> Partitioned states are currently stored per-key in statehandles. This is alright for
in-memory storage but is very inefficient for HDFS. 
> The logic behind the current mechanism is that this approach provides a way to repartition
a state without fetching the data from the external storage and only manipulating handles.
> We should come up with a solution that can achieve both.
