[jira] [Created] (STORM-2438) on-demand resource requirement scaling

Robert Joseph Evans created STORM-2438:
------------------------------------------

             Summary: on-demand resource requirement scaling
                 Key: STORM-2438
                 URL: https://issues.apache.org/jira/browse/STORM-2438
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
    Affects Versions: 2.0.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


As a first step towards true elasticity in a storm topology we propose allowing rebalance to also modify the resource requirements for each bolt/spout in the topology.  It will not be automatic, but it will let users scale up and down the CPU/memory needed for a component.
