolerance.
