             Summary: Add client identifier to tuple cache correctness check
                 Key: IMPALA-13414
                 URL: https://issues.apache.org/jira/browse/IMPALA-13414
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Yida Wu


A follow-up task for IMPALA-12908. Currently we store the fragment id of the 
tuple cache entry as the metadata, which helps correctness checking to identify 
which fragment created the tuple cached entry. The task is to see whether we 
can also add client identifier information to enhance the tuple cache 
correctness check.
