> Currently each streaming task initializes the entire topology regardless of 
> the assigned topic-partitions. This is wasteful especially when the topology 
> has local state stores. All local state stores are restored from their change 
> log topics even when are not actually used in the task execution. To fix 
> this, the task initialization should be aware of the relevant subgraph of the 
> topology and initializes only processors and state stores in the subgraph.
