[jira] [Created] (IMPALA-11123) Optimize count(*) for ORC scans

Quanlong Huang created IMPALA-11123:
---------------------------------------

             Summary: Optimize count(*) for ORC scans
                 Key: IMPALA-11123
                 URL: https://issues.apache.org/jira/browse/IMPALA-11123
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Quanlong Huang
            Assignee: Pranav Yogi Lodha


IMPALA-5036 and IMPALA-6501 added an optimisation for count(*) in Parquet and Kudu scans that avoids materialising dummy rows. We should do something similar for ORC.

Refer IMPALA-5036 for more details.
