[jira] [Created] (IMPALA-9210) Query timeline should include entry when all query results are spooled

Sahil Takiar created IMPALA-9210:
------------------------------------

             Summary: Query timeline should include entry when all query results are spooled
                 Key: IMPALA-9210
                 URL: https://issues.apache.org/jira/browse/IMPALA-9210
             Project: IMPALA
          Issue Type: Bug
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


Adding this to the query profile would help debug slow clients. If there is a large difference between when all results are spooled vs. the client has fetched all results, it is likely that there is something causing the client to fetch rows slowly (or perhaps row materialization is slow).
