[jira] [Created] (STORM-2740) Add caching of some blobs in nimbus to improve performance

             Summary: Add caching of some blobs in nimbus to improve performance
                 Key: STORM-2740
                 URL: https://issues.apache.org/jira/browse/STORM-2740
             Project: Apache Storm
          Issue Type: Improvement
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


In nimbus we read the topology and the topology config from the blob store all the time.  Even multiple times for a single thrift call.  It would really be great if we could cache these instead of rereading them all the time. (We have found it is a cause of the UI being slow in some cases).
