             Summary: Add concurrent unpinned reader support to BufferedTupleStream
                 Key: IMPALA-13532
                 URL: https://issues.apache.org/jira/browse/IMPALA-13532
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
            Reporter: Michael Smith


Modify BufferedTupleStream to support multiple concurrent unpinned readers. Currently it requires the buffer to be pinned to support concurrent readers.

This primarily involves additional locking around pinning/unpinning to ensure concurrent readers don't cause conflicts.
