[jira] [Created] (ZEPPELIN-4985) Instant visual feedback on high latency network environment

Lee Moon Soo created ZEPPELIN-4985:
--------------------------------------

             Summary: Instant visual feedback on high latency network environment
                 Key: ZEPPELIN-4985
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4985
             Project: Zeppelin
          Issue Type: Improvement
    Affects Versions: 0.8.2
            Reporter: Lee Moon Soo


In high latency network environment (between web browser and zeppelin-server), some user actions on the browser (mouse click, keyboard input) such as 'run paragraph' and 'switch visualization', first send message to zeppelin server and wait for response message before making any update in the ui.

This make user feel ui 'freeze' for a while. Especially on frequent actions, like 
 * run paragraph
 * switch visualization

can make instant visual feedback without waiting for server response, like
 * run paragraph -> change paragraph status to PENDING
 * switch visualization -> switch visualization immediately, without waiting for server response.
