------------------------------------

             Summary: Implementation of BufferedPlanRootSink where FlushFinal blocks until all rows are fetched
                 Key: IMPALA-8780
                 URL: https://issues.apache.org/jira/browse/IMPALA-8780
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
            Reporter: Sahil Takiar
            Assignee: Sahil Takiar


Implement {{BufferedPlanRootSink}} so that {{FlushFinal}} blocks until all rows are fetched. The implementation should use the {{RowBatchQueue}} introduced by IMPALA-8779. By blocking in {{FlushFinal}} all non-coordinator fragments will be closed if all results fit in the {{RowBatchQueue}}.
