[jira] [Created] (IMPALA-9888) Materialise truncations in sort

Tim Armstrong created IMPALA-9888:
-------------------------------------

             Summary: Materialise truncations in sort 
                 Key: IMPALA-9888
                 URL: https://issues.apache.org/jira/browse/IMPALA-9888
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


Related to IMPALA-7020, it would be useful to materialise truncations, e.g. if we had an "ORDER BY cast(s as varchar(4))". Currently we would include 's' in the sort tuple if it was referenced like this in the ORDER BY and the cast expr is not one of the result exprs.
