[jira] [Created] (STORM-3003) Nimbus should cache assignments to avoid excess state polling

             Summary: Nimbus should cache assignments to avoid excess state polling
                 Key: STORM-3003
                 URL: https://issues.apache.org/jira/browse/STORM-3003
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-server
            Reporter: Kishor Patil
            Assignee: Kishor Patil


Since nimbus ( scheduler generates assignments) it can cache it instead of polling for it from ZK or other state manager.

This would improve scheduling iteration time, as well as all UI pages that require assignment information.
