[jira] [Created] (IMPALA-9866) Query Plan Constantly Refreshes After Has Completed

Shant Hovsepian created IMPALA-9866:
---------------------------------------

             Summary: Query Plan Constantly Refreshes After Has Completed
                 Key: IMPALA-9866
                 URL: https://issues.apache.org/jira/browse/IMPALA-9866
             Project: IMPALA
          Issue Type: Bug
            Reporter: Shant Hovsepian
            Assignee: Shant Hovsepian
             Fix For: Impala 4.0


The query plan debug page fetches and re-renders the query plan graph every second event after the query has completed.

 

For large query plans this makes interacting with the graph much slower and resource intensive on the user's web browser. Also it put a strain on the coordinator node as large query plans can be several megabytes in size and is constantly re-transmitted while the user has the query plan page open.
