   Yes, since we can't change the state partitioning, state partitioning must 
be considered as the first priority for stateful operators - even we make some 
improvements here (having information of physical partitioning of state) and 
feel safer to store state as same as source's partition, the operator must 
request state's partitioning so that it doesn't break anything when source has 
changed.
