--------------------------------------
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.
