             Summary: KeyValue State Resharding
                 Key: STORM-2962
                 URL: https://issues.apache.org/jira/browse/STORM-2962
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-client
            Reporter: Jungtaek Lim

Storm's KeyValueState leverages namespace which is typically composed to 
component name + task id, which means the key-value pair is bound to the task. 
To allow rebalancing topology with different parallelism for stateful 
component, we should support resharding of the state.

I wonder more thing about current State implementation but it should be filed 
to other issues after verification.
